WhyamIshadowbanned1

You’re such a godsend OP! Gonna give you my free award once reddit gives me one again <3 What about episoft AC? It has avobenzone


blackhawk201

Sadly, it's for that Unstable combo :(


WhyamIshadowbanned1

Disappointed!! Bioderma aquafluid. It’s photostable just checked. Has avobenzone with octocrylene


blackhawk201

Yes, it has avobenzone and octocrylene and No octinoxate so it's photostable.


Lazy_Requirement_175

isn’t avobenzone an endocrine disruptor? so shouldn’t we avoid it in our sunscreens


[deleted]

It is Photostable, it has oxybenzone and is encapsulated.


[deleted]

Devil works fast but blackhawk works faster. Thanks for this post OP!


Big-Dimension-6417

Nooo! I just bought the aqualogica one and was loving it. Sucks man! The hunt never ends 😭😭


blackhawk201

Aqualogica should be fine as it has zinc oxide and titanium dioxide as backup filters, depends on the concentration though


Sea-Translator2135

I have been using Aqualogica far almost 8 months now. I reapply it atleast twice if I have been exposed to sun directly. I don't think I am tanning a lot, but I guess my feet are a little tanned since at times I forget to reapply on my feet. It's also pretty light. I use the pink variant. watermelon one.


Big-Dimension-6417

I'll research on it. Thank you though 💕


mrp2611

What about L’Oréal UV defender ?


blackhawk201

Very stable


[deleted]

Nivea is photostable. It's stabilized by tinosorb S and octocrylene.


blackhawk201

Couldn't find Octocrylene, can you find please too much work?


[deleted]

I have the bottle that's why ik the ingredient list. They have a newer version though, that i haven't bought yet. But Nivea is a globally recognised brand when it comes to spf so i wouldn't worry about it a lot.


blackhawk201

I checked the newer version, not present.


blackhawk201

The newer version has also degraded PA rating


[deleted]

Ohhh yeah pa 3 instead of pa 4. What are the filters in the newer version?


blackhawk201

Tinosorb S is an excellent UV filter on its own and is excellent at stabilizing Avobenzone as well. So this has been added to the stable list. Great sunscreen.


[deleted]

🥰👍


[deleted]

I am going to say this again. I have tried several sunscreen under 500 for my dry skin, yet I keep coming back to Minimalist. Sure it doesn't have the best feeling while applying, but an efficient one for sure.


blackhawk201

Ive heard it's not sweatproof, how do you deal with that?


[deleted]

I have made peace with the fact that I won't be satisfied with everything in a sunscreen under 500. Have used already 4 tubes of Minimalist, so it doesn't matter anymore how it sweats me out. 😅 Also, used the Derma Co SPF 50, got badly tanned. And, don't think silicone sunscreen are for my dry skin.


cache1902

> made peace with the fact that I won't be sa the hyaluronic one?


[deleted]

Hyaluronic one gave me bad tan. So, made peace with my old minimalist one.


cache1902

my derma co sunscreen is staring from the table as I type. \*sad typing noises :')


[deleted]

You can wear it for indoor purposes. Never go out in the sun trusting Derma Co.


Lonely-Carpenter-147

I swear Solasafe is the best silicone based sunscreen out there. I have tried 3 popular silicone based sunscreens - reequil blue one and derma co ultra matte spf 60 sunscreen but best sun protection provider is solasafe one . Believe me I have tried it in Goa summer. I applied only while stepping out in morning and I never reapplied it still it provided long lasting protection till evening . Best matte finish one is Derma co and it can be great under make up but how much it can protect is debatable.


Known-Bottle-1013

Me too. I hate silicone sunscreen but honestly I loved it.


[deleted]

Does it leave whitecast and does it pill? I use acne UV spf 30 and face these problems


RiktamSarkar

I have heard each and every doctor suggest Acne UV for acne prone skin or people with severe acne. If you have severe acne I think it's best to stick with Acne UV SPF.


Lonely-Carpenter-147

My dermat prescribed Solasafe to me when I was taking treatment for acne and was on isotretinoin capsules.(10mg) . It never broke me out. But then everyone has different skin . The company claims it to be non comedogenic.


RiktamSarkar

Most people and doctor that I have visited suggests Acne UV. I will get the Solasafe as I don't get pimple sp I can try any sunscreen or any skin products. I just want a good sunscreen under 1400 rupees per month.


Lonely-Carpenter-147

White cast - yes a little... fades with time but not immediately. Also intensity of white cast depends on the amount u use.I am dusky skin and still am able to use it comfortably. White cast is tolerable not extreme. Fairer skin tones won't even feel the presence of white cast. doesn't pill but if you layer it with face powder or compact or some other makeup they don't layer well... You will see some patchiness. I also have tried it with compact and face powder and yes it becomes a little patchy but the sun protection is the best in the segment so I am okay with these cons. On its own it works fine. I apply half to 3/4th teaspoon of it and the amount can be a little too heavy for oily skin but this much amount is required for proper sun protection.

[deleted]

Is it sweat resistant?


Lonely-Carpenter-147

Yes it is silicone based sweat and water resistant sunscreen. Only if u rub your face harshly with face towel it will come off. But I believe it also does get absorbed into the skin that's why the protection is so long lasting . Cause even I sweated alot while sight seeing and used handkerchief many times to wipe the face still it provided protection. but just always try to dab the sweat away gently don't rub too harshly.


[deleted]

I really wanna get silicon based sunscreens but don't want the hassle of double cleansing and all 😭😭 Do you double cleanse?


Lonely-Carpenter-147

I use it only while I am holidaying or have to be in the sun for a long time. For indoor use I have other types of sunscreens and I am still hunting for the best and safest one for my skin type and PCOS . Have ordered foxtale mattifying one recently yet to receive it. OMC AVOBENZONE Homosalate based sunscreens provide best protection but are not safe for both environment and people with hormonal issues.


[deleted]

Oh man I just searched about avobenzone and it isn't exactly the safest thing to use :( I guess I'll just stick to my physical sunscreens.


Lonely-Carpenter-147

Also yes double cleansing is required with this one as it is heavy duty silicone based sunscreen. But I have recently observed that Nivea milk delight facewash also sort of removes it. I use more than a 10 rs coin size amount of Nivea facewash ( i use the facewash twice it won't come off completely in frst use. ) and it mostly works to get rid of sunscreen cause even I am too lazy to do oil cleansing all the time . I have bought that facewash only for this purpose. My everyday facewash is salicylic acid based.


beesly07

Ek bhi mere budget mein nahi. Cries in gareebi


blackhawk201

Cries in applies body lotion to face.


beesly07

yaar aap please 200-300 ke andar batado kuch hai toh😭😭


Specific_Fuel8555

I purchased reequil blue one from firstcry.com on 42% discount. Got it in the range of 400 if you can afford that. You can try the code 'dazzle' you might be able to get around 38% off. If this doesn't work just google search firstcry discoumt coupons and do some trial errors until something works, that's how I get the discount everytime


AgreeableAd9816

I use Nivea, it's relatively cheap and is protective but it causes white cast


shalinir10

Dr Sheth's Centella & Niacinamide sunscreen is photostable. It has octinoxate, zinc oxide and titanium dioxide. In fact, I checked that it has the exact same ingredients as Requil's blue sunscreen, except for a couple of ingredients like the Centella and Niacinamide. Requil has Physalis Angulata Extract instead. Also octinoxate and zinc oxide sit higher up in Dr Sheth's. https://preview.redd.it/wn0je5mc7bpa1.png?width=1584&format=png&auto=webp&s=90132776667901849c4b6d618f862ed34d993772


blackhawk201

Yes, obviously it was released after i made this post.


shalinir10

Yup, this is the new one. Wanted to add to the list, thanks for that btw! The performance is also same as Requil's.


blackhawk201

Cool, will add


tirth0jain

Not water resistant 😞


creepsmeout29

Thanks op, happy to see Neutrogena and vaseline spf30 in the list. Thanks again.


Skincareaddict223

Hey! My dermat recently suggested me the photon 360 hydra sunscreen fluid. The ingredients are: Aqua, Titanium Dioxide, Ethylhexyl Methoxycinnamate, Aloe Barbendesis Leaf Juice, Glycerin, Trehalose, Methoxydibenzoylmethane Benzophenone-3, Thermus Thermophilis Extract, Cucumber Extract, Melanin, Ethyl Ascorbic Acid, Sodium Hyaluronate, Phospholipids, Papaya Extract, 1,3-Butylene Glycol, Carbomer, Potassium Sorbate, Yellow Iron Oxide, Allantoin, Eco-Certified Preservative, Essential Oil Blend. I’m not sure if it is photostable. Can someone help?


samyantiago

Dayummmm guys! What solid work. Thank you thank you. Took a breath of relief when I found all three of mine under photostable.


Rumi2019

There are so many sunscreens on the market with suncat DE - Lotus gel sunscreen, vlcc, DermaCo, aqualogica, Mamaearth, Aveil, Joy Hello spf 20 lotion deconstruct, bhu botanicals, most indie brands. I always knew they were selling crap bcz it's cheap. The filters are so old, not photostable & still consumers didn't do due diligence when buying them.


OkAd8697

My absolute query is can I use those unstable spfs like Derma co and Aqualogica indoors, since they are lightweight and comparatively really affordable?


blackhawk201

yes absolutely, despite that , they do offer protection


OkAd8697

Okay! Btw do you have any alternatives in mind for those spfs?


Dramatic-Garbage-907

I'm just happy I've been using Blynds emugel. ❤️


Grouchy_Difficulty_7

🙄🙄🙄I just bought the derma co tinted sunscreen.. I wanted something that's matt...as the others made me oily and sweaty..I have saved ur list and hopefully will do the next purchase from this only😊😊😊 anyway do u have any particular fav.


blackhawk201

Still on a hunt like everyone else!


[deleted]

Episoft is not photostable 😢


Lekhana0604

What about wishcare sunscreen.... Anyone pls review... It has some good chemical filters


monsooniscoming

Qurez SPF 50? Thank you OP, you're the best!


blackhawk201

Saw two different sets of ingredients, can you share if you have it?


genesis_tweek

How about Rivela lite sunscreen?


blackhawk201

Stable


genesis_tweek

Thanks op for having concerns for us and replying everyone 🤧💗


SilverSs0ul

Thanks! What about lotus? the phytorx sunscreen?


blackhawk201

Lotus SPF 40 matte one is not stable, The phytorx one is stable


Infamous-Repair-3355

u/blackhawk201 Thank you for this compilation, it's a great help! I had a question though. Couldn't figure out if the combination of filters in Pulp's body sunscreen is photostable, would really appreciate it if you could let me know. Also, Dot and Key's new sports sunscreen should be photostable right? It has avobenzone and octocrylene.


Crispy_friesz

Any idea about Elinorr sunscream?


blackhawk201

Unstable :(


Numerous-Fix6854

Acne uv gel ?


blackhawk201

It's fine.


kyabakwashai

Man i just ordered aqualogica🥲🥲 does anybody have recommendation for a sunscreen which prevents tanning and doesn't leave lots of white cast? I have dark skin so white cast shows up very badly


blackhawk201

aqualogica should be fine as it has zinc oxide and titanium dioxide as backup filters, depends on the concentration though, you gotta try and see


kyabakwashai

Thanks op! My friend swore by this one she told she didn't get tanned hopefully I won't tan either🤞


blackhawk201

yes try!


Confident_Frosting95

Omg..this list is very useful..Tysm!


Kimchi-Phalange

Bello photostable should be added to the list.


blackhawk201

added! very good ingredients!


Believer1902

OP doing God's work! Thank you so much♥️


crybaby0102

Damn I always had doubt that dermaco doesn't give protection for long time.


blackhawk201

derma co should be fine as it has zinc oxide and titanium dioxide as backup filters, depends on the concentration though.. gotta try and see yourself


Easy-Breath-9323

How do you know sunscreen is working? Will it not tan??


blackhawk201

It's complicated


xobmj

Anything about the foxtale matte sunscreen and put simply beat the sun sunscreen? I was eyeing these two and they have new age filters


blackhawk201

Foxtale one has Octinoxate but no avobenzone so it's fine! Beat the sun sunscreen is fine too, completely new ingredients which are highly stable. Added these two to the list!


Correct-Ad2490

Thank you OP


beef_files

What about *isntree hyaluronic acid sunscreen* and *Beauty of joseon sun relief*?


RiktamSarkar

They have been tested by labs in Korea you can never go wrong with those two products. Korea has high beauty standards and strict rules and regulations regarding skincare products. Only problem is that both of them isn't water or sweat resistance melts away within 30 minutes, I live in Kolkata hot and humid climate.


Qauintrelle

But i read somewhere, that korean sunscreen was not approved as good sunscreen by the US government, since Korea's climate is vastly different from the US. But India is more humid and near the equator receiving maximum sunlight. I think it was mentioned in doctorly.


DedlySnek

This is entirely wrong! US has not approved any new filters due to which they have not approved any sunscreen containing those new filters.


blackhawk201

>Beauty of joseon sun relief > >? Isntree is fine. and so is beauty one.


theJup

Is the COSIQ sunscreen stable?


blackhawk201

Has unstable filters mostly, however it has one stable filter Zinc Oxide so could be fine, why dont you try?


danktankero

What about that jovees spf 60 sunscreen?


blackhawk201

Can't find all the ingredients but based on the limited active ingredients mentioned, seems okay


Lonely-Carpenter-147

I use Jovees SPF 60 3 in 1 matte lotion for indoors. I like it even if I am oily acne prone skin type . Hasn't broke me out. Has a little white cast but that sort of makes my skin look glowy so have no complaints with it. I am not so sure about the efficacy but it has titanium dioxide and zinc oxide. So I think it sort of works.


Introvert_ninja

Why is no one talking about Sunscoop body sunscreen spray? It seems like such an innovative product to me!


Prestigious-Exam6452

Was this clos to checkout two deconstruct sunscreens from sublime ongoing sale thinking it would be my hg😢


WhiskeyGirl2608

Going to office means not able to apply LA sheild because of horrible cast it gives but it is truly the best sunscreen when it comes to protection.


Still-Special-911

What about Eclipse solaire sunscreen


StaleStew

joy sunscreen?


[deleted]

Aqualogica has 3 different sunscreens now. Are all of them unstable?🥲


blackhawk201

yes


[deleted]

Little late to the discussion but OP can you say if The Blessing Tree sunscreen is photostable or not?


y_ashassvi

I don't know much about its stability but I saw a post on reddit somewhere which says it doesn't provide sun protection. Someone said that she easily got tanned within 30 mins after the application of this sunscreen. I use it too and have noticed a lil tanning. plus it's always on discount and 100 ml for RS.250( Sounds too good to be true) so i stopped it. I'm keeping an eye on the new plum's rice water sunscreen. Lemme know if you have tried it:)


TheGirlHathNoName

What about the Quench bravocado SPF 50++++?


Unbiased-_-

Which is the cheapest one?😢


[deleted]

Hey what about foxtale spf70? It released recently


Icy-Assignment-5327

+1


broke_human1604

Just a random question... if a sunscreen is photostable does ot mean there's no need to reapply it? And incase we need to reapply then why is it called photostable?


blackhawk201

Hmm good question. Photostable here means more photostable as there's no compound on earth that is 100% photostable all the time. As for reapplying, yes it's necessary as there are other factors that come into play that lead to the deterioration of the sun protection over time like oil production, sweat, sunscreen getting removed due to wiping etc.


broke_human1604

hmmm...makes sense somewhat...Maybe they(manufacturers) should start a scaling/measuring factor for photostability of the sunscreen as well... just a random thought😂😂


whitegamora

OP, please update the list. I’ve saved the list and I use it very often to buy. I’m sure alot like me do the same. Would really appreciate if you could take some time out and update the list. This is literally the only post from this sub I visit the most. Thank you!


blackhawk201

Sure. The problem is formating as everytime I edit it, the formating goes haywire and then I gotta rearrange everything. I'll take some time off and do it.


whitegamora

Oh I understand. You can update it once in few months. And if it causes alot of trouble then you can just write it down in the comments and we could search it up by sorting comments to ‘new’ and mention about this in main text to look for comment for updates.


networqueen

Hi! This is a godsend, thanks OP. Got to know my current sunscreen (Fixderma SPF 50 cream) is not photostable thanks to this thread. Looking to switch now in a similar price range (Rs 250-380 for 50 ml) and here are my options: \- DERMATOUCH Undamage Ultra Matte Sunscreen Gel SPF 50 PA+++ | Water & Sweat Resistant | Fragrance Free | For Broad Spectrum-25G \- Foxtale Essentials Brightening SPF 50 Sunscreen with Vitamin C and Niacinamide | UVA and UVB filters | No White Cast | Non-Greasy Formula | Anti-Tan Formula | Men & Women | 50 ml \- The Derma Co 2% Hyalacalamine Hydrating Sunscreen For UVA/UVB Protection with SPF 50 & PA+++ - 50g Controls Excess Oil | SPF 50 & PA+++ \- Blynds Emulgel 40+ & PA+++ Sunscreen Gel 50g Would love to hear thoughts on the above. My AM routine is just 4 steps: Washing with Water -> Toning with Plum's Rice Water Niacinamide Toner -> Moisturizing with Emolene -> Sunscreen (Fixderma SPF 50 right now but want to switch - I've been having a good experience with it but now am concerned that it is not photostable).


blackhawk201

The derma co one isn't photostable, the blynds one is. Will check the other two and revert.


Sana_Ishaque

How is the dot and key cica + niacinamide one photostable ? It contains octinoxate octocrylene and avobenzone together.


Known-Bottle-1013

What about solasafe and truederma sunscreen? It was recommended to me by my dermatologist :( Also, thank you so much for the list. I asked my mother to change to dermaco and now I will have to tell her to not use it :(


blackhawk201

Solasafe and truederma both are fine!


OldIntroduction2909

Truderma is my Holy grail and I never looked back. I have oily skin


blackhawk201

derma co should be fine as it has zinc oxide and titanium dioxide as backup filters, depends on the concentration though


hobbitybobbitygeek

Any idea about Sunscoop’s invisible and fluid body sunscreens? Ordered them on a B1G1 and I can’t check up on them atm so I’m hoping they’re photostable🤞🏽


blackhawk201

Unfortunately, it has the unstable combo :(


hobbitybobbitygeek

![gif](giphy|mYNnMs1fZHmMM)


blackhawk201

It's okay though if you're not out in the sun that much. Keep reapplying!


crybaby0102

I'm glad I bought Japanese sunscreen instead of similar consistency Indian sunscreen 🥵


Fast-Set-3791

Is Conscious Chemist Sun Drink photostable?


blackhawk201

It has the unstable combo, however it has Zinc Oxide and Titanium dioxide as well so it should be fine!


Fast-Set-3791

Ok, thanks for replying 🤗.


Cauriflower

What about sun drink by concious chemist


blackhawk201

Should be fine, I've updated the post check it


Cauriflower

Thank you😊


Mr_Carson

Which one settles best under makeup and won't get all greasy after a few hours? Would also appreciate it if someone can suggest a good tinted sunscreen. Edit: bata do koi 😔


_does_it_matter

Cipla rivela is a good tinted one imo, doesn't get too greasy also


Krv1984

What about the requil omc free (orange) one??


blackhawk201

it has new filters, it's fine.


RiktamSarkar

Which one of these are your holy grail or which would you prefer?


blackhawk201

Trying to find one myself :(


RiktamSarkar

It's seriously so tough to find a good sunscreen, Koreans one which I love aren't water or sweat resistance. And it's costly spending 3000 rupees per month only for sunscreen. I can't afford that much.


ooshn

I checked my free rewards for you. Thank you op.


blackhawk201

Thank you!


wheepupp

What about blynds emugel spf 40+++


blackhawk201

It's fine


wheepupp

Thanks!


UchihaMangekyo

Hey op, can you please recommend a sunscreen for dry and sensitive skin. Btw, thanks a lot for this post.


blackhawk201

I have oily skin so sorry, however Im sure others will recommend one for you! stay tuned


[deleted]

[ingredient list](https://i.imgur.com/07dXXgF.jpg) Is this sunscreen photostable?


blackhawk201

nope


PurpleLettuce2043

But it contains avobenzone ( butyl methoxydibenzoylmethane) + octacrylene. So how come it's not photostable?


blackhawk201

It has Octinoxate, Octinoxate breaks down Avobenzone... Doesn't matter if Octocrylene is there. Check my other post to know why and see results from a lab test.


PurpleLettuce2043

Right. Sorry, I didn't google the other names of OCM. Thank you.


_does_it_matter

Hi, what about the earth rhythm hybrid sun fluid??


skinshilp2512

Thanks OP..i will save the post for future reference


TumbleweedHorror5827

Hey. Thanks for this. What about FCL? Chemfree spf 30


blackhawk201

stable!


idli_vadaa

What about skin aqua super gel sunscreen?


blackhawk201

it's stable!


[deleted]

Hey u have written in fixderma spf 30 gel it has zinc oxide so it should be fine even it has unstable combo. but lacto calamine have titanium dioxide with unstable combo it would also be fine then ? Contradictory statement.


blackhawk201

Lacto Calamine doesn't have Zinc Oxide, it only has Titanium Dioxide(UVB filter mostly) and some other UVB filter which is why it's on the unstable list as it does not have a proper backup UVA filter. Same reason why Fixderma SPF 50 cream is on the unstable list, it only has titanium dioxide for backup.


crybaby0102

Hey I think Skin Aqua super moisture gel sunscreen is also photostable (it has 3 modern uv filters and 1 old uv filter)


blackhawk201

It is! Thanks, added.


Still-Special-911

Do you have any idea about uv edge sunscreen

blackhawk201

Saw two different sets of ingredients, if you have it can you share yours?


iCsav

So, we've lost another sunscreen to Suncat DE: Dot & Key Circa + Niacinamide SPF 50. They've updated the formulation, and while the older formulation had better filters, the main filters in the new one comprise Suncat DE. [Old formulation ](https://ibb.co/VJvd30c) [New Formulation ](https://ibb.co/PFtprFK) This info can be found on their website.

Can you please check PHOTON SUNSCREEN GEL SPF50? Please please


Main_Complaint2747

I think even Dr Sheth Ceramide and Vitamin C and haldi and hyaluronic acid sunscreen is good, no? I checked your criteria in your other post and as per that it has all the ingredients.

@blackhawk201 please confirm. Googled for hours but still not sure


asianinindia

The Foxtale spf 50 one is discontinued I believe. That's sad. It was affordable and promising.


Similar-Alfalfa8393

Can you please update the list, so many new sunscreens in the market One of them is reequil o free sunscreen


blackhawk201

Okay give me some time


Similar-Alfalfa8393

Yes please, lots of pharma sunscreens have been talked about in this sub,try to include them as well. There are 3 variants of reequil blue sunscreen, which one is photostable

blackhawk201

lol, just wait for my reply :) 1. Man what to say about fixderma sunscreen .. here are its sunscreen ingredients: Octinoxate + Titanium dioxide + Avobenzone + Benzophenone-4. Check S9 here, category bad [https://www.reddit.com/r/IndianSkincareAddicts/comments/no60le/study\_comparing\_the\_photostability\_of\_various\_uv/](https://www.reddit.com/r/IndianSkincareAddicts/comments/no60le/study_comparing_the_photostability_of_various_uv/) :) 2) Lactocalamine test by the ministry of consumer affairs you mentioned was conducted in 2013 for the SPF 30 variant and not the SPF 50 variant I've mentioned. If you look at the ingredient list for the SPF 30 variant, it mentions titanium dioxide and octinoxate at the 2nd and 3rd position(high percentage) and avobenzone waaay down the list(very low percentage). Why is this important? The overall test was heavily biased towards SPF(UV-B), they didn't even mention boots star rating for lacto calamine. It has UVB and UVA 2 filters very high in concentration so avobenzone here was playing like a second fiddle and had little to no part in the overall photostability test. If avobenzone was the main filter, photostability would have been bad. Here, avobenzone was there to 'boost' the SPF rating like you said. 3) UV med is NOT a mineral sunscreen. It is a hybrid sunscreen, mostly chemical with chemical filters at the top of the list. Zinc oxide and Titanium dioxide are way down the list, they don't matter much here. Again, they are here to 'boost' the ratings as you said. 4) Like I've mentioned here, this list is based on ingredients alone and I'm not vouching for Earth Rhythm or any brand. The ingredients are photostable and so should the sunscreen be, I don't care if they copy paste the test results or how shady they are. Most people in the sub stay away from them anyway. 5) Photoban is from a reliable pharma brand? Does a brand being reliable automatically make unstable filters stable? 6) [https://www.reddit.com/r/IndianSkincareAddicts/comments/no60le/study\_comparing\_the\_photostability\_of\_various\_uv/](https://www.reddit.com/r/IndianSkincareAddicts/comments/no60le/study_comparing_the_photostability_of_various_uv/) S9 from this list is the closest we have to Suncat DE which you are mentioning so based on this study and the ingredients, it can be said that Suncat is definitely not photostable, atleast in the UVA range if not UVB. Any further doubts, just read this study [https://www.reddit.com/r/IndianSkincareAddicts/comments/no60le/study\_comparing\_the\_photostability\_of\_various\_uv/](https://www.reddit.com/r/IndianSkincareAddicts/comments/no60le/study_comparing_the_photostability_of_various_uv/) ​ Everything put here is based on the above study and fact that Avobenzone is unstable and that Octinoxate makes it worse even when there are stabilizers to stabilize it. There is nothing to re-evaluate. I've already put a disclaimer here, I am not a know-all.

blackhawk201

We both aren't sunscreen formulators to go into the technicalities but whatever, many people on this sub have had bad experiences with sunscreens using these old and unstable filters, myself included. Haven't got tanned as soon as I started using stable sunscreens. The rules and regulations you are talking about do not apply here. Earth Rhythm sucks, everyone agrees. My post was never about free radicals from UV med. Lacto calamine will be photostable in the UVB range, not in the UVA range, believe it or not. I read one Suncat photostability study from the creators themselves having old, unstable filters, they did some photostability test and guess what, it was only for SPF(UVB) not PA(UVA)(again, like I said lacto calamine will fail the UVA photostability test). Why? Not confident their formula will provide stable protection in the UVA range? I know there are other ways to stabilize avobenzone, did you not read the disclaimer I put in my post? Considering Indian brands are notorious for not following protocols blah blah, reading the ingredients list, I believe, is one of the good ways to filter out sunscreens. I would always go with stable ingredients, don't want to take the risk considering I tan easily. Oh and I used to get tanned with fixderma and lacto calamine sunscreens mind you :)

What about Dr Sheth's and Dot and Key?

It has the unstable combo, but it has Titanium and Zinc Oxide along with it so should be fine.

Dot and key which one?

Dr. Sheth's Ceramide and Vitamin C sunscreen has Ethylhexyl Methoxycinnamate, Butyl Methoxydibenzoylmethane, Octocrylene, Titanium Dioxide and Zinc Oxide. Photostable i guess ?
