"Everything is a chemical. Let's start there." YES!!!

[@candicefoy]

And some chemicals are toxic / endocrine disruptors, some are not. I don’t understand why everyone is now trusting cosmetic chemists on how chemicals affect the human body. The reality is research has now shown that the specific chemicals in sunscreen do enter the body AND do act as endocrine disrupters. The second reality is chemical sunscreens make up such a huge market that the FDA has allowed them to continue selling products until further research is done, by the chemical sunscreen market lol. We know how this goes…

[@jacobaeden]

the way ramon needs to repeat "everything is chemical" several times goes to show a lot of ppl did not listen in school and kept going the "natural" route/remedies

[@onlyscience28]

Excellent explanation while debunking the misinformation out there. Thank you, Ramon, to me science based knowledge is the key to making informed choices in every aspect of our life and your expertise makes it possible

[@RabbitinCanada]

[@ajamesu]

Bust those myths, Ramón! These are some great ones

[@amazingme88]

I literally NEEDED this video today ❤🎉 thank you Ramon

[@yasmini8038]

There is a spf50 sunscreen made with mineral and I kid you not it applies like aloe Vera gel - zero white cast. It’s called the FWBeauty mineral sunscreen. I’m even doubting if it really works.

[@kathleen5800]

[@sup8668]

Does powdering spf decrease it's ability to block uv rays?

[@sup8668]

I’m asking as I have sensory issues with things sticking to my face, so I like powdering my sunscreen so my hair doesn’t just stick to my face

[@shonamoraa]

Amazing video

[@neneg.4264]

Very informative video, thnx!

[@jenta4479]

We need to see white coat Ramon more often

[@Orangejuicess]

Yes! Si, Ramoncito. Me encanta la idea de que enseñes un poquito de ciencia y la química de los productos cosméticos. Amo tu trabajo y a ti como persona. Me emociona y me alegro de tus éxitos personales y profesionales. As a Chinese Latina, I’m so proud of you and happy for you❤ I’ve been following you since your videos out of your apartment in London and coincidentally enough I also used to live in London 😂

[@basakbebitoglu3119]

I always wonder if spf protection still persists when foundation is put on top of it? Are there any studies looking at this?

[@sumlem]

I'm curious about that as well! I work in beauty retail so I thought about some possible factors. I can see how applying makeup immediately after sunscreen might alter its coverage. Makeup with a SPF requires a significant amount in order to get adequate sun protection. I wonder if the type of coverage, amount of product, and tools used affect how makeup without a SPF interacts with the SPF from sunscreen. A lot of foundations contain titanium dioxide for color reasons. I've seen tinted mineral sunscreen and makeup with titanium dioxide recommended for melasma and hyperpigmentation. Dr. Alexis Stephens has mentioned this in videos, specifically for melanin rich skin. People who wear makeup tend to touch their face less, but some do touch ups. Sweat and oil production throughout wear time can break apart makeup and sunscreen. It's not as convenient to properly reapply sunscreen over makeup.

[@emilyjensenius4289]

What about companies like Badger Balm that use uncoated zinc oxide as the only filter? Is uncoated zinc actually dangerous to use in formulas per se or does it depend?

[@genshinF2Play]

if i have moisturizing skincare on my face and i powder over it. does it dry my skin? does it conteract the effects of my skincare? specially that i use hyaluronic acid.

[@RB-mr6cr]

Every day, before going to work I putting two layers of chemical of sunscreen than after 10 minutes I putting on tinted zinc oxide mineral sunscreen for extra protection and coverage.

[@amirrhodesve791]

i use a sunscreen with a high amount of seed oil in it, is this problematic? ive heard different things

[@LaddyAddie]

Ive heard that using blotting papers or powders may soak up/absorb the sunscreen but is it actually true? I want to use blotting paper to remove the oils throughout the day but I don’t want to compromise the protection

[@lianne_5165]

I’m an oily gal, I have the supergoop spf powder brush that I keep in my purse to tame the oil throughout the day

[@MRDEREVKO]

Not a sunscreen question, how can I avoid and get rid of ingrown hairs on my jawline, glycolic acid isn't working!

[@user-eg4ie5ti9q]

Thanks a lot! I do have a question: Can the texture of a sunscreen somehow affect its protection level? I do get a bit of sunburn while using the famous Beauty of Joseon sunscreen, although it's a level 50/PA++++ sunscreen. I never had this issue while using the CosRx Aloe sunscreen, although this one only has PA+++, if I remember correctly. I wonder why this happens? They use different filters for sure, but I also feel like the CosRX is very nice for applying a thick layer to the skin and let it sink in evenly while the BoJ feels more watery and as if it would absorb almost too far into the skin. I always use plenty of product as I'm exposed to the sun/sky - thank god - daily.

[@ljuboblajic4903]

Can European mineral sunscreens with SPF 50 plus and PA 4 pluses but with two oils become practically invisible yet reliable?

[@shaydonovan910]

Is there any merit to the claims that chemical sunscreens absorb into your blood and or disrupt your hormones?

[@memoonasaeed4408]

Hi can u please recommend me a sunscreen that's not overly moisturizing fragrance alcohol essential oils free and can be reapplied without making skin too greasy, I'm on retinoids for acne and I'm unable to get one, tried skin 1004 hyalu cica Which sting on my sensitive areas, purito soft touch was overly moisturizing for me

[@K57939]

I use Anessa Perfect UV Sunscreen Skin Care Milk SPF50+/PA++++. I have oily sensitive reactive skin and this sunscreen is gentle on my skin and I can reapply without looking like a grease ball. However, I have heard some people saying it dries their skin.

[@leonleong9863]

Very informative and scientifically sound. It would be great to know if I could layer a tone up sunscreen and another say BOJ over it. Does that work??

[@lolwhat2628]

Sorry if this is a stupid question but why doesnt makeup on top of the spf disturb the spf if skincare might distrupt it?

[@debrucey]

It does. This is why you should always allow time for your sunscreen to fully set before applying makeup, so the film is as stable as it can be. But you will always lower the spf slightly by applying makeup over it.

[@laynaaa]

There was actually research done how wearing foundation with spf protection included affects sunscreen that's already on the skin. And the conclusion was that it was actually beneficial to wear makeup with spf in the formula on top of sunscreen (compared to people who only wore sunscreen and no make up on top)

[@feefee2]

​@laynaaa good to know. I had been wondering why they were putting spf in makeup when we couldn't use enough to get adequate coverage without it looking a mess. This explains it!

[@genshinF2Play]

i just wanna know why whenever i wear sunscreen, it breaks me out. like im not kidding. im prone to cystic acne, and EVERYTIME i put on my spf 50, i get a very painful bump after a day or 2. and it takesss more than a week to heal.

[@genshinF2Play]

ps: i tried every other brands, avene, la roche, anessa, and so on.

[@Emmie1]

Do you think you could be allergic or sensitive to ingredients in that sunscreen? Do a patch test on a small area of skin on you face like your jawline and monitor that area to see if you are reacting to something in the sunscreen. Take a note of the ingredients and cross reference with ingredients in skincare that works for your to pinpoint the culprit. Are you washing your skin thoroughly at the end of the night? I always have to double cleanse when I wear sunscreen or else my skin gets clogged and turns into zits.

[@feefee2]

I get breakouts with most chemical sunscreens. I switched to mineral and haven't had the issue

[@emmacharlenedostal]

Does a “non nano” zinc formation make it desirable than a nano one?
