- The chemists are gearing up for their 30 for 30 sunscreen challenge test! So naturally this is a great time to check up on some of the latest studies on sunscreens. We cover a large survey study on people’s sunscreen application habits (spoiler alert: it’s not great), an oil based vs water based cleanser study on sunscreen removal, a new J&J SPF50 vs SPF100 study, and an update on the ongoing studies on sunscreen’s impact on coral reef.

Controversy Corner: do we absorb sunscreen into our bloodstream?

On the bright side : This is the one time (sunscreen application) where I actually feel part of a microscopic elite club. 😂
💪💪💪
I love animal fun facts corner! I always learn something new
one of our favorite segments too 🥰
This was SUCH a great and informative video!! I found the study on sunscreen habits extremely interesting!
Wohoo!🎉 congrats! Love your scientific ethos and great sense of humor!
haha always happy to hear our weird sense of humor resonates with someone 😆😆
In Europe we have oil based shower gels - aka. shower oils - for dry skin... And no one knows that those are very similar to makeup remover cleansing oils, and the best and most convenient products to get rid of body sunscreens.
ohh i do love those shower oils, super luxurious and very convenient post beach day :)
Very cool to see the visuals of regular vs oil cleanser on water resistant sunscreen. It’s been a question on my mind whether I should be double cleansing. It helps to know that sunscreen also degrades after two hours such as by sweat or water. Perhaps oil cleansing is not a big necessity? Except for tinted sunscreen
I'm sure I would use redness as a signal for reapplication, that's common sense. In my interpretation the opposite of that would mean ignoring redness as a signal, so I would definitely answer "yes" to that question.
After much trial, my skin couldn't handle a double cleanse (oil/balm). I even tried micellar water and it irritated my Atopic Dermatitis prone skin. Now I use a mild foaming cleanser, Neutrogena Hydroboost, and find that it does remove all my waterproof sunscreen. I do try to clean for 30+ seconds. But I'm still a little hesitant if it is truly removing all the sunscreen... :/
in our experience, amount of time you take to lather definitely improves how thoroughly it cleans by leaps and bounds. I wouldn't worry too much! Not irritating skin should be the top priority
Interesting about mineral sunscreen re: coral reefs. I do recall at least one scientist saying if people were concerned about that they should stick to mineral sunscreens and UPF swimwear. If someone didn't want to use a cleansing oil/balm, they could just double cleanse with their regular cleanser to remove that sunscreen, right?
if you clean twice with your regular cleanser, it''ll definitely remove most sunscreen. Some tinted ones though... super extra stubborn and really takes an oil cleanser to loosen it up
Re the OTC remark, I've even seen derm influencers use OTC to describe retinols and other skincare products
sighhhhhhhhh 😵😵 that definitely doesn't help with the confusion...
As someone with melasma, I use at least an SPF 50 & PA++++, daily, in the morning. As I work indoors (no windows) and wear foundation, I do not reapply sunscreen. But, especially on the drive home, about 20 minutes, I feel guilty. I live in Maine and the sun is not a huge issue, except in the summer. I always double cleanse with a balm/oil and a milk cleanser, as I have dry skin.
Dear chemists, what are the most elegant body sunscreens you can recommend? I find body sunscreens really difficult when it comes to everyday during the summer because so many of them feel disgusting and get all over my clothes and car (I’m autistic so the sensory sensitivities are major)
How do you feel about a mousse texture? I really like the Evy Technology sunscreen for the body, It’s a staple for me and family in the summer time and has really high protection.
Hope that helps! 🙂
@@maddy3562 I’ve been very interested in trying the Evy mousse but I live in the US and it’s very difficult to get it here. I know that ifsogo ships to the US but they require a minimum of six cans so I’m trying to get some of my parents’ Swedish neighbors to pick up two cans for me while they’re visiting back home so I can try it before blind-buying the ifsogo minimum amount
I wonder what percentage of the population have or have had skin cancer, and thus have a very different usage profile?
that's a good question... this paper didn't survey for skin cancer in particular 🤔🤔
