  • Published on Jul 11, 2019
  • A recent F.D.A. study shows that certain chemicals in some sunscreens can seep into and remain in people's blood. To find out what that means for staying safe in the sun, WIRED's Robbie Gonzalez spoke with dermatologist Dr. Kanade Shinkai.

    Funny, minute 8 the lady applying lotion had her sunhat on the ground.

    I only used mineral based sunscreen since this year. It works fine- it’s like that sunscreen you had when you were a kid (super white on your body 😅). But i’m well protected as well as the ocean life - I feel good 🧘🏽‍♀️

    You could always partially aestivate. I can't remember the last time I got sunburnt. The sun is disgusting anyway. I know it grows all the food but it doesn't mean I enjoy it personally.

    This year the FDA gave warning to all Sunscreen manufacturers that NEXT year they would be cracking down on all the chemicals used, that there are NO studies of effects of their long term use. They said you have a year to sell of your current stock then have to remove untested chemicals or we pull it off the shelf.
    The problem is the mineral sunscreens paint you white, and are safe but hard to spread and make you look pastey. The chemical ones are clear, absorb better, feel good going on, moisturize your skin etc. So you have to suffer for health, smh.
    New method I saw on vacation recently was wearing long sleeve and long pants wetsuit like outfits. Just cover your body as much as possible so the sun cant hit you.

    Don't forget sunscreen slows down wrinkles and skin aging. Even in cold or cloudy days, UV rays still break through are the number one thing that ages your skin, most straight men don't seem to like using it which is why they age quicker.

    My bet is that those companies made their studies a long time ago and they were hoping FDA will not request them for as long as possible 🧐😂

    These big chemical companies are the worst. They lobbied so that all the chemicals they already used for some years, possibly decades, should not be tested, because we would know if its dangerous. The problem is, that its not true. They just showed that talcum can make ovarian cancer, and talcum companies knew about it:

    There are sunscreens out there that aren’t harmfull for coral reefs that also don’t have harmfull chemicals.

    Sun screen prevents squamous and nasal cell cancers, nothing for melanoma except Zinc oxide. Sun screen makes it able for you to stay in the sun longer without the natural warnings of a sun burn. This increases your chance of Melanoma

    The mineral sunscreens are significantly more expensive than the chemical sunscreen in Australia, so there is a big price difference.

  • Gaasyendietha

    I’ve been asking myself those questions for a lot of cosmetic products. We can’t assume to put product on our skin that contain chemicals on a daily basis and no side effect on our health whatsoever.

    It’s really very simple. We don’t know if those chemicals are harmful to our bodies. Clearly the companies in question are not making the necessary testing their top priority, so guess what; pulling their products off the market IS NOT an extreme measure. Let’s save politics for the congress. Doctors (and any public service provider) best interest is with their patients and not with big companies. There is enough probable cause to think they are not acting in good faith

    How about a study on how well the sunscreen works. As a ginger I burst into flames in the summer sun. I had on sunscreen when I went to the pool and still burned

    😕 Damned if we do, Damned if we don't. A Hobson's choice. A rock and a hard place. A dither and a quandary. Everything is a Kobayashi Maru scenario. Up Sh*t Creek without a paddle. A lose/lose scenario. Can't win, can't break even. FOL. SOL. Deal with the devil. Shoulda done this, shoulda done that. Too late for apologies.

    why test on animals... if people are already wearing sunscreen, why not check the levels of it on humans?
    if i ever have a kid, i give him a breathable shirt on, as for myself don’t stay in sunlight too long

    I love how they break down the study. I've browsed through many papers and often times I encounter ideas/terms I don't recognize since I was not a science major. I just check if I can use them for reference material. It's also good to know if the people on TV are just spinning lies off of a study or if the study itself is not credible.

    Can everyone just go to this point in the video and listen to that a few times. That's how weak the FDA is.

  • agaragar21

    "Harmful unless proven otherwise", that's the correct safety standard !........Today's totally risky attitude by scientists and government are not honest or sensible !

    for example a huge part of human genome is being affected by something and a logarithmic increase of Autism diagnoses is taking place

    When i was a kid, in the 1970's, a whole year would go by without me witnessing a single person with autism, now i see several every day !

    The interviewee is lying, there is no onus on anybody for anything!

    Just dont use sun screen then, gradually build up a base tan like me, then just do 45 mins to an hour tops.
    Never burned or peeled and I'm 50 now, i use palmers coco butter to keep moisturised, now golden brown all over.

    This is the worst “Let’s make things clear” public health announcement ever. It ranks up there with the 1950’s nuclear energy ads. Hmmm, Better Living Through Chemistry?

    Conclusions: Smearing chemicals onto your skin (which is a permeable filtration organ) is perfectly safe (come on, everything is technically a chemical anyway ;) probably, maybe, we don’t know, sure go for it, what is the worst thing that could happen? Put it on your baby! Put it on your wife! Put it on your grandma! Just don’t go into the ocean-we do know it kills coral reefs (permeable filtration systems of the oceans) and most likely other animals too. Happy sunning!

    Great interview and praticable questions. It's hard to imagine that we have chemical sunscreen for so long and we don't have the data of those 4 chemical absorption into our bloodstream. Based on the way she respond, I have the feeling she cannot say what she already know. The sunscreen Lobby must be pretty worried about the outcome of the study.

    Oh no. Now they are trying to get people to stop wearing sunscreen because they want to kill people off with skin cancer. People protect your skin against the sun at all cost. Find something natural if you you have to

    An interviewer that is actually smart and understands the topic?? And an interviewee that is well-spoken?? I never though I'd see the day. Usually the interviewer is just a good speaker and the interviewee, smart but can't get thoughts across properly.
