The Single Most Important Thing for Anti-Aging Skin Care

There is nothing more important to slow the facial signs of aging than to protect your skin from the sun. Sunscreen is put to the test in a randomized controlled trial to see if it can actually slow skin aging.

Spoiler alert: The single most important thing? Wear sunscreen. The next two videos go into more detail: Does Sunscreen Cause or Prevent Skin Cancer? ( ) and The Best Type of Sunscreen to Use ( ).

I did a lot of research on skin aging for my new book, How Not to Age ( ). Some of that research has also come out in videos:
• What Is the Most Important Anti-Aging Cream Ingredient? ( )
• Topical Retinoids to Reverse Skin Aging ( )
• The Benefits of Topical Niacinamide for Reversing Skin Aging ( )
• The Benefits of Topical Vitamin C for Reversing Skin Aging ( )
• The Efficacy, Safety, and Side Effects of Botox and Facelifts ( )
• The Efficacy and Safety of Fillers, Chemical Peels, and Laser Skin Resurfacing ( )
• What Causes Wrinkles? ( )

I also recently answered the question whether Collagen Supplements Work for Skin Aging ( ).

    I believe this…I always wore makeup with spf and was told it wasn’t enough, didn’t do anything, well, let me tell you…every little bit helps. Now I use spf under makeup and in makeup, and sunglasses.

  • @JoshBender1 says:

    Reminds me of a song… Wear sunscreen. 😊

  • @wadepatton2433 says:

    I wear a wide-hat and long sleeves every day, plus sunscreen on my hands and face on bright days, also polarized glasses any time the sun is shining or the clouds are bright. I work outdoors year around-I wish I’d taken these measures as younger person. I started seeing the sun damage on my skin 10-15 years ago. I’m 57 now.
    I only take off the long-sleeves/roll-up after 4pm. Sleeves at the beach too. They now make brim extenders for hard hats (when I need to wear one of those). Shade is the ticket.
    You want to hear the odd part: ALL the Mexican guys/gals working on these jobs use long sleeves and big hats to protect their darker-than-mine skin. NONE (very few) of the guys with skin light as mine (Scottish origins) use any protection at all, some go sleeveless, some don’t wear hats, some don’t wear sunglasses–These folks will pay.

      This is great. However sunscreen should also be applied on non bright days aka cloudy days. Uva penetrates through clouds and windows

    • @yogiyoda says:

      Terrible advice. Increased sun exposure is strongly correlated with decreased all-cause mortality. Look up the studies yourself. Don’t get burned. But try to get consistent moderate sunlight daily if possible. Sunlight exposure benefits go beyond increased vitamin D levels as well. Following Dr Greger’s advice on protein and sun exposure will make you unhappy, pasty and weak. It’s no coincidence that all the blue zones are in areas with plentiful sun exposure

    • @Maggie-zr2ow says:

      Maybe consider sun protective clothing. I’ve read that cotton only protects only a little and you still get a lot of exposure through the clothing. There are some great companies that only make sun protective clothing and you can do layers or just a long sleeve over a regular t-shirt, and of course full length pants.

    • @wadepatton2433 says:

      not–OMG never in this humidity- cotton.

    • @mariabonita423 says:

      What about your vitaD? Moderated sun exposure is cancer protective too

  • @sherizarn says:

    Please give guidance on what sunscreen to use. It’s hard to find one that doesn’t have bad chemicals. I find mine on the EWG app, but it takes a long time and the one I used last year didn’t seem to give much sun protection.

    • @21972012145525 says:

      Ignore ewg and their scare tactics on ingredients.Dr dray recommends many sunscreens on her channel. Her advice is to find the sunscreen you enjoy using and applying

    • @adamlee3333 says:

      I highly recommend zinc oxide mineral sunscreen (SPF50), it stays on even in water and I find I actually enjoy putting it on, compared to the ‘chemical’ sunscreens which never worked for me OR I was allergic lol, but always ended up red

    • @oneheart19 says:

      @@adamlee3333 I was going to say the same! A key ingredient, according to my dermatologist, is the zinc oxide. The actual brand I found and like is Seaweed Bath SPF50 at Natural Grocers.

  • @efivos5362 says:

    01:56 We need some clarification on the NIR wavelengths that cause skin aging, because research in photobiomodulation indicate that NIR wavelengths of up tp 850nm promote skin health, reverse aging, reverse wrinkles, etc.

    • @Anacaonas_Flowers says:

      I was thinking the same thing

    • @21972012145525 says:

      It is my understanding that “red light” is different than NIR? Interested in learning more though. However, imo it doesn’t change the basic premise: sunscreen!

    • @xcast1 says:

      Wonder the same. Red/NIR light photons cannot directly break the normal biochemical bonds – unless in tricky combinations made for photosynthesis, retinal sensing etc.
      Maybe some effect via thermal heat by high intensities.

    @Dr.Greger I am interested, if there was a difference in the incidence of skin cancer in both groups. Thanks!

  • @jefflebowski918 says:

    The general rule for safe sun exposure that will produce Vitamin D:
    Light complexion – 15 minutes
    Medium complexion – 30 minutes
    Dark complexion – 60 minutes

    Vitamin D is produced by UVB rays which are available outdoors between 10am – 2 pm. UVA rays cause the most skin damage and can penetrate glass.

  • @madamecurious says:

    I started using parasols, they also protect a little from the heat here in Florida 🌴☀️

  • @serisingh says:

    It’s unfortunate that reducing sun exposure prevents signs of aging. Because Sun exposure seems to be the only thing that keeps my acne at bay. And I already use prescription topicals like tretanoin!

  • @angrycrypto465 says:

    So, as an FBA only thing I notice living mostly in Houston and walking in the sun 2 to 3 hours daily, plus doing track and field practice in the sun 1 to 2 hours 2 to 4 days per week is that my skin is darker. Albeit, I was in DFW in 2020 and Houston since 2021 and Houston is much hotter.

    Could be humidity that’s the factor?

    I only got sunburnt once in my life and that was in DFW pre-walking daily 2 to 3 hours. I had almost fainted, was dehydrated and soccer player gave me water. Was so out of it, I couldnt even go faster than a slow walk before my vision darkened and feeling lightheaded that day.

    Since then, all I did was slowly ramp up my exposure to the sun. I purposely do my training during the hottest part of the day, since my competition could be during that time. Otherwise, walking is random, like going to the store instead of driving or catching a bus.

    Just sharing my thoughts

  • @JDJDIDNDKDK says:

    my skin secret is beta carotene eating loads of raw greens and carrots, and also avoiding monosaccharides including fruit and high carb grains/starches as well, and also avoiding salt, alcohol and caffeine. And equally important as what goes in, is getting it out the other end efficiently/ sufficiently.

  • @paulcohen6727 says:

    I’ve gotten badly burned while wearing sunscreen. So instead, I started taking polypodium leucotomos capsules daily, adversely as a kind of oral sunscreen . I also found one study indicating that it fights skin cancer. After taking it for a year or so and not getting sunburned, I also realized that the actinic keratosis on my hands had disappeared in spite of continued sun exposure

  • @lint8391 says:

    My mum’s been saying that the sun ages the skin for 50 years. I’m glad I’ve sort of partially followed her advice.

    I use titanium dioxide and zinc oxide as white pigment on my linseed paint that I use on the external 140 year old oak window frames.
    Maybe I should paint myself with this, whenever I go out on sunny days?
