Does Sunscreen Cause or Prevent Skin Cancer?

I hope Dr Greger will cover chemical vs mineral sunscreens.

I'm going to say this once again: SUN CLOTHING works great. It's obvious where it is applied, it doesn't wear off--but may ride up. It starts/stops working immediately. And is very economical (can be purchased second-hand from many sources). It can also be used in conjunction with whatever SPF spray/lotion/creme you like for areas of exposure. AND after the sun gets low in the sky, you can take it all off-as desired.

Hey, we want to know if the ingredients in sunscreen causes cancer,. We all know sunscreen prevents skin cancer. That is the crux of it, are you replacing one cancer for the other with the use of sunscreen.

Our bodies are miraculous. Just give it the smallest protection against harm, and it starts healing itself!!!

What about toxicity of sunscreen? Is there any concern?

Hello. This is very interesting, but can you please follow it up with something concerning the relationship between sunscreen and vitamin D production? Thank you!

I wear UPF clothing every time I go outside. It saves me a ton of time & money. I’ll usually only put sunscreen on my face

Then there's people like me - who have had one basal cell carcinoma. I put on sunblock all the time when I was a kid. Must have been the sunblock, right? Couldn't have possibly been the family history of skin cancer I have, or the very large amounts of time I spent in the sun, in the desert Southwest, as a kid. And oh yeah, I didn't cover up, and didn't always apply sunscreen regularly or enough - I recall plenty of very deep burns. So as an adult, I cover up as much as possible, after putting sunscreen on my face, neck and hands - sometimes I have to uncover my my face or hands while outside. But I got a hat with back and side covers and front covers, albeit the front cover is partly mesh. But the brim and sunscreen helps. Also stopping in the shade or at least turning my back to the sun.

Thank you for changing my life.

"Recent experimental studies have shown that sunscreen remains on the skin at the desired SPF for as long as 8 hours after a single application" ☺

Thank you

I love this channel!

Thank you! You answered a lot of the questions I had been wondering about. Excellent video and I like that it was not excessively long. Again, thanks.

Thank you! Very helpful!

Dearest Dr Greger, as much as I have huge respect for your work, it is important to differentiate the various types of skin cancer and the relationship with sun exposure. SCC and BCC (and the precancerous actinic keratosis) that you mention in the studies behave very differently from Melanoma, which is the really malignant skin cancer. Can you please refer to studies that put to the test the risk of Melanoma with sun exposure and not the other locally aggressive (but not metastasizing) skin cancers? Can you also comment on the fact that Melanoma can develop in parts of the skin that are hardly exposed to sun? On the other hand, the risk from the lack of sun exposure to the overall health can be detrimental and I am glad to see that many people are asking you about this.

Great video, thank you. I’m glad I found your channel

I live in New Zealand, and the sun is incredibly strong here. Fun fact, the sun is closer to the earth in the southern hemisphere, compared to the northern hemisphere (during summers). Sun protection is crucial here. I really enjoy these videos on sun protection. Thank you.

Thank you♥️

Thank you so very much <3 so important!
