Re: Facial aging

I understand your points and agree with most of them. However, I think UV radiation—especially UVA, which is not effectively blocked by most sunscreens—does play a large role in what we perceive as an aged appearance.

For the sake of discussion, say someone wore an opaque mask or sunblock every time they went outside during their entire life, including childhood. I claim that, at age 60, such a person’s skin would likely appear to be 40—or less.
