“Sun ages the skin”

Here’s what you’re really saying:

“I’ve been programmed to fear the sun without context. I don’t know that UV-A, UV-B, infrared, and visible light interact like a symphony, not a single note. I don’t know that progressive exposure builds a tan, strengthening skin the way lifting builds muscle. I don’t know that circadian biology is the master regulator of every anti-aging process, from autophagy to collagen repair. So instead of first principles, I repeat fear slogans as if they were wisdom”

Don’t be a parrot who repeats pre-packaged slogans without understanding the biology underneath

Too many recycle a dermatology marketing script, word for word, without ever digging into the mechanisms, context, or nuance
