Is it already too late for me to take retinol, you know, this far into my chopped unk era?

So part of the answer is you don't ever need these things.

You're a beautiful person, whatever, but when you start to see the visible signs of aging, so for a lot of people, that's in their mid-30s, say, they start to see some of these effects.

It depends on how well you take care of your skin and what your standards are.

Mm-hmm.

Because part of what retinol and retinoic acid, what all these are doing, is stimulating the process by which the skin refreshes itself from underneath.
