Are retinol cosmetics effective?

A. 1

I asked the dermatologist
There's no effect on just makeup
It's because the content is too small to the point where it's meaningless
If you use a high content, it's too strong, so there will be side effects
If you want to see the real effect, it's meaningful if you apply it for a long time
It takes a long time and costs a lot of money
I heard it's hard for ordinary people to do it'

OK

@1 It's hard to see the effects of makeup because of its functionality
No matter what you use, it's hard to reach the dermis
Basically, the skin is an exhaust organ, not an absorption organ
Functional cosmetics don't have much meaning
