Are there any members who are using tretinoin (Stiva, Acnetina) cream?

A few years ago and these days as well

It's a cream that ruins dermatology.

Stiva A cream and Acnetin A cream, tretinoin ointments, were popular.

Actually, I tried it myself, but I didn't really notice much of a difference.

Are there any members of the Cashdoc community who have experienced noticeable effects?
