Retin-A comes in different strengths. I use 0.025% and the cream, not the gel.
There is a prescription-strength Retinol version that is weaker than Retin-A but still stronger than the OTC stuff, from what I understand.
Insurance pays more for the generic version, which works just fine with me. The generic name is tretinoin.
I stopped using any facial scrubs because I use the cream pretty much nightly, so my face can't take any more abrasion without showing it. Moisturizing is now essential because it is drying.
It also cleared off some old acne marks and changes in pigmentation as well as decreasing the wrinkles.
