I went to a dermatologist for the first time for something else, but when she noticed a few whiteheads on me, she recommended I use Retin A and gave me samples. I was told to use it and to check back in 2 weeks. Retin A left me with acne scars all over my cheeks. A year later they are still there. Will these Retin A acne scars ever fade naturally after a few years? If not, what can I do? Thank you for your help.
