Retin A starts out harsh. I had 3 weeks of redness and peeling and my dermatologist had me switch to applying every other night. If you can stand the redness and peeling, it's absolutely worth it. I used Retin A and tetracycline for 4 years but after awhile I just needed the Retin A.
I no longer have acne. But as a result of 10 years of applying it, my skin's texture is amazing. Some women pay out of pocket for Retin A because it's also anti-wrinkle, texture-smoothing, and age spot reducing.
So stick with the Retin A for acne. When your acne is gone, stick with Retin A as an anti-aging regimen.
My dermatologist told me that Retin A Micro is the best. No generic and no other Retin A brands provide the same benefits.
