I used Retin A for about 7 weeks including my under eye area. After 7 weeks, I woke up one morning with creases/wrinkles under both my eyes that I never had before. I stopped using the Retin A and then used 1% hydrocortisone cream under my eyes for about 2 weeks. It has now been about 4 weeks since I stopped the Retin A and the creases under my eyes are still there.
