I have used Retin A for years...off and on...sometimes years before stopping and applying again.......it will thin your skin and it will cause your skin to sag more as you are older.....I wish I had known. My skin looks good for my age they tell me but I am started to sag some and I know it was the Retin A.......it can also harm a persons liver. Just beware.....
