Use forever: I love tretinoin and think that every non-pregnant person should be using this (until it expires, of course). A small pea sized amount to your entire face at night is recommended. You can use it elsewhere if desired but not overuse as will cause irritation. Works for acne, pigmentation, mild scars, and reversing sun damage. Use the right sunscreen daily and give it 6-9 months for best results.
