Oh it already is. The preparation h (with biodyne) is fixing my horrible, horrible eye bags with amazing speed. The retin-a is for skin tone, and apparently if you go in direct sunlight while your'e on it your face will burn off because the melanin doesn't work. I went out just for a few minutes today, and my skin does in fact feel a little warm. It's supposed to take 8 weeks to start showing results, with some burning and peeling on the way. Wild, huh 😉
