Beauty Tips For Body Care
Been using it for about 3 weeks and have only seen minor improvement. Mainly i am trying to diminish scars (possibly some hyper pigmentation). I'm really just trying to get skin as close to perfect as possible. I also have a bunch of little bumps on my forehead (not acne - apparently it is sun damage).Any tips are appreciated.
