I have been researching glycolic peels and wonder if it will work for me. I want to use it on my chest. I lost some weight and my breast skin must not be that elastic because now my skin on the tops are not firm, in the cleavage area. I'm wondering if I do a glycolic peel if the new skin that grows will be firmer and tighter? I plan on taking vitamin C and MSM as recommended for new collagen growth. I'm just wondering what % of peel to use?
