Silkpeel is a brand of microdermabrasion where small crystals are used to "sand blast" the surface of your skin essentially removing part of your top layer or epidermis. Dermabrasion uses a diamond burr or fraise to remove the top layer and part of the bottom layer of your skin. Regular dermabrasion has a longer down time but better results.
All the best,
