Working Principle: The Diamond Dermabrasion provided a non-surgical skin refinish procedure, by using sterile diamond heads to abrade or rub off the top skin layer, then Vacuuming out the particles along with any dirt. So, there are two things you should pay special attention to: 1. Do not use the machine too frequency (we recommend using it twice a week), Because your skin doesn't grow that fast. 2. Take special care to protect your polished skin as it is as smooth, delicate and fragile as a baby's. (Especially put on a layer of sunscreen if you want to go out). Microdermabrasion can solve the following skin problems: 1. Rejuvenation of sun damaged skin. 2. Reduce age spots and remove blackhead. 3. Reduce fine lines and wrinkles. 4.Reduce and eliminate large pores. 5. Eliminate blain scar. 6. Microdermabrasion can exfoliate skin, enhance skin permeability of other skin creams and serums.
