Principle of dermabrasion:
Micro-dermabrasion operates on the premise that encouraging exfoliation of the skin is desirable. The word “micro” is used to separate this procedure from true dermabrasion,where the deeper layers of the skin are removed. By using a motorized brush system or bombarding the skin with high-speed particles, it is possible to remove desquamating corneocytes, and make the skin smoother and softer with a better color.
It is important not to go any deeper into the skin than the first few layers of stratum corneum to avoid scarring and other problems. Microdermabrasion can be used by trained skin care professionals because it does not enter the living layers of the skin;
any procedure that enters the living layers of the skin and causes bleeding should be performed by a physician.
