Dermabrasion is a method of mechanically exfoliating the outer layers of skin using a rotating device. It is a procedure that uses a mechanical device to remove the upper layer of skin and reveal new skin. Dermabrasion is usually performed on the face by a plastic surgeon, dermatologist, or other aesthetic provider.
Microneedling is a treatment in which a dermatologist creates multiple tiny puncture wounds in the skin with sterile microneedles. The physical trauma triggers the body's natural healing processes. This encourages the deeper layers of the skin to start regenerating and rebuilding, leading to the creation of new tissue. This, in turn, leads to rejuvenation and helps correct many common skin problems.
