Dermabrasion was developed to improve acne scars, pox marks, and scars from accidents or disease. It’s not effective in treating congenital skin defects, most moles, pigmented birthmarks, or scars caused by burns.
Dermabrasion is generally only safe for people with fair skin. For people with darker skin, dermabrasion can result in scarring or discoloration.
Microdermabrasion works on all skin types and colors. It makes subtle changes, causing no skin color change or scarring. It is not effective for deeper problems such as scars, stretch marks, wrinkles, or deep acne scars.
With microdermabrasion, there is less down time than with dermabrasion. Skin is temporarily pink but fully recovers within 24 hours. It doesn’t require surgery or anesthetics. That may help people who cannot take “down time” for healing.
