For people with darker skin, dermabrasion can cause scarring or discoloration. Microdermabrasion works on all skin types and colors. It makes subtle changes and doesn't cause changes in skin color or leave scars. It's not effective for deeper problems, such as scars, stretch marks, wrinkles, or deep acne scars.
People who are bothered by hyperpigmentation may choose treatment for dark spots. The dermatologist may recommend one treatment option over another depending on the size and pigmentation of the dark spot. Some of the most common solutions include laser therapy, chemical peels, and microdermabrasion.
