What is the Difference between Microdermabrasion and Dermabrasion?
Cosmetic Microdermabrasion has no major side effects and the treatment of the skin isn’t as deep as medical dermabrasion, which also “abrades” deeper skin layers. Scars are better treated with a medical dermabrasion as they often lie in a deeper skin layer. However, dermabrasion also involves risks, as it can lead to the typical point-shaped skin bleeding and permanent scars. Aesthetics can also deteriorate due to dermabrasion, in contrast to cosmetic microdermabrasion, which is more gentle on the skin.
