Microdermabrasion has minimal impact on acne scars! Why? It’s because acne scars lie in the deeper layers of the skin called the dermal layers. Microdermabrasion can temporarily smoothen the upper most layers of the skin called the stratum corneum, and may create an illusion of scar improvement. Results if any, are temporary. Specialists recommend Glycolic AHA peels ahead of Microdermabrasion as peels are more cost effective, quicker to perform but most importantly, more effective than Microdermabrasion.
