Will microdermabrasion, dermabrasion or exfoliation help remove acne scars?

No, Maybe, No: Microdermabrasion will have little effect on acne scars, as it is a superficial "buffing" of the skin. You may note a temporary improvement in texture which is not permanent. Dermabrasion can help in some cases of acne scars. However, care must be taken in to avoid hypo/hyperpigmentation and further scarring. It is best used in combination with other treatments. Exfoliation won't help scars.

Dermabrasion is best: Microdermabrasion and any kind of topical exfoliant (technique, scrub, or product) will not yield any visible improvement. Actual tissue removal via dermabrasion, chemical peeling, or laser resurfacing will be needed to create any degree of improvement. None of these techniques can completely remove or eliminate scars, but >50% improvement is possible with expertly-performed surgery. Dr. Tholen.

Dermabrasion - Yes: Dermabrasion, medium/ deep chemical peels and laser resurfacing can help acne scars. The amount of benefit depends on the aggressiveness of the treatment and severity of scarring. Often, multiple treatments are required. Microderm and exfoliation will not help. I hope this information is helpful. Stephen weber, M.D. Lone tree facial plastic surgeon.
