Acne scars are leftover marks from previous breakouts. These can become more noticeable with age once your skin starts to lose collagen, the protein fibers that keep skin smooth and supple. Sun exposure can also make them more noticeable.

But that doesn't mean acne scars are forever. Microdermabrasion is one of several options for scar improvement.

With this procedure, your dermatologist or skin care specialist will use a small handheld device to gently remove the outer layer of your skin (epidermis). This process will reveal the smooth, toned skin underneath.

You can get this treatment from a spa or your dermatologist's office.

Read on to determine whether microdermabrasion is appropriate for your specific acne scars, how much it may cost, potential side effects, and more.
