Chemical Peels for Acne Scars

Chemical peels help to get rid of acne scars and discoloration caused by acne by slightly damaging varying layers of the skin and promoting new tissue growth. When the skin is subjected to the damaging effects of acne, the body’s natural healing process replaces the damaged tissue with a collagen protein.

Although this protein also makes up normal skin, the fibers in the collagen of an acne scar are woven together differently that those which make up a healthy skin layer. This causes the acne scar to appear different than the surrounding skin in color and in texture. There are four types of acne scars that chemical peels may be able to get rid of.

Hypertrophic scars occur when too much collagen forms in one place; the scar tissue can be raised above the surface layer of skin. Ice pick scars are more common, and are “v” shaped pits in the skin. Box car acne scars are squared pits and rolling acne scars are rounded pits. Pits form because the collagen tissue is embedded deep within the pore and beneath the surface of the skin. As the wound heals, the top layer of scar tissue is pulled downward, toward the original site of the skin damage within the pore.


How Chemical Peels Get Rid of Acne Scars


Chemical peels use one of several chemicals to get rid of acne scars. Each type of chemical works at a different level of the dermis. Surface scars (those which rise above the surface of the skin) and acne scar pits may be treated with glycolic acid. Glycolic acid is commonly used for acne, while deeper chemical peels are sued for other skin conditions; including wrinkles, sun damage, precancerous spots, and some types of skin discolorations. (Skin discoloration may be caused by acne, as well.)

Chemical peels allow doctors to damage the skin under extremely controlled circumstances. By applying a chemical to a very specific point on the skin, that part of the skin becomes damaged. Following the chemical peel procedure to get rid of the acne scars, there is a wait period during which the skin attempts to repair itself. This healing process can eliminate the appearance of acne scars over time.

It may be necessary to undergo several chemical peel treatments to get rid of acne scar appearance. However, in nearly all cases, acne scars are permanent and can never be completely removed. Many acne scar treatments are very effective at drastically improving the appearance of the skin, so individuals should talk with a doctor about the right type of treatment for their skin type and scars.

People with severe cystic acne may not be eligible for chemical peel treatments because it is not recommended to use chemicals on an infection. Therefore, chemical peels are not usually used to get rid of acne scars in people with ongoing cystic acne. A type of acne treatment medication known as Accutane can also disqualify an individual for this type of acne scar treatment.
