OVERVIEW

Most acne blemishes disappear without a trace. However, sometimes when acne heals, a mark is left behind.  In many cases, these marks are temporary pink or brown “shadows” called post inflammatory change. These will eventually fade, though it may take many months. Acne scars are different because they are permanent and frequently worsen with age.

TYPES OF ACNE SCARRING AND CAUSES

Acne scars are either depressed or elevated. Depressed scars occur when inflammation from acne destroys collagen, leaving a pit or a divot. These types of scars are more common on the face, especially the temples, cheeks and chin. Elevated scars occur when the skin creates too much collagen during the healing process.  These scars tend to occur more frequently on the chest and back. They can be small tiny bumps or much larger keloids. 

PREVENTION

The 100% absolute best way to prevent acne scarring is to treat acne, especially deeper, inflamed acne very aggressively with oral medication, such as Accutane. Also, don’t pick at your pimples; picking can cause more inflammation and increase the possibility of infection.    

Seeking the help of a dermatologist is especially important if you know you are prone to scarring (ie you already have scarring from previous acne or you have family members with scarring).

TREATMENT OPTIONS

Acne scarring is difficult to treat and typically takes multiple sessions. It is best to treat acne scars as soon as acne is under good control, rather than waiting to see how things go. For depressed scars, treatments are aimed at restarting the wound-healing process with the goal of increasing collagen production. These treatments include subcision, microneedling, threads, Sculptra, and chemical peels. For elevated scars, treatments include Kenalog (steroid) injections into the scar and laser treatments.
