How Does Laser Acne Scar Removal Work?


Quick Answer

According to WebMD, laser resurfacing for acne scar removal is a procedure in which a high-energy laser is utilized to remove one layer of skin at a time. The laser emits pulsated light that creates heat when it comes in contact with the skin, eradicating the tissue. Once the affected tissue is removed, healthy skin cells grow back in its place, creating a smooth surface that is free of scars.

The American Society for Dermatologic Surgery explains that a topical anesthetic solution is usually applied to small areas of skin prior to a laser scar removal procedure to help minimize pain. Larger procedures may require sedation or nerve-blocking medications. The healing period following a laser treatment ranges between three and 10 days.

According to Mayo Clinic, side effects of laser acne scar treatments can include itching, inflammation and swelling of the treated area. Ointments applied to the skin following treatment may cause additional acne to develop. Laser resurfacing treatments may also cause hyperpigmentation, a condition in which the treated skin becomes darkened. Hyperpigmentation is most common in individuals with darker skin tones. The condition is often temporary and can be treated with topical acid ointments. Laser acne scar removal treatments are usually not recommended for individuals who are pregnant or those who have taken oral acne medications for the past 12 months.
