Understanding How Laser Treatment Works for Acne Scars
Acne doesn't always leave scars, but habits like picking, scratching, and squeezing can cause lasting damage. Fortunately, laser treatment offers an effective way to reduce the appearance of these scars.
Types of Laser Treatments
There are two main types of lasers used for treating depressed acne scars: ablative (resurfacing) and non-ablative.
Ablative Lasers
Ablative lasers are traditional yet aggressive options. They work by removing the outer layers of skin, burning away scar tissue and prompting dermal collagen to tighten. This process effectively reduces scar visibility. However, it leaves the skin red, sensitive, and painful during the healing period, which can take several months to a year. Proper care, including soaks, antibiotic ointment, and dressings, is essential to prevent infection. The skin that regenerates is usually free of scars and wrinkles. The ultrapulsed carbon dioxide laser and erbium YAG laser are commonly used in this method.
Non-Ablative Lasers
Non-ablative lasers do not harm the skin's outer layer. Instead, they stimulate collagen growth to reduce scar appearance. Unlike ablative lasers, non-ablative treatments require multiple sessions. One popular FDA-approved option is the Smoothbeam laser, which targets and heats sebaceous glands to reduce sebum production, a factor in acne formation. The heating effect tightens the dermis, minimizing scarring.
Treating Raised Acne Scars
Raised scars, such as keloids and hypertrophic scars, require a different approach with pulsed dye lasers (PDL). PDL reduces itchiness, pain, discoloration, and scar elevation. It uses focused beams of light to target blood vessels, converting light into heat to destroy these vessels without harming surrounding skin. PDL is safe, using yellow light to avoid long-term damage. Sessions take just a few minutes, usually without anesthesia, and multiple appointments may be needed. Bruising is a common side effect but usually clears in 3-10 days. Temporary pigment changes may occur but typically resolve within a few weeks. To minimize side effects, apply sunblock at least one month before treatment, as tanned skin can interfere with the laser's effectiveness.
