Laser treatments can play an important role in managing acne scars by improving skin texture, reducing discoloration, and stimulating collagen production. They are most commonly used after active acne has been brought under control and are selected based on the type of scar, skin type, and individual treatment goals.
Different laser approaches include:
- Fractional ablative lasers: These create tiny columns of controlled injury in the skin while leaving surrounding tissue intact, encouraging collagen remodeling. They can improve the appearance of certain atrophic (depressed) acne scars but typically involve more downtime.
- Fractional non-ablative lasers: These stimulate collagen production with less surface damage than ablative lasers, generally resulting in a shorter recovery period, though multiple sessions may be needed.
- Vascular lasers: These target blood vessels and may help reduce persistent redness associated with acne or healing acne scars.
- Pigment-targeting lasers: In selected cases, these may help improve excess pigmentation left behind after acne, depending on the cause of the discoloration and the person’s skin type.
Potential benefits of laser treatment include:
- Smoother skin texture.
- Reduced visibility of certain depressed acne scars.
- Improvement in skin tone and discoloration.
- Gradual collagen remodeling over several months.
Results often develop over time rather than immediately, and many people benefit from a series of treatment sessions. The degree of improvement varies depending on the scar type, its severity, and the specific laser used.
Laser treatments are frequently combined with other acne scar therapies, such as:
- Microneedling
- Subcision
- Chemical peel
- Dermal fillers
Not all acne scars respond equally well to laser therapy. For example, deep ice-pick scars may require other procedures in addition to laser treatment. A dermatologist can recommend the most appropriate treatment plan based on the scar characteristics, skin type, medical history, and expected recovery time. Sun protection before and after treatment is also important to support healing and reduce the risk of pigment changes.
