Light Treatment for Acne Scars


Acne scars are unique to the individual, so treatment often varies from person to person. What improves the appearance of one person's scars might not do anything to better your own, so it's best to consult with a dermatologist to establish the appropriate treatment plan. One of the emerging treatments for acne scars is light therapy.


Doctors use light therapy more often to treat acne than to improve the appearance of acne scars. The bacteria associated with this skin condition contain molecules that are photosensitive, according to the American Academy of Dermatology. When the skin is exposed to pulses of light, the bacteria absorb the energy, which increases the internal temperature and causes them to burst. This aids in recovery and thereby improves your complexion. Light therapy reduces oil production, which can decrease bacterial buildup and prevent the clogging of your pores.


Untreated acne, especially severe acne, is more likely to cause permanent scarring, according to the American Academy of Dermatology. In this regard, light therapy is a preventive measure to avoid acne scars. However, light therapy also can help reduce the appearance of acne scars already affecting the skin.


Exposing acne-scarred skin to waves of light energy can stimulate the production of collagen under the epidermis, or the surface layer of your skin. Collagen is a protein that provides plumpness to the skin. With the additional collagen production, the irregular areas of the skin begin to take on a similar appearance to the rest of your skin, making scars less visible.


With light therapy, it can take several sessions to provide visible improvements to acne scars. But the real advantage with light therapy is its ability to treat not only scarring but also acne, so it's an ideal option for people suffering from active acne and acne scars, according to the Mayo Clinic.

Expert Insight

Deeper acne scars often benefit from a combination of light therapy and soft tissue fillers, according to the American Academy of Dermatology. Improvements are generally subtle with light therapy alone, so treatment doesn't always provide the desired results. Injections of hyaluronic acid, collagen or fat after light therapy can better even out pockmarks with the rest of you skin.
