Acne marks, the inflammatory pigmentation that remains after acne heals, can be improved by photorejuvenation and fractional CO2 lasers to remove acne marks.
Fractional CO2 laser is used to lighten the pigmentation by evenly punching many tiny holes in the skin, causing subtle thermal damage to the skin and restarting the skin’s damage re-repair process; the laser also has a certain degree of exfoliation to promote the metabolism of the skin.
Photorejuvenation is the use of specific wavelengths of laser light on melanin particles, broken to promote its absorption and metabolism, while photons can also stimulate the regeneration of skin collagen and improve the symptoms of coloration.
Fractional laser is the first choice for treating acne pigmentation in clinical practice because it has obvious treatment effect on pigmentation and scarring left over from acne due to its effect of improving scarring at the same time.
Different degrees of hyperpigmentation have different treatment options; for the treatment of inflammatory hyperpigmentation left after acne healing, there are other clinical options, such as dye laser treatment for red acne marks. Therefore, it is recommended that patients who wish to undergo treatment go to a regular hospital and follow the advice of a specialist to choose an appropriate treatment plan.
