Which method is commonly employed to treat acne scars?

Laser resurfacing is commonly employed to treat acne scars because it utilizes focused laser light to remove damaged skin layer by layer, promoting collagen production and skin regeneration. This process can significantly improve the texture and appearance of acne scars, whether they are atrophic (depressed) or hypertrophic (raised). The precision of laser treatment allows for targeted therapy, which can lead to more effective results compared to other methods that may not directly address the underlying issues of scarring.

Other methods, while beneficial for different conditions or uses, do not specifically target the structural imperfections associated with acne scars in the same way. Topical antibiotics can help manage active acne but do not improve scar appearance. Cold compresses may provide temporary relief from inflammation but do not affect scar formation. Microdermabrasion can improve skin texture and reduce scarring to some extent but is often less effective than laser resurfacing for deeper scars. Therefore, laser resurfacing is typically considered the most effective treatment option for acne scars.
