Acne marks are post-inflammatory hyperpigmentation and capillary dilation due to the disappearance of acne. The most commonly used method is laser removal, which is less risky and has fewer side effects, generally harmless, and is a safer conventional treatment. If improperly operated, it may produce pain, hyperpigmentation, edema, blisters, scars and other adverse reactions, blisters and scars are less common and closely related to the operator’s technique and experience. Laser treatment uses the instantaneous blasting energy of the laser to break up the pigment of the pimple marks, while the laser can also effectively stimulate the skin collagen regeneration, prompting the pimple pits to restore flatness and achieve more desirable results. The laser treatment of acne marks commonly used non-ablative fractional laser, not break the skin, no crust, no damage to the stratum corneum, the effect is better and safer. It is recommended to go to a regular hospital for laser surgery and pay attention to a light diet after surgery. If you do not pay attention to your diet, it may affect recovery, pigmentation, or even infection and local redness and pain.
