Acne marks, i.e. inflammatory pigmentation left after acne healing, are now commonly used treatments, including laser treatment, gold micro-needling, fruit acid peeling and so on. 1. Laser treatment: The photothermal effect of laser promotes the absorption and metabolism of pigment particles, and at the same time stimulates the regeneration and rearrangement of collagen fibers and elastic fibers in the dermis, which can lighten the pigmentation and improve the condition of the skin, and it generally requires multiple treatments. 2. Gold micro-needle: gold micro-needle through the skin caused by a small incision, stimulate the skin collagen regeneration, to achieve the effect of repairing acne pits and scars, the treatment is less traumatic, the recovery process requires scientific care. 3. Chemical skin resurfacing: through the use of fruit acid or salicylic acid on the epidermal layer of cell peeling, can achieve the effect of reducing pigmentation, suitable for relatively minor acne pits. There are more medical projects to get rid of acne marks, so it is recommended to choose a regular medical institution and choose the treatment plan by the doctor’s assessment to avoid adverse consequences.
