The following options are available for the treatment of acne pits: i. Fruit acid treatment. Fruit acid treatment is to reduce the adhesion of keratin-forming cells by interfering with the binding force of the cell surface, accelerating the shedding and renewal of epidermal cells, while stimulating the synthesis of dermal collagen and enhancing the moisturizing function, which is more effective for superficial atrophic scars caused by acne and acne marks after acne. Second, intense pulsed light, 1450nm laser, and pulsed dye laser can also help with the elimination of red acne marks in the later stages of post-inflammatory acne. Third, atrophic scars can also be treated with laser or ultra-pulsed carbon dioxide laser resurfacing. Larger atrophic scars can be treated with fractional laser or surgery. Fourth, since most acne patients have oily skin and lack of moisture, you can use medical skin care products that have the effects of oil control, regulation of water-oil balance and repair of the skin barrier, or masks containing collagen ingredients.
