Acne pimples, the depressed scar left after acne healing, can be removed by medication, phototherapy, hyaluronic acid filler and surgery. 1. Medication: You can follow the doctor’s instructions to apply Vitamin A drugs that promote epidermal cell renewal, such as Adapalene, Tazarotene and other gels, to promote recovery. 2. Photoelectric treatment: If the scar is more obvious after removing the mole, then the depressed scar can be improved by fractional laser, dye laser and other aesthetic treatments, the principle of which is mainly to irradiate the scar site by laser, and promote the improvement of the appearance of the scar by stimulating the dermal layer of the skin to proliferate collagen fibers, coagulation of the scar at the superficial capillaries, and other mechanisms. 3. Hyaluronic Acid Filling: Hyaluronic acid is usually injected into the skin, so that the body naturally absorbs and accepts it to help fill in the depressed areas and improve acne pits. 4. Surgery: If the depressed scar is more obvious and stable in shape, the scar tissue can be removed directly by local surgical excision, but considering the invasive way of surgery, it is recommended to go to the plastic surgery department for a fine surgery to avoid the formation of scar again after the surgery. There is no unique way to eliminate acne pits, and it is recommended that patients go to a regular hospital and cooperate with a specialist for standardized treatment.
