Acne pits can be treated, and the most common method of treating acne pits is fractional laser, but if the pits are not particularly severe, they can be slowly restored after a period of skin metabolism. Acne pits are a condition of acne scars, and as an after-effect of acne, the most common cause is the collapse of the dermis after the loss of dermal collagen and the breakage of skin elastic fibers. The fractional laser can rearrange the collagen fibers under the acne pits, and after releasing the tension, the dermis will be refilled and the pits will be flattened. Laser treatment can be combined with local growth factor injection or cgf injection, both of which can get good filling effect and also improve the color of acne pits and also serve the function of local repair. If the acne pits are shallow, fruit acid and salicylic acid peeling treatment can be performed. When the face acne, diet is to pay special attention to eat more light and easy to digest food, do not eat spicy or easy to fire food, and pay attention to the facial cleanliness.
