Acne pits and hollows can be repaired by applying vitamin E to the area of the pits, and vitamin E has a very good moisturizing and anti-aging effect, and long-term use will not cause harm to the skin. The most common cause of acne pits is the breakage of skin elastic fibers and the loss of collagen in the dermis, causing the collapse of the dermis, which can be repaired. If the acne pit does not exceed six months, it can be recovered slowly through human skin metabolism; if it does not recover well in more than six months, it needs to be treated, mainly by fractional laser, together with topical growth factor gel. The treatment can also be combined with compound colored light or red and blue light exposure to promote recovery and shorten the treatment time. During the treatment period, patients should keep their face clean and hygienic, do not use skin care products casually, but carry out daily skin care under the guidance of the doctor, and ensure sufficient sleep time.
