There are small pits on the surface of the face, which may be left behind after the healing of acne, and can be repaired by topical medication, local injection of medication, phototherapy and other measures. 1. Topical medication: You can use topical medication such as cumeneoside ointment, hydroquinone cream, vitamin E ointment, etc., which can improve the circulation and have a certain auxiliary effect on the improvement of facial pits. 2. Local injection of drugs: if the depression is large, sodium vitrate can be injected into the depression, which can play the role of local filler; larger bumps can also be injected with glucocorticoids in order to soften and reduce the bump. 3. Photoelectric treatment: Fractional laser and erbium laser can be used to stimulate the growth of local collagen material, so as to improve the appearance of facial pits. It is recommended that those who are willing to be treated should go to a regular medical institution, and all medications and treatments should be used under the guidance of a professional doctor in order to avoid adverse consequences.
