Acne marks are red or black traces left behind due to capillary dilation and melanin deposition after the skin has locally suffered from acne has healed. to get rid of acne marks, the treatment should be chosen according to the specific situation. 1. red acne marks: the skin has an inflammatory reaction at the acne site, which may cause skin lesions and cause local capillary dilation. When the acne heals and the skin lesions improve, the capillary dilation does not recover, leaving a red acne mark. You can use vitamin A acid drugs to promote vascular absorption and confine the local inflammation to improve the capillary dilation so as to achieve the effect of removing acne marks; 2. Black acne marks: the skin acne area has an inflammatory reaction and the inflammation will cause local melanocytes to release melanin. When the inflammation is limited or improved, melanin is deposited in this area, and a black mark is produced. Mucopolysaccharide polysulfate cream can be used, which promotes the synthesis of tissue mesenchymal cells and allows the regeneration of subcutaneous connective tissue to promote the absorption and fading of melanin. While using the medication, it is also necessary to change the bad behavior in daily life, such as not to eat some spicy, stimulating, greasy, too sweet food, pay attention to local hygiene, to work and rest regularly, and avoid staying up late. It is recommended to carry out active and correct treatment to avoid recurrence of acne. When the acne marks are more serious and the effect of using drugs to lighten them is not good, other methods such as laser can be taken to treat them.
