Acne and pimples, one after the other, leave behind acne marks and scars, turning the originally white skin into the surface of the moon. This is a big problem that has been plaguing the majority of beauty lovers for a long time. The actual fact is that you can use some topical medication with anti-inflammatory and anti-bacterial effects, such as benzoyl peroxide ointment, fusidic acid cream, clindamycin gel, etc. 2, gray and black acne marks red acne marks over time, after the inflammation subsided, often gradually formed some gray or gray and black acne marks. This is when we should do what? 1, topical medicine: you can rub hydroquinone cream. 2.Fruit acid treatment: Fruit acid treatment has a good effect on treating acne, gray and black acne marks and improving skin tone. You can usually use some skin care products containing antioxidants (such as vitamin C, arbutin, resveratrol, etc.). It is important to pay attention to sun protection, as UV rays will further stimulate melanocytes leading to pigmentation and the formation of acne marks. Second, acne scars Scars are often formed during the healing and repair process due to deeper skin damage. For minor general superficial scars, they will often become less visible over time, so no special treatment is needed, just be patient. For more obvious scars, taking medicine or rubbing medicine is often not very useful and more often requires the help of some cosmetic techniques such as laser and local injection, or even surgical treatment. 1, acne pits (atrophic scars) can choose carbon dioxide fractional laser, erbium laser, erbium glass laser, radio frequency fractional, etc.; other methods include micro-needling, injection filling, etc. 2.Proliferative scars Mild ones can be treated with topical compound heparin sodium allantoin gel, silicone gel ointment or scar paste, more serious ones can be treated with local injection of hormone, and 595nm laser treatment, etc. For severe scars, it is best to go to a major plastic surgery hospital for a surgical solution. The treatment of scars is often comprehensive, and a patient may have several types of scars at the same time, so the treatment cannot be completely solved by a single means. As the old saying goes, “The upper doctor treats the untreated disease, the middle doctor treats the desired disease, and the lower doctor treats the existing disease”, so is the treatment of acne marks and scars.
