Bumps and bruises in daily life inevitably leave scars. Many people try various methods to get rid of them, but the results are not satisfactory. Especially for girls, the first thing they do after taking photos is to fix the ugly scars. Today, we will briefly introduce how to repair common scars? First, depressed scars The surface of the scar is lower than other normal skin. Scars are mainly caused by acne, infection, trauma, surgery and other causes of skin dermal defects. In order to repair depressed scars, not only do we need to treat the scars on the skin, but we also need to choose the appropriate method to repair the defects according to the degree of depression in order to restore the normal shape. Depending on the size of the depression, different treatments are used. Depressed scars are usually categorized into larger depressed scars and smaller depressed scars. For larger depressed scars, we usually use a peel with lipofilling, or a peel with hypertonic fine suturing. Fractional lasers can also be used in combination with phototherapy. For smaller depressed scars such as acne pits and marks, we usually use peeling plus laser repair treatment or injectable medicine plus laser repair treatment. All of them can have a good treatment effect. Second, raised scars, also known as hyperplastic scars Mostly for burns, trauma, surgery or repeated infections in the dermis of the skin fibroblasts in the proliferative mutation. They usually have a reddish bulge, hard texture, and smooth surface, accompanied by pain and itching. Scars may also expand outward in a crabbed pattern. The histopathologic changes in raised scars vary at different stages of development, so treatment options differ at different stages. In the early stage, the focus is on inhibiting the proliferation of fibroblasts and blood vessels, which can be treated with a combination of lasers, usually fractional laser to remove scars and photon laser to remove pigmented scars. More than a year of old scars can be excised scars with ultra-decrease tension fine suture; or placed soft tissue expander to expand normal skin after repairing scars; can also be injected with drugs within the scar; or topical medication sprayed, coated and other methods, can improve the appearance. In the treatment of scars, we should also pay attention to the characteristics of scars that are prone to recurrence, so generally in the surgical excision of radiotherapy for joint treatment, will effectively inhibit the recurrence of good therapeutic effect. Scars are not scary, we need to diagnose which kind of scars, and then find a professional organization to develop a reasonable and effective program of professional doctors, the right medicine, in order to solve the problem without regrets.
