Dermabrasion: A coolant is applied to the affected area to numb the skin and fix its surface, which is then polished with a rotatable stainless steel wheel set with tiny industrial diamonds. The protruding edges of the scar can be polished, and the bottom can likewise be subjected to polishing, so that the central part increases and the surface of the rectified skin becomes flat. The abrasive skin method can turn a very deep box into a flat valley. If the scar is very severe, it lasts for 6 months to 1 year above the heavy profit tax. Advice: avoid seeing sunlight. After using the skin rubbing method, sun exposure produces problems such as skin darkening. Collagen is a protein that restores the skin to health. For injections, internists usually use highly refined bovine collagen to which lidocaine, an intoxicating agent that can travel openly to the treated area, is added. To confirm if collagen injections can help eliminate acne scars, place a finger on one side of the scar and pull on the skin. If the scar disappears, probably you are suitable for the treatment with this method. The treatment steps are very simple: your doctor will produce the skin from the second layer of the skin – the dermis. Since the human body “dissolves” the collagen, you may undergo another round of treatment in 3 to 9 months, depending on the site of the injection. This is because one person has been tested for allergic reactions to collagen. Likewise, collagen injections are not yet safe for women who are pregnant or breastfeeding. Lipoinjection: Very deep scars caused by fat loss can be healed by fat injection. This is sometimes called lipoinjection. In this treatment, fat is surgically obtained from another part of the body, rinsed and injected into the scar, causing the fat in the scar to grow. The effects of this healing usually last from 6 to 12 months. Chemical peels: Mild or superficial peels – only the uppermost layer of skin cells is gently removed – are treated with trichloroacetic acid or a-hydroxy acid. For very severe acne, doctors use phenol peels, which are usually performed by a cosmetic surgeon under general anesthesia. For normal scars, you can have your doctor perform a trichloroacetic acid peel. These peels are very effective in healing pitted scars. Perforated chisel excision: This treatment is very effective for scars that have a narrow, deep “crushed ice pick” shape. The surgeon removes the scar using a circular, overmolded, cutter-like chisel and then sews the edges together. Laser skin abrasion: This treatment uses a CO2 laser to polish the skin. Unlike the abrasion method, laser resurfacing is a relatively non-bleeding method of skin resurfacing. But like the abrasion method, laser treatment has its drawbacks – it can create new scars, or uneven discoloration, if used incorrectly.
