Skin rubbing method: apply the cooling agent to the affected area to numb the skin and fix its surface, and then polish it with a rotatable stainless steel wheel inlaid with fine industrial diamonds. The edge of the scar can be polished, and the bottom can also be polished to enlarge the central part and flatten the surface of the repaired skin. Scraping can turn a deep box into a flat valley.
If the scar is serious, continue to pay interest tax for 6 months to 1 year. Suggestion: avoid the sun. After using the skin rubbing method, the skin turns black after sun exposure. Collagen is a kind of protein that can restore skin health. When injecting, doctors usually use highly refined bovine collagen and add lidocaine to it, which is a intoxicating agent that can poison the treatment site.
In order to confirm whether collagen injection can help to eliminate the scar left by acne, put your finger on one side of the scar and pull the skin. If the scar disappears, you are probably suitable for this treatment.
The treatment step is very simple: your doctor will produce it from the second layer of the skin-the dermis. Because the human body "dissolves" collagen, depending on the injection site, you may need another round of treatment within 3 to 9 months. Because a person has an allergic reaction to collagen. Similarly, collagen injection is not safe for pregnant or lactating women.
Fat injection: Deep scars caused by fat loss can be cured by fat injection. Sometimes it's called fat injection In this treatment, fat is obtained from another part of the body through surgery, washed and injected into the scar to increase the fat of the scar. This healing effect usually lasts for 6 to 12 months.
Chemical peeling method: mild or shallow peeling-only gently removing superficial skin cells-treated with trichloroacetic acid or α -hydroxy acid. For severe acne, doctors use phenol peeling, which usually requires general anesthesia by cosmetic surgeons. For common scars, doctors can peel them off with trichloroacetic acid. These peels are very effective in treating pit scars.
Punching and gouging: This treatment is very effective for patients with narrow and deep "ice pick" scars. The doctor cut the scar with a round integrated chisel and then stitched the edges together.
Laser skin rubbing: This treatment uses a carbon dioxide laser to polish the skin. Different from scraping, laser scraping is a relatively bloodless skin polishing method. However, like skin scraping, laser therapy also has its disadvantages-if it is not used properly, it will produce new scars or uneven spots.
