Scar is a natural product in the process of human trauma repair. Scars can be roughly divided into two types: hypertrophic scars and concave scars. Scars not only affect the appearance, but also make people feel insecure. At present, there are many ways to remove scars, but in fact, once scars are formed, no one can completely remove them, but they can be repaired to the greatest extent. Bian Xiao will help you understand the common scar repair methods in clinic:
External use of drugs
Almost everyone with scars is looking forward to a magical ointment that can remove scars and make them disappear without a trace. Scar ointment can be divided into ordinary moisturizing ointment, anti-inflammatory ointment containing steroids, moisturizing and softening ointment containing silica gel, and melanin-removing ointment used to dilute pigmentation. Scar is the normal connective tissue of wound healing, so it will inevitably form and exist in any wound. External ointment applied to scar can only slightly moisten and soften connective tissue and dilute pigment, thus improving and beautifying the appearance of scar, but it can't really "remove scar".
Skin grinding operation
Dermable skin is mainly suitable for superficial concave scars. The principle of dermabrasion surgery is to smooth the epidermis of concave-convex scar, and then grow a new epidermis through the process of wound healing, which makes the scar blurred and improves the appearance. However, the grinding operation can only be limited to a safe depth, and there is nothing that can be done for scars that are too deep. Therefore, it is only limited to improving superficial scars, and it will take several more times to be effective.
Laser therapy
Laser is suitable for superficial depression and hypertrophic scar. When the laser acts on the skin, only the scar on the skin surface is affected by the laser, and other tissues are not affected. These parts that are not affected by laser will accumulate more collagen and elastin, which is helpful to the regeneration and rearrangement of collagen in dermis. In addition, after laser irradiation, it will produce photothermal effect, photochemical effect, pressure effect, electromagnetic field effect and biological stimulation effect on skin tissue, so that the damaged and necrotic tissue at the skin scar can be quickly pyrolyzed, gasified or broken into tiny fragments, which will be excreted after being swallowed by phagocytes in the body, thus achieving the purpose of calming the scar.
Radiological method
Radiotherapy is suitable for superficial hypertrophic scars. When radiotherapy is used to treat scars, both superficial X-rays and β-rays can greatly reduce the number of fibroblasts in scar tissue, damage their functions, reduce the synthesis of collagen fibers and matrix, and increase the decomposition of collagen fibers, thus making scars flat and soft.
surgical operation
For severe superficial or hyperplastic scars, plastic surgeons will choose cutting, suturing or skin grafting to improve and correct the scars. Cutting method is suitable for small concave-convex scars, such as chicken pox scars, ice cone pockmarks, too thick or sunken scars. The surgical method is to remove the scar first, then peel off the skin from the subcutaneous tissue to reduce the tension of the wound, and then sew it carefully to make it a beautiful and young linear scar, but it is best not to use the surgical method as a last resort to avoid forming new scars.
