What are the methods for repairing fall scars?

Everyone has some scars on their body to a greater or lesser extent. Many of these scars may be left behind when one accidentally falls. Many people are very concerned about the existence of these scars, especially when the scars are in obvious positions. They hope that there is some way to remove these scars. In fact, once scars appear, there is no effective way to completely remove them, and they can only be repaired.

Apply topical medication

Almost everyone with scars wishes there was a magic scar removal ointment that could make the scars disappear without a trace. Scar ointments can be classified into general pain-relieving moisturizing creams, anti-scar and anti-inflammatory creams containing steroids, moisturizing and softening creams containing silicone, and melanin-removing ointments used to lighten pigmentation. Since scars are normal connective fibrous tissues that heal wounds, they are inevitably formed and exist at any wound site. Topical ointments applied to the scar area are limited to minor therapeutic effects such as moisturizing and softening connective tissue, and lightening pigments, thereby improving and beautifying the appearance of the scar, but they cannot truly "remove the scar".

Skin resurfacing

Dermabrasion is mainly suitable for superficial depressed scars. The principle of dermabrasion surgery is to smooth the epidermis of the uneven scars, and then through the wound healing process, new epidermis will grow again, making the scars blurred and improving their appearance. However, grinding surgery can only be limited to a safe depth and is powerless for scars that are too deep. Therefore, it is only limited to improving relatively shallow scars and must be performed multiple times to be effective.

Laser therapy

Laser is suitable for superficial depressed and hypertrophic scars. When the laser acts on the skin, only the scar part of the skin surface is affected by the laser, and other tissues are not affected at all. These parts that are not affected by the laser will accumulate more collagen and elastin, which help the new generation and rearrangement of collagen in the dermis. In addition, laser irradiation will produce photothermal effect, photochemical effect, pressure effect, electromagnetic field effect and biostimulation effect on skin tissue, so that the damaged dead tissue in the skin scar can be quickly pyrolyzed, vaporized, or broken into tiny fragments, which will be engulfed by phagocytes in the body and excreted from the body, thereby achieving the purpose of smoothing the scar.

Radiological method

Radiation therapy is suitable for superficial hypertrophic scars. When the scar area is treated with radiation therapy, superficial X-rays and beta rays can significantly reduce the number of fibroblasts in the scar tissue, impair their function, reduce the synthesis of collagen fibers and matrix, and increase the decomposition of collagen fibers, thereby flattening and softening the scar area.

Surgery

For more severe superficial or hypertrophic scars, plastic surgeons may choose to use incision and suturing or skin grafting to improve and correct the scars. The cutting method is suitable for small concave and convex scars, such as chickenpox scars, ice pick-shaped acne holes, and scars that are too thick or concave. The surgical method is to excise the scar, then peel off the skin and subcutaneous tissue, reduce the tension on the wound and then carefully suture it to make it a more beautiful, thin, straight scar. However, unless it is absolutely necessary, it is best not to choose surgery to avoid the formation of new scars.
