Growth Factor Gel is not generally effective in treating scarring. Growth factor gel can promote the growth of DNA, RNA and proliferation of epithelial cells in the process of tissue repair above the skin of animals, which can shorten the healing time of wounds. Clinically, it is mainly used for the treatment of burn wounds, residual wounds, skin donor area wounds and chronic ulcer wounds, and it can’t treat keloid scars. Keloid scars are formed during the repair process of skin breakage. If the scar tissue does not proliferate excessively to affect the appearance or function, no special treatment is generally needed. If scarring is obvious and the patient has the will to treat, it is necessary to go to a regular medical institution under the guidance of specialists to take local injection of drugs or surgery and other measures to standardize the treatment.
