Then we asked Shijiazhuang Jimei plastic surgery experts to introduce us: the black-faced doll was painted on the face through medical nano-carbon. After nano-carbon permeates into pores, the carbon powder particles are blasted by laser, thus crushing the dirt and cutin on the epidermis. The generated high-heat energy is transmitted to the dermis, which fully stimulates the renewal and vitality of skin cells, stimulates the regeneration and repair of collagen fibers and elastic fibers, and at the same time, uses the natural repair function of the body to start the orderly deposition and arrangement of new collagen, thus weakening wrinkles, shrinking pores, making the skin smooth and restoring its original elasticity. Carbon powder for the treatment of black-faced dolls is a common health care product, which has good absorption characteristics and is beneficial to human body. Secondly, 1064 nm laser is used, which belongs to the wavelength range commonly used in laser beauty. Long-term use in the field of laser beauty, harmless to human body. The harm of the real black-faced doll comes not from the black-faced doll itself, but from the guarantee of the beauty institution chosen by the beauty seeker, the operation of the skin beauty instrument of the black-faced doll by the treating doctor and the postoperative care of the black-faced doll. Therefore, it is very important to choose a formal professional plastic surgery institution. Experts from Jimei Plastic Surgery in Shijiazhuang remind you that regular plastic surgery institutions use imported equipment, and doctors have undergone strict training, so that beauty seekers can safely enjoy the process and effect of skin beautification through standardized treatment methods.
