Experts from Dalian Plastic Surgery Hospital gave me a detailed introduction. Black-faced dolls use special light beams to irradiate specific media, producing light and thermal micro-explosion high heat energy, which is transmitted to the dermis of the skin. It can completely remove the aged cuticle, fully stimulate the renewal vitality of skin cells, and restore collagen fibers and elastic fibers. Black-faced dolls can stimulate the repair of collagen fibers, and use the natural repair function of the body to start the orderly deposition and arrangement of new collagen, thus instantly removing fine lines and wrinkles, whitening the skin, shrinking pores and restoring the original elasticity of the skin. The therapeutic principle of photon rejuvenation is to use intense pulsed light with a specific broad spectrum to penetrate the epidermis, and the energy is absorbed by the pigment group in the skin, so that the blood vessels are coagulated and the pigment group and pigment cells are broken and decomposed, thus achieving the effect of treating telangiectasia and pigmentation; Black doll laser is emitted by a laser beam with a single wavelength and low energy, which causes a micro-explosion reaction of carbon powder coated on the skin surface, stimulates tissue regeneration around pores and epidermis and dermis tissues, and achieves the effect of narrowing pores. The above is the introduction of the black-faced doll. I believe everyone is very clear. Nowadays, black-faced dolls are a very good way to beautify the skin. However, Xinhua plastic surgery experts at Dalian Plastic Surgery Hospital reminded that you must go to a regular professional medical institution and don't trust street advertisements!
