1.Introduction of instrument: LED phototherapy skin mask instrument is the use of photodynamic theory, activate the deep cells, make the skin better metabolism. After the light is absorbed by the skin, the light can be converted into energy within cells, relaxation and strengthen capillaries and photochemical reaction with the skin - an enzymatic reaction, the cells increase as "guardian" and "cleaner " catalase (Catalase) and superoxide dismutase (SOD) activity. Increased ATP generation source of cellular energy (ATP) decomposition. Promote cell metabolism and synthesis, increase glycogen and protein content, which stimulated collagen born five times. Stimulate the secretion of growth factors in vivo alkaline synthetic fibers (BFGF) epidermal growth factor (EGF), and the collagen fibers and elastic fibers rearranged, and the elimination of blocking the formation of melanin, accelerate cell growth, accelerate blood circulation, stimulate fiber cell tissue produce collagen, increase skin elasticity, to repair aging skin, acne skin, fade spots, improve firmness, ease of care and sun burns, and so plays an important role. 2.Instrument function: LED phototherapy skin mask instrument that uses the principle of light irradiation, both simple and safe, but also to re-use to achieve the purpose of facial skin care. It solves the whitening, skin aging problem fundamentally, namely: Let increased activity of cells; promote cell metabolism, make the skin secretion of collagen and fibrous tissue to fill itself. Accelerate blood reflux, increase skin elasticity and improve skin complexion, dull conditions, so as to achieve whitening, skin rejuvenation, wrinkle, repair, etc. Blemish effect. Instruments were based on the original technology upgrade, using seven different colors cold light, namely red, blue, green, yellow, purple, blue, laser light, each light has a different effect, you can handle different skin problems, the effectiveness of a variety of instruments, practical and affordable.
