1.Photonic skin rejuvenation uses the principle of light selective absorption, with multiple spectral lines, acting together in the deeper layer of the skin, is absorbed by various pigment cells in the tissue and microvascular hemoglobin selection, without destroying normal tissue cells, so that various pigment cells are destroyed and decomposed, and also make microvascular coagulation, so as to get rid of pigmentation, age spots, freckles, dark circles and capillary dilation, etc. 2.Use of photothermal and photochemical effects, thermal stimulation of collagen and elastin, regeneration, reorganization and repair of collagen and elastin fibers, as well as the enhancement of vascular tissue function to improve circulation and accelerate the metabolic process of keratinocytes, so that the aging skin can be restored. 3. While tightening the skin and reducing pores, it can effectively regulate and inhibit sebaceous glands, remove “blackheads” and “whiteheads” and improve oily skin. 4. The photothermal and photochemical effects of the specific spectrum can kill the invasive Propionibacterium, achieving sterilization, acne removal, and acne mark removal. The selective action of E light can penetrate the skin directly to the root of the hair follicle in the deeper layer of the skin, selectively destroying the melanin and hair-growing cells in the hair follicle, so as to achieve the effect of getting rid of body hair.
