Skin aging includes natural aging and photoaging. Skin photoaging is caused by chronically sun exposure damage, manifested as wrinkles, rough skin, dry, loose, irregular pigmentation, telangiectasia, and even for the development of benign or malignant tumor.

There are many methods to improve skin photoaging: drug therapy such as topical or oral vitamin A acid; cosmetics such as sunscreen, antioxidant, cutin stripping agent; surgical treatment including surgery, angioplasty, pouch blepharoplasty; injection therapy including intramuscular injection of botulinum toxin, hyaluronic filling lesions acid; peel treatment including traditional grinding, grinding, grinding and laser treatment of ceramics such as CO2 laser, Er:YAG laser, chemical peeling (three chloro acetic acid, phenol, acid); non ablative rejuvenation treatment including laser such as KTP laser frequency, pulsed dye laser, Q switch Nd: YAG laser (1064 nm) and the long pulse Nd: YAG laser (1320 nm), RF technology and intense pulsed light (Intense pulsed, light, IPL). Drug and cosmetic treatment has the disadvantages of slow effect, bad curative effect; surgical therapy, injection therapy and peel treatment have some skin trauma, slow recovery, postoperative complications; non ablative laser and RF technology is likely to cause inflammation after pigmentation, scar and other complications, and the single wavelength and small application scope. As a new generation of non stripping skin beauty, minimally invasive, safe, efficient, time-saving, wide indications and other advantages.
Light can be effectively reduced, wrinkle, freckle, capillary pores, increase skin elasticity. Light without damaging the normal tissue, by pigment groups such as melanin granules and hemoglobin selective absorption, pigment groups, expansion of vascular damage, decomposition, so as to achieve the treatment of pigmentation, capillary expansion effect. On the other hand, light effects on fibroblasts and the synthesis of new collagen, the collagen fibers and elastic fibers rearrange and make photoaging skin restore elasticity, wrinkles, shrink pores, skin rejuvenation.
