5 types of cosmetic laser

YAG laser is still the standard method of re-aging skin rejuvenation treatment, non-gasification and intense pulsed light laser equipment to achieve moderate collagen remodeling, and shorter recovery period. A laser current challenge facing scientists is to improve non-gasification of laser treatment to produce a more lasting and effective results.


    1. The pulsed dye laser (PDL) over the years has been used for the treatment of vascular lesions, such as port wine stains and the like. Researchers through a series of carefully observed after treatment with PWS overlapping skin will be improved. Improve the skin has been demonstrated in the absence of vascular lesions of photoaging patients. Based on these findings, the FDA approved a PDL for rejuvenation. According to reports, the treatment of some histological markers, such as a significant increase in Ⅲ procollagen and skin thickness, suggesting that new collagen synthesis.
    2. Long pulse 1064nm Nd: YAG laser with melanin, hemoglobin and water as the role of the target, can penetrate the skin in sufficient depth, selective heating of the dermis to stimulate new collagen synthesis. 6-month prospective study shows that skin, skin color and wrinkles get mild improvement. In addition, according to some clinical observation, the laser for skin laxity may also play a certain degree of improvement.



    3.1540nmEr: YAG laser are three kinds of water as the target chromophore, and one can penetrate deep laser equipment 0.4-2mm. A prospective study showed that all equipment after 1 540nm laser treatment patients were followed up for visible wrinkles within six months of slow and sustained improvement. Transient erythema after postoperative adverse reactions limited to laser irradiation occurs immediately, and edema. Skin histology is not obvious until several months after the treatment was found in the dermis has collagen fibers.
    4.1320nmNd; YAG laser to another mid-infrared laser, with a refrigerant nozzle to protect the epidermis. One study showed 1320nm laser equipment and can induce the synthesis of new collagen wrinkle, not associated with the epidermis gasification. Adverse reactions were mild postoperative.
    5.1450nm semiconductor laser with the laser device of the two mid-infrared laser wavelength and penetration on similar, but the difference lies in its point lower peak energy, which leads to the need for longer exposure times. Such prolonged pulses are required before the pulse arrives, during and after cooling. A controlled prospective study showed that the use of 1450nm semiconductor laser device has a rear portion of the wrinkles mild clinical improvement. Based on these results the United States FDA2002. Above three infrared device (1320nm, 1450nm and 1540nm) can effectively improve the skin photoaging, and acne scar treatment is also effective, but can also be used in the treatment of skin laxity.
