Photorejuvenation is effective, and the anti-aging effect of photorejuvenation for skin treatment is very classic and non-invasive, so it is also very well, as well as very widely used in clinical practice. Photorejuvenation can remove the pigment on the surface of the skin, dilate the superficial hair vessels, solve the fine wrinkles, including the enlarged pores, rough skin and dull skin color can be handled. The pulsed intense light treatment must be properly operated with better technology, better equipment, and medical workers who apply the equipment and technology well in order to achieve what the client needs and achieve the effect of skin rejuvenation. Photorejuvenation is suitable for the younger age group and the busy white-collar workers, and for those who do not have vacation time or miss work. Photorejuvenation is a non-invasive treatment. After the treatment, if it is dealing with the pigmentation on the surface of the skin, a thin scab will appear on the surface in 2-3 days, which is usually not visible to outsiders. Pulsed intense light can reach the superficial middle layer of the dermis and stimulate the growth of collagen fibers in the superficial middle layer of the skin because it has a wavelength of about 1200nm. The new collagen fibers can replace the aging collagen fibers, and the improvement of the superficial skin wrinkles is also very obvious.
