Fractional laser is used to treat some skin diseases and wrinkles by using a new CO2 laser topical therapy. Experts introduce that fractional laser is very effective, and from the current fractional laser effect, its fractional laser effect is very good for both Caucasians and Yellow people. At present, this technology has been certified by China’s State Food and Drug Administration (SFDA), and the efficacy has been widely recognized by the medical aesthetic community. Fractional laser treatment scope: mainly used for local and comprehensive skin peeling, repairing photo-aging skin, improving uneven skin tone, enlarged pores, rough skin, skin laxity, etc. Especially suitable for removing various scar and wrinkles, acne scars, tattoos, pigmentation and pigmentation, as well as treatment of various pigmented moles, warts, acne, dermatomes, hemangiomas, etc. on any part of the body surface. Fractional laser treatment mechanism: In traditional laser treatment, the laser is formed in the lesion area with the same size of the laser spot pulse laser action point, while fractional laser is formed in the lesion area by a number of fine as a hair, arranged in a matrix of micro-pulse laser action points and intervals composed of fractional burning area, reducing the laser trauma area. These points have enough energy to penetrate the superficial layer of the skin and reach the dermis, stimulating collagen growth in the dermis and promoting collagen reorganization, which in turn promotes a series of skin reactions such as “regeneration” of the skin tissue. The interval between each laser action point ensures that only a small portion of the skin is exposed to the laser, and the skin not exposed to the laser can be used as a thermal buffer zone, which greatly reduces the thermal damage to the skin and facilitates rapid skin recovery, resulting in significant improvement in skin wrinkles, texture and skin tone in a short period of time and achieving the best clinical results. Fractional laser advantages: a variety of operating tools, a variety of spot shapes that can be set close to the skin based on the shape of the lesion, high surgical precision, short treatment time, minimal thermal damage, fast wound healing, and no severe pain. Patients generally need 3-4 treatments for skin improvement, with each treatment interval of 4-6 weeks. Fractional laser post-operative care: erythema and burning sensation may last for 2 days, scabbing starts 1-2 days after treatment and returns to normal in about 7 days. Ice packs can reduce erythema symptoms after surgery, epidermal growth factor can accelerate healing, and antibiotic cream can effectively avoid infection. To prevent infection, swimming, shower, sauna, etc. are not allowed until the scabs fall off after surgery, and sun exposure is avoided. After the scabs fall off, it is recommended to use a sunscreen with SPF 30 or above. Do not artificially pick at the scabs with your hands to remove them. Use some skin repair medication for 2-4 weeks during the recovery period. Discoloration may occur after surgery.
