laser cosmetology solve?
1. Laser hair removal
Laser hair removal uses the principle of selective photothermal action. Melanin in hair follicles can absorb a certain wavelength of laser, and laser can accurately break melanin, so as to achieve permanent hair removal effect. Hair growth is divided into three periods: anagen, catagen and telogen. Laser hair removal can directly act on the hair in the anagen period. The length of the anagen period varies for each part of the hair, so the interval between hair removal is usually 4 to 8 weeks. The thicker and darker the hair is, the better the treatment effect is, especially for leg hair and armpit hair. Generally, the effect of laser hair removal is remarkable after 5 to 10 times, which is a safe and effective method of hair removal so far.
2. Laser freckle removal
Laser freckle removal uses a high-intensity beam of light with a specific wavelength to selectively destroy the pigment in melanocytes, which can directly break the pigment and make the pigment particles follow the metabolism out of the body. But so far, laser can not achieve complete freckle removal, but can only fade spots. The effect of laser freckle removal varies from person to person, some people can see the effect 1 to 2 times, but some people need to do 8 to 10 times to see the effect. After laser freckle removal treatment, it is necessary to set aside 30 days of metabolic time before the next step of treatment.
3. Laser treatment of acne
near-infrared wavelength laser can inhibit sebaceous gland secretion and has a certain anti-inflammatory effect. It can choose the appropriate energy density and pulse width according to the severity of dermatitis, usually 4 to 8 times, with an interval of 4 weeks. Pulsed fuel laser and intense pulsed light can fade the red marks of inflammatory acne, and also improve the acne scars caused by lattice laser. Try to choose small spot, low energy and low lattice density.
4. The most common laser birthmark
is red birthmark, which is called hemangioma in medicine. Some are superficial and some are deeper. Superficial birthmarks can be treated by laser, but deep birthmarks cannot be completely removed. Laser birthmark removal requires 3 to 6 times of treatment, and an authoritative and professional plastic and cosmetic hospital must be chosen.
5. Laser Wrinkle Removal
The intense pulsed light of the laser can directly act on the skin tissue to produce photochemical and photothermal effects, which can rearrange the deep elastic fibers and collagen fibers, restore the original elasticity of the skin, and reduce or remove facial wrinkles. Laser skin tightening is treated about once every three weeks, and the obvious effect will be seen after 2 to 3 times of treatment.
Warm tips
: Do not touch water within a week after laser treatment. The skin is sensitive to heat after scabbing. Wash your face with warm water at 38 ~ 40 ℃. When washing your face, pay attention to gentle movements and do not rub your skin hard. In addition, after treatment, the skin may be extremely dehydrated, resulting in dry skin or peeling, can follow the doctor’s instructions to use growth factor liquid to smear, can also buy medical mask. Do not do strenuous exercise during recovery. Excessive sweating may cause skin infection and prolong wound healing. Give cold spray or ice compress according to the severity of skin reaction. The scab can fall off by itself in about 10 days, and can not be peeled off artificially by hand, so as to avoid scar and pigmentation. During the recovery period, it is necessary to do a good job of sunscreen, and use sunshade or sunshade hat or apply sunscreen when going out.
