In recent years, the rise of laser beauty, with an appropriate amount of laser irradiation, can make the skin more delicate and smooth, because laser beauty is painless, safe and reliable, so it is favored by people. What skin problems can laser beauty solve.
What skin problems can laser beauty solve?
- Laser hair removal
Laser hair removal uses the principle of selective photothermal action. The melanin in the hair follicle can absorb a certain wavelength of laser, and the laser can accurately break the melanin, so as to achieve permanent hair removal. Hair growth is divided into three periods: growth period, degenerative period and resting period. Laser hair removal can directly act on the hair in the growth period. The length of the growth period of each part of the hair varies, so the interval of hair removal is usually 4 ~ 8 weeks. The thicker and darker the hair, the better the treatment effect, especially the removal of leg hair and armpit hair. Generally, the effect of laser hair removal is very significant after 5 ~ 10 times. It is a safe and effective hair removal method so far.
- Laser freckle removal
Laser speckle removal uses a high-intensity beam with a specific wavelength to selectively destroy the pigment in melanocytes, which can directly break the pigment and make the pigment particles discharged from the body with metabolism. But so far, laser can not achieve complete freckle removal, but can fade spots. The effect of laser freckle removal varies from person to person. Some people can see the effect 1 ~ 2 times, but some people need to do it 8 ~ 10 times to see the effect. After laser freckle treatment, it is necessary to set aside 30 days for metabolism, and then carry out the next step of treatment.
- Laser treatment of acne
Near infrared wavelength laser can inhibit sebaceous gland secretion and has a certain anti-inflammatory effect. The appropriate energy density and pulse width can be selected according to the severity of dermatitis. Generally, it needs to be done 4 ~ 8 times with an interval of 4 weeks. Pulsed fuel laser and intense pulsed light can make the red marks of inflammatory acne subside. At the same time, it can also improve the acne scars caused by dot matrix laser. Try to choose small spots, low energy and low array density.
- Laser removal of birthmark
The most common is the red birthmark, which is called hemangioma in medicine. Some are superficial and some are deep. Superficial birthmarks can be treated by laser, but deep birthmarks cannot be completely removed. Laser removal of birthmarks requires 3 ~ 6 courses of treatment, and an authoritative and professional plastic and cosmetic hospital must be selected.
- Laser wrinkle removal
The intense pulsed light of the laser can directly act on the skin tissue, produce photochemical and photothermal effects, rearrange the deep elastic fibers and collagen fibers, restore the original elasticity of the skin, and reduce or remove facial skin wrinkles. Laser skin tightening is treated once every three weeks. Generally, obvious results will be seen after 2 ~ 3 times of treatment.
Do not touch water within one week after laser treatment. The skin is sensitive to heat after scab formation. Wash your face with warm water at 38 ~ 40 ℃. When washing your face, pay attention to gentle action and do not rub your skin with force. In addition, after treatment, the skin may be extremely dehydrated, resulting in skin dryness or peeling. You can follow the doctor’s instructions to apply it with growth factor solution, or you can buy a medical facial mask. Do not do strenuous exercise during recovery. Excessive sweating may cause skin infection and prolong wound healing time. Cold spray or ice compress shall be given according to the severity of skin reaction. The scab can fall off by itself in about 10 days. It cannot be peeled off manually to avoid scar and pigmentation. Sunscreen work shall be done during recovery. When going out, use a sunshade or hat or apply sunscreen.
