() Laser treatment of chloasma is based on the theory of selective photothermal effect of laser (ie, lasers of different wavelengths can selectively act on skin of different colors), and the high-intensity radiant energy generated instantaneously concentrates on the yellow color on the skin. On the plaque tissue particles, it is directly vaporized, crushed, and then excreted through the lymphatic tissue to achieve the effect of eliminating or reducing the chloasma. Because of the different causes of chloasma, on the basis of the treatment of the cause, the laser can treat the chloasma formed by the increase in pigmentation and deposition.
Chloasma is a pathological manifestation of dysfunction of pigment cells, and any traumatic treatment can aggravate pigment abnormalities. Q-510nm532nm755nm;Q1064nm For example, Q-switched short-wave laser can only obtain a transient pigmentation after 510nm, 532nm, 755nm and other amplitude laser treatments, but eventually the pigmentation will occur. Some Q-switched lasers, such as 1064nm lasers, use low energy. Density treatment, although has a significant effect on the treatment of chloasma, patients still have the possibility of recurrence after stopping treatment. ; At present, there is a view that the treatment of chloasma is still the treatment of drugs, appropriate measures to avoid light; laser due to the risk of recurrence and even pigmentation, and the cost of treatment is higher, the treatment should be carefully considered. In addition, the dot matrix laser has also been applied to the treatment of chloasma, and the efficacy has not been unanimously recognized. However, the new dot matrix laser provides patients with a new treatment and choice.
2000-150005 Laser treatment of chloasma is about 2000-15000 yuan, can be treated for one or more courses, each treatment needs to be treated 5 times. 8-16 After the treatment, the skin needs a process of natural absorption and metabolism. The doctor recommends that the interval between treatments be 8-16 weeks.
