Compared with general speckle removal methods, laser speckle removal is better and faster. Laser freckle removal is to use the laser emitted by the therapeutic instrument to successfully penetrate the diseased skin and enter the diseased area to treat the pigment in the diseased area. Pigment will change under the irradiation of strong laser, and then it will be excreted with the metabolic function of human body to achieve the purpose of freckle removal.
The freckle removal methods selected for different spots also directly affect the freckle removal effect, such as congenital spots and acquired spots, deep spots and shallow spots, which are usually treated according to spots.
After continuous improvement, laser speckle removal has become a mature speckle removal technology, but the number of times laser speckle removal needs treatment varies from person to person, generally around 3-5 times. Depending on the patient's situation, the number of treatments may be more or less than 5 times. The time interval of each treatment is generally about 2 months. Generally, after the third treatment, the symptoms will be significantly improved.
Laser freckle removal is usually done once a month, and the growth cycle of the skin is 28 days. After each laser freckle removal, the skin needs a process of absorption and regeneration.
Generally speaking, the success rate of laser freckle removal is relatively high, but pigment spots can be removed or removed repeatedly. Because laser can only remove the existing pigment, it can't prevent the stain from appearing again. Therefore, the laser treatment effect of congenital pigment is not bad, but the acquired spots and chloasma may grow back after treatment, so the sunscreen maintenance after treatment is more important.
