Advantages of dot matrix laser wrinkle removal and rejuvenation: 1. Deep wrinkle removal: compared with traditional laser, dot matrix laser has stronger power. It can go directly to the deep dermis of human facial skin, stimulate the damaged part of dermis tissue for repair, and make the dermis produce more collagen and rearrange, which has the effect of rejuvenation. 2. High safety: the dot matrix laser adopts the dot matrix laser system. Using the biological excitation effect of the laser on the tissue, micro holes with a diameter of 120-1200 microns and a spacing of 500 microns can be made on the skin. These micro holes can be closed within one day after treatment without any trauma response. 3. Short recovery time: during treatment, a matrix shaped spot is formed at the part directly penetrated by the laser, and the skin immediately starts the transverse repair mechanism, and the epidermis will completely heal within 8 hours. In about 3-6 days, the scab of the skin falls off, the skin returns to its normal appearance, and the internal collagen regeneration can last for more than 6 months.
