The interval of dot matrix laser generally takes about 1 to 3 months, and the course of treatment usually takes 3 to 4 times. Dot matrix laser is mainly suitable for rejuvenating, tightening, wrinkle removal, improving skin quality, such as coarse pores, treating acne, scars, rosacea, and pigmented diseases, such as bird spots, pigmentation, etc. If the treated skin is infected with bacteria or viruses, it is not suitable to use dot matrix laser, vitiligo is in the advanced stage, psoriasis and lupus erythematosus are not suitable for dot matrix laser, lactation, pregnancy, skin sensitive or light sensitive are not suitable for dot matrix laser.
At present, dot matrix laser is mainly used in the treatment of skin, such as pore shrinkage, acne pits, various scars and fine lines. The narrow sense of lattice laser is lattice carbon dioxide laser, and the broad sense of lattice laser. Dot matrix is an emission mode. Ordinary laser is a flashlight like large spot, which will cause great damage to skin tissue and easy to produce color sink scars. In order to avoid, a screen window can be added in front. Although it is still a large spot, it is composed of small beams arranged like a dot matrix. Therefore, the laser with mode generation is called dot matrix laser. The formation principle of dot matrix laser is more complex. Therefore, the purpose of using dot matrix laser is to reduce complications, reduce color sink and scar formation, and more effectively treat acne, scars and coarse pores under the condition of ensuring the stimulation depth.
