Physically, light with a wavelength of 700 nm to 2500 nm belongs to infrared light. Generally, this kind of laser mainly removes birthmarks without leaving scars. In this case, you won't leave a scar, mainly to remove the birthmark.

The laser with 1064nm is a Nd:yag laser, which is a solid-state laser. Infrared fiber laser usually refers to erbium-doped fiber laser, which is 980nm/ 1480nm pump light.

Extended data

The principle of 1064 laser speckle removal is that different types of lasers produce different colors of light, and the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Therefore, the shaping mechanism uses a laser instrument to generate a high-intensity beam to make the pigment fade, so as to achieve the purpose of removing pigment spots.

Laser freckle removal is a kind of skin beauty project, which can not only remove all kinds of defects on the skin, but also make the skin smooth and tender, reorganize the original collagen tissue, thus shrinking pores, reducing wrinkles and restoring skin elasticity, health and luster. It can also eliminate hereditary freckles, and has better laser freckle removal effect on pregnancy spots, chloasma, freckles, sunburn, butterfly spots and other spots.

The treatment time of laser depigmentation is relatively short, only about ten minutes at most. After each treatment, the skin should be given a metabolic process. Therefore, the interval of laser pigmentation treatment is usually 3 months.
