Research shows that the infrared laser has specific advantages in reducing fat accumulation, generating collagen and elastin and achieving the purposes of fat reduction and body shaping. Under the action of longer infrared wavelength, the light absorption of the material in melanin and hemoglobin is less, so that the material can be safely used for various skins, and the penetration of the material in soft tissues is deeper. The non-contact and non-invasive laser can reduce the number or volume of fat cells by heating the subcutaneous fat layer, thereby achieving the purpose of local fat reduction.

The medical accidents such as scald and the like are easily caused by overhigh temperature and untimely adjustment in the fat reducing process.
