Huamei 1470nm Fractional Skin Tightening Wrinkle removal Beauty Machine

The 1470 nm diode laser is a monolithic semiconductor device that converts electrical energy directly into light. Compared to other laser sources used for skin rejuvenation, it offers significant advantages, including high conversion efficiency, a compact design, and cost-effectiveness.

Laser skin rejuvenation leverages the principle of selective photothermolysis, where tissue chromophores absorb specific wavelengths of light. In human tissues, water serves as the primary chromophore, comprising approximately 70% of the skin, making it ideal for effective rejuvenation treatments.

The 1470 nm laser delivers an ideal absorption coefficient for water, penetrating up to 400 μm into the dermis. Unlike shorter wavelengths, it is strongly absorbed by the eye’s cornea and lens, ensuring the energy does not reach the retina. Under maximum permissible exposure (MPE) limits, the 1470 nm wavelength is deemed highly safe, with its MPE value being a million times lower than the 1400 nm wavelength.
