Is laser safe for darker skin tones?

Our latest high-power laser hair removal machine. It’s safe for darker skin types because it offers two wavelengths: one being a 755 nm wavelength & a 1064 nm wavelength. The 1064 nm wavelength, also known as the Nd:YAG wavelength, is not as highly absorbed by melanin as other wavelengths. Because of this, the wavelength can safely treat ALL skin types because it deposits its energy deep into the dermis without relying on melanin to do so. And since Nd:YAG essentially bypasses the epidermis, this wavelength is a safe option for dark skin tones.

Basing on the selective light absorption theory, we let the diode laser generated by laser hair removal machine pass through the skin surface and penetrate the hair follicles by adjusting the wavelength, energy, and the pulse width to realize the hair removal purpose. In the hair follicle and hair shaft, there are plentiful melanin spreading between the follicle matrix and moving to the hair shaft structure. Once the melanin has absorbed the energy of laser, it will show a sharp rise in temperature and lead to destroy upon the surrounding follicle tissue. In this way, the unwanted hair will be removed completely.
