Laser can produce a kind of visible light with high-intensity instantaneous energy. Different wavelengths act on our skin and are absorbed by different pigments. Laser has been developed for decades, and has also been applied to our beauty and medical industry. Up to now, there are different laser instruments, including common beauty lasers.
