Optical Beauty Device

An optical beauty device uses LED light of specific wavelengths to irradiate the skin, achieving beauty effects such as anti-aging, spot lightening, anti-inflammation, and antibacterial action. 
Technical principle: Different wavelengths of LED light have different effects on the skin. 
Red light (630–660 nm): Stimulates collagen production, anti-aging, repairs, and improves fine lines. 
Blue light (415 nm): Kills acne bacteria, reduces inflammation, and prevents pimples. 
Yellow light: Improves dullness and brightens skin tone. 
It is gentle, painless, non-invasive, and suitable for long-term skincare.
