the use of pnic technology can separate specific colors of light because they have different wavelengths and stimulate different layers of the skin by radiating their light through the epidermis. irradiation of different wavelengths has different effects on the skin: 1. blue light (about 465 nm): acne and rash. 2. red light (about 630 nm): improve blood circulation, reduce wrinkles and smooth skin. 3. green light (about 520 nm): relaxes the skin and reduces skin pain. 4. yellow light (about 592 nm): improve the skin's immunity. 5. purple light (about 490 nm): anti-bacterial and inflammation.
