With the photochemical effect of the LEDs, we intercept a single red light the narrow band is 660nm± 10nm, a single yellow light the narrow band is 590 ± 10nm and a single blue light the narrow band is 415 ± 10nm. Under the three different lights have specific effects on therapies and functions, we research and development the beauty products saint the LEDs Spa beauty instrument. This beauty instrument uses for the cold light irradiation, and it will not have the uncomfortable feeling of skin dehydration and high temperature. It is a big step in the field of beauty care instruments.
660nm wavelength red light has the effects of anti-tissue inflammation and activation of the injured skin cells. "Red light (660 nm)may have anti-inflammatory properties by influencing cytokinase release from macrophages", quoted from medical literature: Lasers Surg. Med., 9, 497 (1989)
It is suitable for any skin, and can stimulate fibroblast proliferation of collagen to make skin soft, smooth and more flexible so that to achieve the effect of anti-aging. "To slow down collagen breakdown, repair damaged tissue to replace old tissue, and build up new collagen to holds cells together with a high degree of elasticity and improve skin conditions in a smooth and fresh appearance for achieving anti-aging effect.

Blue Light Therapy
The high-technology LEDs blue light acne phototherapy initiated through the save and efficient LEDs Blu-ray photosensitive material in skin cells or endogenous pigment bacteria, form of singlet oxidation and excessive free radical induced abnormal keratinizing epidermal cell death. Its specific wavelength can be targeted to destroy acne bacteria, regulate sebum production, leaving no scars, no side effects. 415nm wavelength blue light has been confirmed has the effect of photodynamic therapy on acne caused by Propionibacterium acnes elimination. "Irradiation of P. Acnes with blue visible light predictably leads to bacterial destruction given the absorption peak of porphyrins produced by the bacteria at 415 nm"quoted form medical literature: Br J Dermatol., 142, 973 (2000)
In addition to acne and oil control, to reduce P-Acne productions, and refresh skin conditions. The LEDs blue light can directly kill the Propionibacterium acnes, scientific eliminate the types of acne, suppression of sebum production and reduce hair follicle obstruction, triple therapy mechanism to ensure completely get rid of stubborn acne. Compared with traditional methods, it has the following advantages:
Ø Quick and short course: Instant result, so that patients can complete the full treatment easier, the overall treatment time will short 1/3 of the traditional treatment methods.
Ø No pain: No stimulation of the skin, no photosensitive phenomenon, the treatment process is easy, without any pain.

Yellow Beauty Spectrum
The 590nm wavelength yellow light can blemish whitening; Increase the absorption of skin care products. From some medical literature, Dermatol Surg., 31, 1199 (2005), the yellow light is suitable for all skins, improve cellular oxygen exchange, improve the skin tone and dramatically promote the absorption of vitamin skin care products.
Both the yellow light and red light can promote the role of skin blood circulation, simulate dermal fibroblast proliferation of collagen, and can improve the metabolism of aging cells to achieve the skin rejuvenation
