The Silk’n LED Face Mask 100 uses LED (Light Emitting Diode) light therapy which was originally developed to speed up the healing of wounds. It is now increasingly being used in skincare.
 
Research has shown that LED light stimulates cell division and the production of new cells, and supports tissue repair. For that reason, skin clinics all over the world use it to help improve the condition of the skin and to combat the signs of ageing.
 
The Silk’n LED Face Mask 100 has 4 colours of LED light, each of which works at a different wavelength and targets a specific concern. The mask contains 100 lights. Each colour and wavelength tackles a different skin problem to improve and restore the condition of the skin. The wavelength is referred to below in nm, which stands for nanometre. This indicates how deeply the light can penetrate the skin. Red light is designed to penetrate deeper into the skin than blue light, which works mainly on the surface. 
 
 Red light, 622nm: reduces fine lines and wrinkles, stimulates collagen and helps to improve blood circulation. Suitable for all skin types.

• Blue light, 463nm: targets the bacteria that cause acne and helps normalise oil production for clearer skin and improved skin texture. Suitable for oily skin.

• Yellow light, 592nm: reduces redness and soothes and softens the skin. Suitable for dry and sensitive skin.

• Purple light, 425nm: anti-inflammatory and anti-ageing properties to improve the vitality of the skin. Suitable for all skin types.
