Blue light or red light?

 

There are various kinds of LED facials available on the market today, and the technology is rapidly evolving. Some skin treatments involve the use of blue light, while some only use red light.

The basic premise of LED skin therapy is that different colours trigger different reactions beneath the epidermis and penetrate the skin at varying depths. Blue light is generally used to kill the bacteria that causes acne, providing an effective treatment for blackheads and whiteheads, whereas wavelengths of red light are normally used to speed up healing and stimulate collagen production, simultaneously shrinking enlarged pores and tightening the skin.

LED treatments are painless, non-invasive and no downtime is required.
