Blue LED Phototherapy: Wavelengths, Anti inflammatory Effects, and Treatment Uses

The use of blue LED phototherapy is on the rise as it can be used as an anti inflammatory therapy. The benefits of the blue light LED phototherapy are that it is not invasive and has very few side effects. This treatment is used not only to treat skin diseases but also to speed up the process of healing by activating the production of collagen and slowing inflammation.
The blue light used in phototherapy produced by LED is very effective in conditions such as acne and psoriasis.
