What is Photobiomodulation Therapy and How Does it Help the Skin?

What is Photobiomodulation Therapy?

It is a kind of therapy that uses low-level energy in the form of light to penetrate the skin without causing visible skin injury. 

By delivering light energy into the skin, cellular changes are triggered that lead to wound healing, tissue regeneration, increased blood circulation, reduced inflammation, and decreased pain. 

How does this therapy work?

The light energy emitted is received by the mitochondria of our cells, which is responsible for producing energy. Once received, a series of reactions occur in the cell, creating more energy (ATP), reactive oxygen species, and nitric oxide, leading to wound healing. 

Know that there are different wavelengths manifested in different colors. 

Blue light: 400-470nm

Green light: 525nm

Yellow light: ~540nm

Red light: 630- 700nm

Near infrared (white) light: 700-1,200nm

The longer the wavelength, the deeper the penetration of the light energy. 

For example, the blue light is limited to the epidermis. This is why it is mainly used for superficial skin concerns like acne breakouts. In comparison, the yellow light can penetrate deeper into the dermis where vessels are found, which is why it can be used for problems like rosacea. For aesthetic concerns like wrinkles, scars, and stretch marks, red light therapy is the most effective because it can penetrate the whole length of the dermis and produce effects in collagen formation.
