Living cells are able to absorb light of different colours (wavelengths), and respond in different ways to each different light spectrum. The skin uses the light as a source of energy to fuel the repair and rejuvenation of damaged cells, or, in the case of treating acne, kill bacteria. The energy activates the production of collagen and elastin, boosts circulation and accelerates tissue repair.
Light exposure is often associated with negative aspects such as skin aging, but in fact, exposure to certain parts of the light spectrum can be highly beneficial.
We need light exposure for production of Vitamin D, and it can also influence energy and serotonin levels in the body. In the field of skin science, controlled exposure to blue, red and near-red light plays an important role in accelerating the skin’s natural repair processes. Skin cells that have been energised with light function more effectively and can regenerate faster which can lead to healthier, younger looking and more radiant skin.
