One can look at the aging process as the degradation of cellular processes. In the skin this results in reduced collagen production, leaving fine lines and wrinkles. In addressing skin aging, consumers take several approaches to attempt to rejuvenate the aging skin, often resorting to creams and skin applications. These creams can improve skin health, though might just temporarily mask the appearance of aging skin, instead of producing a longer-lasting rejuvenation of the skin.
This is where light therapy, either as a primary therapy or as a complement to other therapies to rejuvenate the skin, comes in. Low-level light therapy, also referred to as LLLT, in the infrared spectrum can penetrate the skin and increase energy levels. Adenosine triphosphate (ATP) provides energy to cells and increasing ATP can help speed the recovery and rejuvenation process in cells. Fibroblast cells produce elastin and collagen both of which are important proteins in connective tissue, and necessary for healthy-looking skin.
Applying low-level light therapy in the infrared spectrum (the 800 – 1200 nm range) helps to increase the energy process in these cells and to promote collagen and elastin growth.
Mitochondria produce ATP and this article by Nature magazine explains the role of mitochondria and ATP production in skin health, aging, and disease.
