Both red (around 630nm) and near infrared (around 830nm) LED light stimulate mitochondrial function on all cells, including fibroblasts, which are the collagen and elastin producing cells in the skin, tendons, ligaments and other tissues. So, yes, by improving mitochondrial and cell function in skin fibroblasts, red and near infrared LED light does boost both collagen and elastin…
Does infrared light really tighten skin?
Infrared light penetrates more than red light and can better reach the dermis where fibroblasts (collagen and elastin producing cells) and collagen structures are found. High-power LED phototherapy in the near infrared wavelength boosts mitochondrial function via the stimulation of cytochrome C oxidase enzyme. Improved mitochondrial function means better fibroblast function and increased collagen and elastin synthesis, meaning firmer skin. No other procedure is known to have this effect on mitochondrial function - only red light at around 630nm and infrared light at around 830nm. However, this effect is subtle and appears gradually and slowly, so infrared…
