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…
