Testicular tissue has a very high density of mitochondria. Red light therapy improves the electron transport chain efficiency in these cells, potentially reversing age-related decline in testosterone production and sperm quality.

This increased ATP production allows Leydig cells to operate at peak efficiency, synthesizing steroid hormones from cholesterol. It also reduces oxidative stress within the testes, which is a primary cause of age-related testosterone decline.

Red and Near-Infrared light penetrates the dermis and stimulates the mitochondria in skin cells. This boost in cellular energy (ATP) accelerates healing and increases the production of collagen and elastin.

It acts as a "time machine" for skin cells, reversing signs of photoaging and reducing inflammation (redness).
