Which wavelengths are best for Anti-aging? Red and Near Infrared

Science studies support that a combination of red + near infrared is best for anti-aging. Red and near infrared light have distinct but complementary effects for anti-aging. Red is a shorter wavelength which targets the surface of the skin. Red LED stimulates the proliferation of dermal fibroblasts, which increases cell turnover and helps with brightening of skin. Near infrared is a longer wavelength that penetrates deeper into the skin and stimulates fibroblasts to secrete collagen, as well as has greater anti-inflammatory effect. Ideally you would use both wavelengths combined for best anti-aging effect.
