How does the wavelength of LED light correlate with its penetration depth and therapeutic effects?
The wavelength of LED light determines both its penetration depth and therapeutic effects. Shorter wavelengths (like blue light) are absorbed by the outer skin layers and are effective for treating acne. Longer wavelengths (such as red and near-infrared light) penetrate deeper into the skin, where they can stimulate collagen production, reduce inflammation, and promote healing.
