⚡ Quick Answer Red light therapy (photobiomodulation) uses specific wavelengths of light—primarily 660nm red and 850nm near-infrared—to stimulate cellular healing and regeneration:
Understanding LED light therapy colors is essential for choosing the right treatment. Red light (620-700nm) stimulates collagen, blue light (400-495nm) kills acne bacteria, near-infrared (700-1100nm) penetrates deep for healing, while yellow and green wavelengths address redness and hyperpigmentation.
