This custom 3528 SMD LED integrates dual wavelengths—620nm red light and 860nm infrared—into a single compact source. Designed specifically for aesthetic therapy, the red light rejuvenates skin and reduces inflammation, while the deeper-penetrating infrared relieves muscle and joint pain. Their synergistic effect enhances treatment outcomes for professional and home-use skincare and pain relief devices, delivering targeted, effective phototherapy.
