What effect does red LED light have on the skin?

Red LED light therapy primarily works by increasing circulation and stimulating wound healing in the skin. This process enhances blood flow, which delivers more oxygen and nutrients to skin cells, promoting faster repair and rejuvenation. Additionally, red light has been shown to stimulate collagen production, an essential protein for maintaining skin elasticity and firmness. This effect is particularly beneficial for improving the overall appearance of the skin, reducing signs of aging, and aiding in recovery from various skin concerns.

While some red light therapies may have secondary benefits for conditions like hyperpigmentation and acne, the primary and most well-documented effects focus on circulation and wound healing. This understanding helps practitioners effectively use red LED light in a variety of skincare treatments.
