What are the benefits of LED and red light therapy?

As we age, our skin loses collagen and elastin, causing wrinkles and sagging. But LED light therapy can help address this by revving up the fibroblasts that produce collagen and elastin. This enhances skin texture and smooths out fine lines and wrinkles. Additionally, the light boosts blood flow, allowing skin cells to receive more oxygen and nutrients to speed up healing (Lemos et al., 2018).

Near-infrared light penetrates deeper into the skin than LED light due to its longer wavelength (Sadick & Makino, 2004). This allows it to reach and affect not just skin cells, but also underlying muscle and nerve tissues. Near-infrared light is particularly effective at reducing inflammation and easing pain, making it useful for treating injuries (Henderson, 2016). The heat generated when near-infrared light hits the skin helps ease pain and irritation (Sadick & Makino, 2004; Tong et al., 2018). Additionally, near-infrared light can ease muscle tension and speed up the healing of damaged tissues, especially after injuries (Benedek, 2022). Its deep tissue penetration also makes near-infrared light effective for treating conditions like cellulite, as it enhances circulation, reduces inflammation, and promotes fat breakdown. Combining the benefits of LED and near-infrared light therapies provides a comprehensive approach to skin rejuvenation and healing, addressing both surface and deeper tissue concerns.
