For loss of laxity in the skin, which LED light and wavelength are recommended?

The recommended LED light and wavelength for addressing loss of laxity in the skin is red light at 640 nm. Red light therapy is known for its ability to penetrate deeper into the skin layers, stimulating collagen production and enhancing cellular regeneration. This increased collagen helps improve skin elasticity and firmness, effectively combating laxity. The wavelength of 640 nm is particularly effective in promoting healing and rejuvenation processes due to its ability to stimulate fibroblasts, which are vital for collagen synthesis.

Other colors and their wavelengths serve different purposes; for example, blue light at 470 nm is primarily used for acne treatment as it targets the bacteria that cause breakouts. Yellow light at 590 nm is often associated with skin rejuvenation and reducing redness but may not be as effective as red light for improving laxity. Green light at 525 nm is used for pigmentation issues and skin tone improvement rather than directly addressing laxity. Thus, red light therapy at 640 nm is the optimal choice for enhancing skin firmness and combating loss of laxity.
