Yes, lots of studies show that red light therapy (RLT) works well for treating skin problems and managing pain. The following research findings and clinical evidence are available:
Evidence from doctors about how red light therapy can repair skin
Treat your skin to help it repair itself and look younger.
Stanford University Medical Center says that red light, when used at certain wavelengths, can help skin cells to renew and boost collagen production. This makes the skin look better and reduces fine lines and wrinkles.
Applications of photodynamic therapy (PDT)
In PDT, red light is used together with creams or liquids that are put directly onto the skin. These kill the skin cancer cells and help new skin to grow.
Making skin heal faster
A 2025 study found that LED red light therapy can speed up skin healing, mainly by controlling swelling and boosting antioxidant activity.
