Red light therapy is a therapeutic technique that uses red, low-level wavelengths of light. When exposed to red light therapy, the body produces a biochemical effect that boosts the amount of energy stored in cells.
This helps cells to function more efficiently and repair damage, which is why it’s been used to treat scars and wounds. But red light therapy really took off in popularity for its efficacy in combating wrinkles, fine lines, sun spots, discoloration, and other signs of less-than-stellar skin health.
