Decrease Wrinkles, Increase Collagen 830 nm and 633 nm Comparison

Science study Red light therapy skin dose

76 patients received split face LED treatment with 830 nm, 633 nm, or a combination of 830 nm and 633 nm. The control group received a sham treatment. Patients received therapy twice a week for four weeks. Measuring skin elasticity and melanin revealed wrinkle reduction as high as 36% and up to 19% skin elacity increase. Researchers concluded that 830 and 633nm alone and in combination are effective wrinkle reducing wavelengths.

White (411-777) and Red (660 nm) Reduction of Wrinkles Over 12 Weeks

Science study Red light therapy skin dose

Researchers treated subjects with LED therapy the specific wavelength 660 nm (red for group 1) and a range of wavelengths from 411 to 777 nm (white for group 2). 52 women received 5.17 J daily for 12 weeks. Wrinkles significantly improved (reduced). Group 1 had slightly better results, but the differences were not significant.
