The Science Behind Red Light Therapy
We believe you deserve to see the science yourself. Below is a curated collection of peer-reviewed studies on red light therapy — organized by what you might be hoping to support: skin, pain, recovery, hair, sleep, and mood. Each link goes directly to PubMed or the publishing journal, so you can read the source for yourself.
This page is updated as new research is published. If you'd like us to add a study, or you have a question about how to interpret one, message our care team — we'd love to help.
