Do red light therapy panels actually work?

Across the reviewers and specialist communities we read, the consensus is cautiously positive for pain relief, recovery, and gradual skin improvements, but with two big caveats: results take weeks to months of consistent use, and they are usually subtle. Several r/redlighttherapy and r/SkincareAddiction posters report visible skin-texture and soreness benefits only after 2-3 months of near-daily sessions, while skeptics note effects can be hard to distinguish from placebo. Power output (irradiance) and consistent use matter more than brand marketing.
