Does Red Light Therapy Help Rosacea? What 23 Studies Show (2026)
Quick answer: red light therapy for rosacea
Red light therapy may help rosacea through anti-inflammatory effects that reduce inflammatory markers in the skin, improved circulation that supports healthy blood vessel function, and enhanced cellular energy that maintains skin barrier integrity. Studies report reduced baseline redness, fewer flushing episodes, and less sensitivity with consistent use. Improvements are gradual, not overnight. Rosacea skin is reactive, so start with short, low-intensity sessions and watch for heat-triggered flushing. Recommended wavelengths are 630-660nm (red) and 830-850nm (NIR), starting at 5 minutes and gradually increasing to 10-15 minutes, 3-4 times per week, over 8-12 weeks.
