Rosacea is a chronic inflammatory skin condition characterized by facial redness, visible blood vessels, and sometimes acne-like bumps. Because rosacea skin is already reactive, light therapy is a double-edged sword — it can reduce inflammation in some users but trigger flares in others. Approach with caution.

What the Research Says

Research on RLT for rosacea is limited but generally positive:

  • A 2018 study found that red + near-infrared light reduced rosacea severity scores by 35% after 4 weeks of treatment.
  • Dermatologists have noted that RLT can reduce the inflammation associated with papulopustular rosacea (the type with bumps).
  • However, RLT may worsen erythematotelangiectatic rosacea (the type with persistent redness and visible blood vessels) in some patients.

The key takeaway: RLT helps some rosacea sufferers, but not all. The only way to know is to test it carefully.

Pros and Cons for Rosacea

Potential Benefits

  • Reduces inflammation (the underlying cause of rosacea flares)
  • May reduce the frequency and severity of flares
  • Drug-free alternative to topical steroids
  • Improves skin barrier function over time

Potential Risks

  • Can trigger flares in some users (especially erythematotelangiectatic rosacea)
  • Heat from NIR may worsen redness
  • Skin sensitivity varies dramatically between individuals

Cautious Protocol for Rosacea

  1. Patch test first. Treat a small area of skin (1 inch) for 1 minute. Wait 24 hours to check for adverse reactions.
  2. Start with very short sessions. 2–3 minutes maximum for the first week. Increase gradually if no flares occur.
  3. Use red light only (no NIR). NIR may be too intense for rosacea skin. Stick to 633nm or 660nm red.
  4. Lower intensity is better. Sit 12–18 inches from the panel instead of 6 inches. Use a mask on a low setting.
  5. Stop immediately if you flare. If redness increases or skin feels hot/irritated, stop using RLT and consult your dermatologist.
  6. Consult your dermatologist first. Rosacea is a medical condition. Get your dermatologist's approval before trying RLT.

When to Avoid RLT

Don't use RLT for rosacea if:

  • Your rosacea flares are triggered by heat or light
  • You're experiencing an active flare
  • Your dermatologist has advised against light therapy

Frequently Asked Questions

Sometimes. RLT reduces inflammation in some rosacea sufferers, but it can trigger flares in others. The only way to know is to test carefully with a patch test and short sessions.
Yes, in some users. RLT can trigger flares, especially in erythematotelangiectatic rosacea. Always patch test first and stop if redness worsens.
633nm or 660nm (red light) is safest. Avoid NIR (830–850nm) which may be too intense and the heat can worsen redness.
Absolutely yes. Rosacea is a medical condition and your dermatologist can advise whether RLT is appropriate for your specific subtype.
Generally no. Wait until the flare has subsided before resuming RLT. Treating during a flare may worsen inflammation.
Track flare frequency and severity for 4–6 weeks of consistent use. If flares decrease in frequency or severity, RLT is helping. If flares increase, stop.
