Red Light Therapy in Winter: Do You Need Longer Session Times?
Short Answer:
If the stratum corneum (the outermost layer of your skin) becomes thicker during winter, you may consider slightly increasing the duration of Red Light Therapy (RLT) treatments. However, the difference is usually minimal, and RLT can still be effective year‑round.
Why Winter Skin is Different
During winter, cold temperatures and low humidity cause the skin to lose moisture. In response, the stratum corneum often becomes thicker as a protective measure. This increased barrier can slightly reduce the efficiency of treatments relying on light penetration, such as Red Light Therapy.
Will Red Light Therapy Still Be Effective?
Absolutely! Red and Near‑Infrared Light Therapy operate with wavelengths (around 660–850 nm) that penetrate the skin and underlying tissue. Even with a thicker stratum corneum, Red Light Therapy can still:
✅ Stimulate cellular activity
✅ Enhance collagen production
✅ Promote healing and reduce inflammation
The thicker outer layer may slightly affect surface absorption, making longer exposure or slightly increased session times beneficial in certain cases.
Should You Increase Session Duration in Winter?
In general, Red Light Therapy settings remain effective across seasons. However:
-
If your skin feels drier or thicker due to cold weather, an additional 1–3 minutes per session may be advantageous.
-
Always listen to your skin and adjust gradually.
-
Consult a dermatologist or skincare professional for personalized recommendations.
Final Thoughts
While a thicker stratum corneum in winter may slightly reduce Red Light Therapy efficiency, the difference is usually minor. Minor adjustments to exposure times can help ensure consistent benefits across seasons.
Remember:
✅ Red Light Therapy works effectively year‑round.
✅ Longer exposure may be helpful if the skin’s surface is significantly thickened.
✅ Always seek personalized advice if you’re unsure about making adjustments.
