The skin barrier briefly explained
The skin barrier helps retain moisture and forms an important first protective layer against external influences. A compromised barrier can be associated with dryness, tightness, or a sensitive reaction.
Where does red light therapy come in?
Photobiomodulation is being investigated for its potential effects on cellular processes and recovery. This makes red light therapy interesting within a broader skincare routine, but the evidence for a specific consumer routine is not automatically the same as evidence from research.
What red light therapy does not replace
An LED device does not replace a foundation of gentle cleansing, appropriate hydration, and UV protection. For irritated skin, less is often more: keep the routine simple and follow the instructions of the specific device.
Conclusion
Red light therapy can be interesting as part of a well-considered routine. However, the skin barrier itself remains the foundation: build up slowly, do not overtreat, and keep expectations realistic.
