Summary
Low-energy delicate pulsed light (DPL) effectively treats sensitive skin (SS) by reducing redness and improving skin sensitivity. This study found DPL to be a safe and beneficial therapeutic option for patients experiencing SS.
Area of Science:
- Dermatology
- Photomedicine
Background:
- Sensitive skin (SS) affects approximately 50% of the global population with no standardized treatment.
- Photovoltaic technology is emerging for SS treatment, but the efficacy of low-energy delicate pulsed light (DPL) remains under investigation.
Purpose of the Study:
- To evaluate the efficacy and safety of low-energy DPL as a treatment for sensitive skin.
Main Methods:
- 181 patients with SS received low-energy DPL (5.0-6.8 J/cm²), with treatment intervals adjusted for severity.
- Skin sensitivity was measured using the SS-10 scale, and facial erythema was assessed via the Clinician Erythema Assessment Scale (CEA) and VISIA-CR imaging.
- Adverse reactions were monitored throughout the treatment period.
Main Results:
- Significant improvements in SS-10 scores (p < 0.001) and CEA scores (p < 0.001) were observed.
- VISIA-CR analysis confirmed a significant reduction in facial erythema (p < 0.001) compared to baseline.
- No significant adverse effects were reported by any patients during the study.
Conclusions:
- Low-energy DPL demonstrates significant efficacy in improving sensitive skin symptoms and reducing facial redness.
- The treatment is well-tolerated and presents a safe therapeutic option for managing sensitive skin conditions.
