The Efficacy of Intense Pulsed Light for Treating Erythematotelangiectatic Rosacea Is Related to Severity and Age

Background

Rosacea is a chronic cutaneous disease. Therapeutic modalities should be chosen based on the identified sub-types and clinical features in each patient. Vascular lasers, including intense pulsed light (IPL), are reportedly safe and effective in treating erythematotelangiectatic rosacea (ETR).

Objective

In this study, we assess the comparative efficacy of IPL related to several factors including clinical severity and the age of patients with ETR.

Methods

Patients with ETR were classified into two groups according to the National Rosacea Society Severity Guideline. Severity score and erythema index (EI) were measured using a clinical scorecard and mexameter. For additional evaluation of therapeutic efficacy, investigator and patient global assessments (IGA, PGA) were checked. Efficacy of IPL was analyzed according to severity score, EI, IGA, and PGA related to sex, age, lactic acid stinging test, and severity.

Results

Analyses of the efficacy of IPL according to severity score, EI, IGA, and PGA based on sex, age, lactic acid stinging test, and severity revealed significant differences with age and severity only.

Conclusion

This study supports the efficacy of IPL treatment for patients with ETR. IPL may be more effective in patients with more severe ETR and in younger patients with ETR.
