Efficacy and Safety of Intense Pulsed Light with Dual-Wavelength Spectra (555-950 nm and 530-750 nm) for Erythematotelangiectatic Rosacea Treatment in Chinese Patients.

BACKGROUND

Erythematotelangiectatic rosacea is characterized by central facial erythema and telangiectasia, accompanied by sensations of burning and stinging. Erythematotelangiectatic rosacea can be addressed through various treatments. We aimed to observe and evaluate the clinical effectiveness of a short pulse narrow-spectrum Intense pulsed light (IPL) with wavelength of 530-750nm and 555-950nm for the treatment of erythematotelangiectatic rosacea.

METHODS

We retrospectively collected patient information on erythematotelangiectatic rosacea and evaluated the clinical outcome.

RESULTS

63 cases of erythematotelangiectatic rosacea were included. All patients received different sessions narrow spectrum IPL treatment with 555-950 nm and 530-750 nm filter combinations. The treatment efficacy rate was 57/63 (90.47%), all patients showed significant post-treatment Erythema Assessment Scale (EAS) levels reduction (p<0.05), and patients who received more treatment sessions tended to obtain greater EAS score reductions. A significant reduction (p<0.05) in the facial red areas was shown by VISIA images after treatment. 59 (93.7%) demonstrated improvement according to GAIS (Global Aesthetic Improvement Scale) scores. There were no significant skin adverse reactions were observed during treatment. All patients expressed satisfaction with the treatment.

CONCLUSION

The narrow-spectrum IPL with 555-950nm and 530-750nm wavelengths filter combinations for the treatment of erythematotelangiectatic rosacea has the advantages of a high erythema improvement rate and low adverse reaction.
