Brief Summary

Pulsed dye laser(PDL) and intense pulsed light(IPL) has been widely used in improving rosacea. To compare the efficacy and safety of PDL and IPL configured with different wavelength bands(Delicate Pulsed Light, M22 590, M22 vascular filter) in the treatment of rosacea, we designed a prospective, randomized controlled trial. We hope to make a comparison between PDL and IPL,between broad-spectrum IPL and narrow-spectrum IPL, between single-band IPL and dual-band IPL, and also provide clinical basis for clinicians and patients to develop individualized treatment plans.

Outcome Measures

Primary Outcomes (2)

  • Rosacea clinical score

    It includes objective symptom score(Flushing, Nontransient erythema, Telangiectasia) and subjective symptom score(Burning or stinging, Itching, Dry), with a 4-level score according to the standard grading system by NRS. Objective symptom is assessed by a dermatologist, and subjective symptom score is assessed by subjects themselves.

    from baseline(T0) to 4weeks after the final treatment(T3)

  • VISIA Red Area score

    using VISIA image system to record red area absolute score

    from baseline(T0) to 4weeks after the final treatment(T3)

Secondary Outcomes (1)

  • Pain score

    immediately after each laser treatment

Other Outcomes (1)

  • adverse effects

    through study completion, an average of 0.5 year
