Brief Summary

Acne is one of the most common conditions that patients seek for help in dermatological clinic. Nowadays, conventional treatment including topical agents(retinoids, antibiotics ,antiseptics and keratolytic agents) and systemic agents( antibiotics and retinoids) give a satisfying result but not to every patient. Some patients are not well respond to conventional therapy while some patients are unable to tolerate side effects of the treatments. Therefore, interventions to reduce acne are vigorously experimented . Lights and lasers including intense pulsed light, pulsed dye laser with or without photosensitizer and infrared lasers have been found to be useful in treating active inflammatory acne. Although,pain ,downtime and poor response of comedonal acne are limitations of those lights and lasers therapy. 2940 nm Erbium:YAG laser which has both resurfacing and photothermal effects is our laser of interest to seek for its efficacy in the treatment of inflammatory acne.

Outcome Measures

Primary Outcomes (1)

  • percentage change from baseline of inflammatory acne lesion count at 6 week after 1st 2940nm Er:YAG laser treatment

    % change from baseline = (NV- NB)/NB x 100% NV = number of lesion at each visit NB = number of lesion at baseline

    6 week

Secondary Outcomes (3)

  • Safety

    week0,2,4

  • Photographic clinical improvement

    week 2,4,6 and 10

  • Patient satisfaction

    week 6
