Official Title: Non-ablative 1,550 nm Fractional Laser Therapy Versus Triple Topical Therapy for the Treatment of Melasma: a Randomized Controlled Split-face Study
Brief Summary: The purpose of this study is to determine whether the use of non-ablative fractional laser is safe and effective in the treatment of melasma.
Detailed Summary:
Sponsor: Netherlands Institute for Pigment Disorders
Current Primary Outcome: Physician's global assessment [ Time Frame: T0, 3 weeks, and 3 and 6 months follow-up ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- L-value [ Time Frame: T0, 3 weeks and 3 and 6 months follow-up ]Improvement of hyperpigmentation was assessed by color measurement through reflectance spectroscopy (Microflash 200 d, Datacolor International, Lawrenceville, GA). This instrument, with an aperture of 4 mm, determines color by measuring the intensity of reflected light of particular wavelengths. In this study, the obtained L value, indicating the lightness of the measured area of skin, was used.
- Melanin index [ Time Frame: T0, 3 weeks and 3, and 6 months follow-up ]Melanin index was measured using a spectrometer (Derma-Spectrometer, Cortex Technology ApS, Hadsund, Denmark) in order to assess changes in the amount of dermal and epidermal melanin.
- Patient's global assessment [ Time Frame: 3 weeks, 3 and 6 months follow-up ]Patients were asked to score the improvement of hyperpigmentation on a visual analogue scale (VAS) from 0 to 10 (Patient's Global Assessment, PGA) at all follow-up moments.
- Patient's satisfaction [ Time Frame: 3 weeks, 3 and 6 months follow-up ]Patient's satisfaction was scored on a visual analogue scale (VAS) from 0 to 10.
Original Secondary Outcome: Same as current
