A Pilot Study Testing 1064nm Q-switch Laser Versus Glycolic Acid Peels for the Treatment of Melasma

Not Applicable

Completed

• Conditions: Melanosis
• Interventions: Device: 1064nm Q-switch Laser; Other: Glycolic Acid Peels

• Registration Number: NCT01976273
• Lead Sponsor: Northwestern University

Brief Summary

The purpose of this study is to find out the safety and effectiveness of 1064 Q-Switch Laser Therapy compared to Glycolic Acid Chemical Peels for the treatment of melasma.

Detailed Description

Participants in this study will be patients at the dermatology clinic who are clinically diagnosed with at least a 2X2 cm patch of melasma on each side of their face (forehead or cheek). Starting at 2 weeks before treatment (week 2), both sides will be pretreated and primed with 4% hydroquinone with, if necessary, 2.5% hydrocortisone cream BID. On the treatment day (2-weeks) and 6-weeks one half of the subject's face will receive glycolic acid peels and the other half of the face will receive 1064nm Q-switch laser. This study is a pilot study designed to determine feasibility of these procedures.

Arm && Interventions

Group	Intervention	Description
1064nm Q-switch Laser	1064nm Q-switch Laser	The 1064 Q-Switch Laser is a medical device that uses a focused laser to remove dark pigment (color) from the skin.
Glycolic Acid Peels	Glycolic Acid Peels	A Glycolic Acid Chemical Peel is a mild skin treatment used to correct uneven texture and color by removing dead cells from the skin's outermost layer.

Primary Outcome Measures

Name	Time	Method
Visual Analog Scale (VAS) of Improvement Rated by a Blinded Dermatologist From at Week 10	Week 10	The primary outcome was a blinded rating of improvement of the treatment area (1064nm Q-switch Laser Versus Glycolic Acid Peels) using a Visual Analog Scale (VAS). A dermatologist blindly evaluated the treated areas of each side from live subjects at baseline on the final follow up visit (week 10). The VAS of improvement was rated on a scale of 0 to10, with 0 being no improvement and 10 being the most improvement seen by the treatment.
