Detailed Description

Melasma is an acquired chronic and relapsing hyperpigmentation disorder, with a significant negative impact on the quality of life of patients. Melasma is more common in patients with skin of color and has also been linked to chronic ultraviolet (UV) and heat exposure, family history and hormonal factors. There are several studies in the literature using various therapies for melasma, including sun protection, topical therapies, lasers and chemical peels. However, many of these studies vary greatly in their efficacies and side effect profiles, due to varying and undelineated pre and post-op procedure regimens. Side effects of post-inflammatory hyper and hypopigmentation and rebound are reported in these studies. The investigators would like to conduct a tri-split face study that compares a 22% trichloroacetic acid (TCA) deep medium peel with an ablative fractionated CO2 laser and more pigment selective Q-switched (Qs) Nd:YAG laser. To minimize possible post-procedure side effects and melasma rebound, the investigators will perform above treatments in conjunction with an optimal skincare regimen, starting 6 weeks before and continuing after the treatments. The investigators will perform the 22% TCA chemical peel, CO2 laser and Qs-Nd:YAG at 6 weeks after the start of the skincare regimen, and repeat treatments with Qs-Nd:YAG at weeks 8, 10, and 12. The investigators will assess participants using standardized photos in conjunction with UV imaging (Visia CR) at weeks 0, 6, 16, 20 and 24 (6 months), by measuring the modified melasma area and severity index (mMASI) scores and visual analog scale (VAS) scores as graded by participants as well as by blinded physicians based on photos and UV imaging.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: 22% TCA peel
22% trichloroacetic acid medium depth chemical peel applied to one of the three facial areas (based on random assignment- forehead, left cheek, right cheek)
Drug: 22% TCA peel
One of the three facial areas (based on random assignment- forehead, left cheek, right cheek) will be treated with one treatment with a 22% TCA Blue Peel, to achieve a level 2 frost (medium depth peel). Each treatment will take about 20 minutes. A 22% TCA concentration will be created by combining 5.5 mL of 30% TCA (from a purchased commercial bottle) with 2mL of blue dye (commercial), immediately before application.
Other Names:
  • medium depth chemical peel
  • TCA peel
Active Comparator: CO2 laser
CO2 ablative fractional laser resurfacing applied to one of the three facial areas (based on random assignment- forehead, left cheek, right cheek)
Device: CO2 laser
One of the three facial areas (based on random assignment- forehead, left cheek, right cheek) will receive one treatment with one pass of the fractionated ablative 10,600 nm CO2 (CO2RE Laser, Syneron) at Core 70 mJ, Ring 50mJ, 40% coverage, 1 pass, 8 mm square pattern. Each treatment will take about 20 minutes.
