Combination Topical Cysteamine and Fractional 1927nm Low-Powered Diode Laser for Treatment of Facial Melasma

Study Overview
=================
Brief Summary
-----------------
The primary objective of our study is to determine the efficacy of combined topical cysteamine cream with a 1927 diode non-ablative laser (Clear + Brilliant Permea®; Solta Medical, Inc.), compared to topical cysteamine (Cyspera) alone in the treatment of melasma. The main questions it aims to answer are If melasma treatment with topical cysteamine cream is more effective when used with the Clear & Brilliant® Permea laser The safety & efficacy of melasma treatment in various skin types using the Clear & Brilliantt® Permea laser in combination with topical cysteamine. Participants will Come into our office for an initial screening appointment to determine if participant is eligible for the study Come in for 3 laser treatments, 4 weeks apart, on 1 side of the face Use the study provided Cyspera topical cream every day on the entire face for the 12 weeks on the study. Researchers will compare the side of the participants face not treated with laser to the side of the face treated with laser. The participants will be using Cyspera on both sides of their face.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Fractional 1927nm Low-Powered Diode Laser combined with Topical Cysteamine<br>One side of the face of participants will be randomized to receive fractional 1927nm Low-Powered Diode Laser in combination with topical cysteamine. There are 3 total treatments with the laser, in combination with using the topical cysteamine cream every day for the duration of the study (12 weeks) | Device: Fractional 1927nm Low-Powered Diode Laser<br>* Clear & Brilliant Permea® Laser used on the side of the face randomized to receive laser<br>Other: Topical Cysteamine<br>* Topical Cysteamine cream will be used on the entire face.<br>|
| Active Comparator: Topical Cysteamine Alone<br>The other side of the face that is not randomized to receive laser treatment will be subject to treatment with the topical cysteamine cream alone. Participants will use the topical cysteamine cream every day for the duration of the study (12 weeks). | Other: Topical Cysteamine<br>* Topical Cysteamine cream will be used on the entire face.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The primary objective of our study is to determine the efficacy of combined topical cysteamine cream with a 1927 diode non-ablative laser (Clear + Brilliant Permea®; Solta Medical, Inc.), compared to topical cysteamine alone in the treatment of melasma. | Photographic assessment by two blinded dermatologists will measure changes will assess improvement in melasma by modified Melasma Area and Involvement Index (mMASI). Total mMASI score ranges from 0 - 24, with a higher score indicating more involvement and/or severity of melasma | 12 Weeks |
