What this trial studies

This study investigates the effectiveness of the Aerolase laser treatment in conjunction with a topical depigmenting agent, Mela B3 cream, for patients with moderate to severe melasma. Participants will apply the cream twice daily for three months while receiving laser treatment on one side of their face every other week for a total of six sessions. The aim is to enhance the efficacy of the cream and reduce the intensity of melasma relapses by targeting both pigmentation and vascular components. The study will also include the use of a high SPF sunscreen to protect the skin during treatment.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 18 and older with clinically diagnosed moderate to severe melasma.

Not a fit: Patients with mild melasma or those who do not meet the inclusion criteria, such as those not using effective contraception if they are women of childbearing potential, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the frequency and severity of melasma relapses in affected patients.

How similar studies have performed: While there is limited data on this specific laser treatment for melasma, similar laser therapies have shown promise in managing hyperpigmentation disorders.
