Background
Melasma—a localized chronic acquired hypermelanosis—is common in adult women and it is difficult to treat.
Aims
We designed a pilot, uncontrolled open‐label study to evaluate the appearance of epidermal melasma after 6 months of twice‐daily application of a nonprescription proprietary gel formulation containing glabridin, andrographolide, and apolactoferrin.
Patients/Methods
A total of 40 Caucasian women with epidermal melasma (Fitzpatrick skin types II‐VI) were enrolled. The study endpoints included standardized clinical photography, determination of Melasma Area and Severity Index (MASI) scores, spectrocolorimeter X‐Rite analysis, in vivo reflectance confocal microscopy (RCM), and self‐assessment of cosmetic acceptability.
Results
All endpoints showed a statistically significant improvement of epidermal melasma from baseline to the end of the study. There were no dropouts and cosmetic acceptability was rated as excellent by all of the study patients. The only observed adverse event was a mild, transient xerosis (n = 3).
Conclusions
Favorable outcomes, as demonstrated by investigator and instrumental assessments, were demonstrated using a proprietary gel for the treatment of epidermal melasma in adult women. Our results need to be confirmed in independent placebo‐controlled studies.
