The Tam formula: A pilot study for a new treatment for melasma.

Background: Melasma is a common hyperpigmentation disorder with numerous, but often unsatisfactory treatment options. Aims: A pilot study to evaluate the efficacy and safety of a novel topical combination of 12% hydroquinone, 6% kojic acid, and 5% vitamin C cream for melasma. Patients and Methods: A pilot study of 6 women with melasma was conducted at an academic dermatology department and a private dermatology practice to evaluate the efficacy of a topical combination of 12% hydroquinone, 6% kojic acid, and 5% vitamin C cream, entitled the "Tam Formula." Two blinded evaluators calculated Melasma Area and Severity Index (MASI) Scores before and after treatment to evaluate change from baseline, and statistical analysis was performed. Results: Treatment with this combination topical cream resulted in an average 63.77 ± 22.10 percent reduction in MASI scores. Conclusions: While there is a need for further investigation, this pilot study indicates the Tam Formula may provide an alternative treatment option for melasma. [ABSTRACT FROM AUTHOR]
