Clinical Trial Summary

Melasma is an acquired hyperpigmentation disorder with a multifactorial etiology and complex pathogenesis that can significantly diminish the quality of life for affected patients. As of now, melasma therapy remains challenging due to its high recurrence rate and the common occurrence of treatment-related side effects. The use of depigmentation agents is a crucial component in managing melasma. Hydroquinone stands as the first-line depigmentation agent for melasma; however, its use often leads to adverse effects. Therefore, alternative depigmentation agents are needed. Curcuma xanthorriza Roxb., a native plant of Indonesia, operates by inhibiting the tyrosinase enzyme, reducing MITF transcription, and inhibiting α-MSH. Despite these potential benefits, Curcuma xanthorriza Roxb. has not been utilized as a depigmentation agent. Research on the effectiveness of Curcuma xanthorriza Roxb. as a depigmentation agent in melasma treatment has not been conducted. Therefore, it is essential to conduct research to determine the effectiveness of a 10% Curcuma xanthorrhiza Roxb. cream in reducing MASI scores and enhancing skin brightness in epidermal-type melasma.

Clinical Trial Description

Curcuma xanthorrhiza Roxb., known locally as temulawak in Indonesia or koneng gede in Sundanese, is a member of the Zingiberaceae family and is native to Indonesia. Previous research related to Curcuma xanthorriza Roxb. and its impact on melanin synthesis was conducted using mushroom tyrosinase by Batubara et al. The study found that methanol extract of Curcuma xanthorriza Roxb. could decrease tyrosinase enzyme activity with an inhibition concentration 50% (IC50) of 0.27 mg/mL.

Research conducted by Lee et al. on curcumin from another Curcuma species, C. longa or turmeric, demonstrated that curcumin reduced melanin quantity, tyrosinase enzyme activity, and micropthalmia-associated transcription factor (MITF) protein. In an in-silico study, Mustarichie et al. reported that the three active compounds in Curcuma xanthorriza Roxb. could inhibit both tyrosinase enzyme and α-melanin stimulating hormone (α-MSH). Xanthorrizol exhibited the most effective interaction with the tyrosinase enzyme, while demethoxycurcumin showed the most effective interaction with α-MSH.

Up to this point, there has been no research on the effectiveness of 10% Curcuma xanthorriza Roxb. cream in treating melasma. Therefore, the researchers are motivated to investigate the efficacy of 10% Curcuma xanthorriza Roxb. cream as a depigmentation agent, based on the assessment of MASI scores and skin brightness levels in patients with epidermal-type melasma using split-face therapy. ;
