Cell viability (MTT assay), tyrosinase activity (L-DOPA assay), and melanin content were measured. &lt;strong&gt;Results:&lt;/strong&gt; GC-MS identified 9,12-octadecadienoic acid methyl ester (E,E) as the predominant compound (45.88%), while HPLC confirmed a relatively low TQ concentration (0.04%). EE BCS maintained &amp;gt;90% cell viability at concentrations up to 12.50 ppm and exhibited an IC50 of 56.41 ppm. Tyrosinase activity significantly increased at 6.25 ppm (136.40%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.05) and 12.50 ppm (228.10%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.01), accompanied by a significant elevation in melanin content (226.00%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.05 and 266.90%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.01 respectively). &lt;strong&gt;Conclusion: &lt;/strong&gt;EE BCS can effectively promote melanogenesis, despite containing low levels of thymoquinone, potentially through synergistic actions of its phytochemical constituents. Given its region-specific phytochemical richness, Indonesian &lt;em&gt;N. sativa&lt;/em&gt; extract holds promise as a natural therapeutic candidate for vitiligo. Further &lt;em&gt;in-vivo&lt;/em&gt; and clinical validation is warranted.&lt;/p&gt;
