A) Viability of HaCaT cells after treatment with XH for a duration of 48 h; B) Melanosome degradation assay in HaCaT cells treated with synthetic melanin (for 48 h) followed by treatment with XH at various nontoxic concentrations for another 48 h with corresponding panel showing photos of cell pellets; *p < 0.05; **p < 0.01 and #p < 0.001 compared to control; One-way ANOVA followed by Dunnett's test; All data is representative of Mean ± SD of one out of two independent experiments with n = 3 per group.
