Study, Skin Care || Turmeric for Hyperpigmentation and Wrinkles?

I am subscribed to tons of YouTubers, and one of them is Farah.  She has several videos discussing the effectiveness of turmeric against hyperpigmentation.  While I have not tried her homemade mixtures, I did view this is an opportunity to find any research on turmeric and hyperpigmentation.  What did I find?

• In one study, turmeric demonstrated effectiveness against hyperpigmentation and other UVB-induced skin damage in mice.  It specifically prevented the following: an increase in skin thickness, a reduction in skin elasticity, formation of wrinkles, and formation of melanin induced by chronic UVB exposure [1].  The mechanism by which turmeric accomplishes this is believed to be via the "inhibition of increases in metalloproteinase-2 (MMP-2) expression caused by chronic irradiation". 
• Curcumin, an active component of turmeric, "protects skin by quenching free radicals and reducing inflammation through the inhibition of nuclear factor-kappa B [2]".
