This property interests those seeking to address hyperpigmentation caused by UV exposure and other environmental factors

Other studies had significant results, but typically by using tremendous amounts of supplements and/or combining oral supplements with injections or transdermal skin patches (21, 22)

To further explore the substrate scope of arGSTs, additional yeast systems were engineered using a one-plasmid strategy containing genes encoding dihydroflavonol-4-reductase (DFR), LDOX, a range of arGST and non-arGSTs (as negative controls) and anthocyanidin-3- O -glucosyl transferase (A3GT) (Fig
