Circulating levels decline with age, from roughly 200 ng/mL at age 20 to about 80 ng/mL by 60. Small split-face human dermatology studies, usually with fewer than 50 participants per arm, report changes in wrinkle depth and skin density

Notably, in these studies, the upregulation of GPx4 has been achieved by using exogenous agents (like NVP-AUY922, Bafilomycin A1, PD151746, GsMTx4, epigallocatechin-3-gallate, total flavonoids of Engelhardia roxburghiana leaves, Lycium barbarum polysaccharide-glycoprotein, perillaldehyde, melotonin, ferulic acid, and sphingosine-1-phosphate) which either inhibit the degradation of GPx4 or increase its transcription by activating the Nrf2 [67]
