Target	Human Endogenous Metabolite
In Vitro	Retinyl palmitate has a high molecular weight and a stable formulation. To be active, Retinyl palmitate should be enzymatically converted in the skin to retinol by cleavage of the ester linkage and must then be converted to tretinoin via oxidative processes[1].
In Vivo	The topical administration of Retinyl palmitate in rats results in increased protein and collagen and an epidermal thickening[1].
