Green Tea Serum Showdown: Tested Organic Leaves vs. Aging...For Face & Hair! We’ve been comparing skincare serums, and our latest test subject is the Premium Grade Serum Anti-Aging Green Tea Extract. Derived from USDA Organic Green Tea Leaves, this 8 fl oz serum promises to revitalize both our faces and scalps. The packaging suggests cosmetic-grade excellence, and the ingredient list confirms its potency. We appreciate the organic certification, as it aligns with our preference for natural formulations. Applying it has felt lightweight and refreshing, without irritation. Initial results show a subtle brightening on the skin, while a regular scalp massage with the remaining product has lessened stubborn dryness. Though more time is needed to judge anti-aging effects fully, we’re impressed so far. Give this serum a try if you’re looking for a multi-tasking, organic boost.
