TruSkin Vitamin C Serum
A budget-accessible vitamin C serum — worth checking the ingredient list for stabilizers like ferulic acid, since pure L-ascorbic acid degrades quickly once opened.
Combines vitamin C with glycosaminoglycans, adding a hydration-focused layer to what's usually a purely antioxidant-focused formula category.
