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.
Retinal requires one less conversion step than retinol to become active in skin, making 1% retinal roughly equivalent in potency to a much higher percentage of retinol.
