TruSkin
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.
Pairs a plant-derived retinol alternative with squalane specifically to offset the dryness that makes many people abandon retinoids in the first two weeks.
