Dr.Althea Vitamin C Boosting Serum

The Dr.Althea Vitamin C Boosting Serum earns a buy on the strength of three well-studied brightening and barrier actives—niacinamide, tranexamic acid, and sodium hyaluronate—alongside a centella asiatica leaf water base that adds clinically recognized soothing support. That's a lot of evidence-backed work packed into one serum.
