SerumsBe the first to rate it

A high-concentration serum featuring 2.5% pure retinol balanced by niacinamide and hyaluronic acid to address fine lines and texture. This is a serious strength for an over-the-counter formula, making it a smart choice for those already well-acquainted with retinoids. Because it's potent, it rewards a patient approach—just a drop or two a few nights a week is enough to see the resurfacing benefits without unnecessary dryness.
