Concentrated Firming Serum

As an Amazon Associate, Kit.Club earns from qualifying purchases.

A medical-grade retinol serum formulated with a lipid complex of phospholipids and glycolipids to target fine lines, enlarged pores, and dark spots. Glycine soja oil and lecithin provide a hydrating buffer that helps mitigate the dryness and irritation often associated with high-potency vitamin A. Retinol is the gold standard for firming, but it can be notoriously finicky; this formula balances that power with essential lipids to keep things steady. This one rewards those seeking the results of a concentrated treatment without the typical peeling or redness.
