Medicube Retinol Boosting Serum
Details
Medicube's Retinol Boosting Serum is a nightly firming treatment that pairs retinol and retinal with NMN, a next-generation booster, to work on the look of fine lines and slackness. Niacinamide brightens the appearance of dullness while a ferment complex of bifida, lactobacillus, and lactococcus lysates supports a healthy-looking, resilient finish. Macadamia seed oil, squalane, and a cholesterol-and-sterol blend cushion the formula so retinol feels comfortable rather than tight. The lightweight texture absorbs quickly and layers under a night cream. Skin looks smoother, firmer, and more refined with consistent use.
Key Ingredients
