Part of TonyMoly's Inkey Library ampoule series, this collagen-focused treatment targets fine lines and loss of firmness for a plumper, smoother-looking complexion. The lightweight, fast-absorbing formula features hydrolyzed and fermented collagen alongside Matrixyl (Palmitoyl Pentapeptide-4) to support the skin's natural collagen production, plus sodium hyaluronate for deep hydration and vitamin E for antioxidant protection. Gentle enough for most skin types, it's best suited to those starting to notice fine lines, sagging, or dullness and wanting extra firming support in their routine. After cleansing and toning, pat a few drops onto face and neck, then follow with moisturizer (and sunscreen in the morning). Use morning and night for continued anti-aging support.
