Product Details

Cosmedix Serum 16 is an advanced, retinol-based night serum that transforms skin by reducing fine lines, evening tone, and boosting hydration. Featuring LG-Retinex, a microencapsulated retinol complex, it promotes skin renewal with minimal irritation, making it ideal for all skin types, including sensitive skin. Clinically shown to deliver real results—90% reported brighter, more even skin tone, 88% noticed firmer skin, and 75% saw fewer wrinkles—this serum is a powerhouse for anti-aging.

Infused with Sodium Hyaluronate and antioxidant-rich extracts, Serum 16 hydrates deeply, protects against environmental stressors, and improves the appearance of acne scars, dark spots, and hyperpigmentation. Its lightweight, gluten-free formula absorbs quickly, supporting collagen production and skin elasticity for a smoother, more radiant complexion.
