Improve the look of dull, lacklustre skin with the COSRX 5 PDRN Collagen Intense Vitalizing Serum, a lightweight formula that delivers powerful results. Powered by a five PDRN complex, including salmon, centella asiatica, rice, lactobacillus and sea grapes, the serum promotes a collagen-rich illusion over time. Its plumping blend works to firm and smooth the appearance of fine lines, while niacinamide lends brightening properties and adenosine soothes and hydrates the skin.
