Derma Decode Advanced Age-Defying Retinol Serum For Face is an advanced night-use facial serum designed to support visible anti-ageing care, smoother texture, and firmer-looking skin. It helps improve the appearance of fine lines, wrinkles, dullness, and loss of firmness by supporting skin renewal with a gradual-use routine. The serum should be applied to the face, neck, and décolletage with gentle upward and outward massage, followed by moisturiser over the treated area. Ideal for mature or ageing skin concerns, it should be started only twice a week and increased gradually as tolerated, with sunscreen used the next morning.
