Eye cream: which ingredients work and how to use them properly

The most effective eye creams contain retinol to reduce wrinkles, vitamin C to brighten dark spots, hyaluronic acid for hydration, and caffeine to reduce puffiness and dark circles. The product should be applied gently with the fingertips in circular motions, without rubbing. Gel formulas suit puffiness, while richer creams work better for dry, lined skin.
