What ingredient should I look for in an eye cream?

It depends on your concern. Reviewers gravitate toward caffeine for puffiness and tired-looking eyes, retinol or retinal for fine lines and crow's feet, peptides and niacinamide for general anti-aging support, hyaluronic acid for hydration, and vitamin C for brightening. Several products here, such as the CeraVe Skin Renewing cream, combine peptides, caffeine and niacinamide in one formula.
