Dermatologists suggest that choosing the right under-eye cream can help reduce puffiness and dark circles by addressing specific causes. Pigmented circles may benefit from ingredients like Vitamin C or Niacinamide, while vascular circles can be improved with caffeine or Vitamin K. For shadowing due to aging, hyaluronic acid and ceramides are recommended. Selecting a cream based on ingredient quality and individual concerns is key for brighter, smoother under-eye skin.
