What Causes Dark Circles Under the Eyes
Dark circles often result from thin skin, blood vessel visibility, lack of sleep, dehydration, or genetics. Aging can also reduce collagen, making the area appear more shadowed. Understanding the cause helps you choose a targeted nighttime eye cream for dark circles that addresses specific concerns.
Key Ingredients in Nighttime Eye Creams
Effective formulas often include retinol, peptides, vitamin C, caffeine, niacinamide, or hyaluronic acid. Retinol supports collagen, while caffeine may temporarily reduce puffiness. For more details on ingredient functions, see this guide from the American Academy of Dermatology.
How to Use Nighttime Eye Cream Correctly
Apply a small amount to clean skin around the orbital bone, not directly on the eyelid. Use your ring finger for gentle tapping, and layer after serums but before moisturizer. Consistent nightly use, along with adequate sleep and hydration, supports a smoother, more rested appearance over time.
