The best eye creams for dark circles contain ingredients like caffeine, niacinamide, or vitamin C, which help improve microcirculation and brighten the under-eye area. A good Korean eye cream should also be lightweight for easy absorption.

In your 20s, focus on lightweight hydrating formulas with hyaluronic acid. In your 30s, choose products with antioxidants, and in your 40s and beyond, go for creams with peptides and retinol to combat wrinkles. Korean eye creams often provide multifunctional solutions suitable for all ages.
