I Tested 6 Korean Eye Creams for Dark Circles After a Winter of Bad Sleep — Only These 3 Actually Work

Only three made a visible difference: COSRX Advanced Snail Essence for puffiness, Some By Mi Retinol Eye Serum for stubborn pigmentation, and Laneige Eye Sleeping Mask for overnight fatigue repair. The rest moisturized fine — but didn’t touch actual dark circles.
