Dark circles, fine lines and under eye puffiness are common signs of aging. As you get older, the thin skin around your eyes loses some of its elasticity, causing the appearance of fine lines. Tissue in your eyelids can weaken, which can lead to swollen or puffy eyes. “If you’ve noticed dark circles, it’s likely your skin tone or genetics at play, but lack of sleep can also be a factor,” explained dermatologist Dr. Doris Day. She suggests RoC® Retinol Correxion Eye Cream to help treat those signs of aging.
