Dark Circles
Dark circles can be caused by smoking, sleeplessness, or too much alcohol or caffeine. In other words, by being an adult. As we age, we lose collagen, which in turn makes blood vessels more prone to breakage, which causes dark circles under your eyes. In addition to making obvious lifestyle changes, Gross recommends using products with vitamins K and C, and retinoids that help build collagen, like RoC Multi-Correxion Eye Treatment ($19.99).
