Under Dark CirclesEven though I don't use makeup at all, I'm still applying concealer under my eyes. I constantly work on the computer, drink a lot of coffee, don't get enough sleep, and wear contact lenses. All of these bad habits show up on my face and require attention even during my best skin days. Also, my skin is very dry and the under eye area is no exception. Therefore, I always make sure to use a concealer that not only covers dark circles but also hydrates the skin. Also, as I get older, I make sure to apply a good moisturizer to my under-eye area twice a day, so that the concealer doesn't cake under my eyes. My favorite: BENEFIT COSMETICS Fake-Up Hydrating Concealer is a perfect two-in-one product as it successfully conceals dark circles and smoothes the under-eye area. I also love the unique look of this product - it looks like a clear lip balm with a concealer middle. You can apply this lightweight product directly under the eye area, using your ring finger to apply pressure, and then lightly blend the product upwards. If you're new to the concept of concealer wardrobe, this product is definitely the one to start with. Also try: BECCA Under Eye Brightening
