If you've been noticing that your under-eye concealer ends up enhancing your fine lines...you're not alone! The first thing you want to do is make sure you are using a concealer that has a moist (versus matte/dry) finish. We love these ones by Ellis Faas if you need a new one to try out. The moist finish will definitely help diffuse the appearance of fine lines. The second thing you want to do is focus on applying the concealer ONLY where the darkness is--typically under the inner corner and middle of the eye. Most fine lines congregate around the outer edge of the eye, and luckily for you, there's typically not much discoloration there. You really don't need to apply concealer anywhere except where the actual darkness is, so avoid putting concealer where it might cause trouble.
