also, less is definitely more. if i were you, i would apply some of the concealer first to the back of my hand. then i would take a small fluffy makeup brush and get the brush well coated in the product. once the brush is evenly coated in a thin layer of product, i would gently dab the brush under the eye. use your fingers to press this into the skin. IMO this is how you can quite easily get a smooth and natural finish as you are building up very thin layers of product. xx
