The downturned eye is where the inner corner of your eye is higher than the outer corner. To really accentuate this eye shape you will want a lash that focuses on lifting the outer corner to really allow the eyes to pop! A nice outer curl will help lift the outer corner of the eye. The best Method Lash styles to dress up the downturned eye are Optimist, Cherish, The Dream - they allow for a longer more curled outer edge.
Other lashes that compliment this eye shape are Vixen, Influence and Scandal.
