Firstly to ensure that this has the longest effect on your eyes ensure that you put foundation and blend it in and dust powder over it. This eliminates that crease that was mentioned in the post.
Secondly a blending brush is so important when applying eye shadow and MAC has the best blending brush. Apply the eyeshadow and BLEND BLEND BLEND. This ensures there are no harsh edges and it is smooth and perfect all day long.
