Mattes - If you are using an eyeshadow base, we recommend you set it first. Especially before applying deeper shades, give them a quick swatch to familiarize yourself with the pigmentation. These highly pigmented shadows don't have to be swirled. Dipping your brush once will pick up plenty of pigment. Use a blending or shader brush for best results.
Duochromes - Apply with a dense brush or your finger. These metallic shadows perform great when used dry, but spraying your brush with setting spray can further enhance the shine. Avoid getting moisture into your eyeshadow pan.
