The top-rated BareMinerals Gen Nude Under Over Lip Liner ($16) or BareMinerals Statement Under Over Lip Liner ($16) get that name because each can be worn under or over the lipstick of your choosing, be it a bold colour or something more flesh-toned. Either way, you start priming and defining lips, and then refine the shape after you've applied lipstick so everything stays in bounds.
