What it is: MAC Liptensity Lipstick is a brilliant lipstick formula that pushes the boundaries of color. What it does: MAC Liptensity Lipstick has a luxurious gelled base that melts on contact, providing fully saturated color with a satin finish in one stroke. Each lipstick holds enhanced amounts of pigment, resulting in extreme color intensity, clarity and vibrancy. It is long-wearing, too, and lasts for eight hours. How to use: For full-intensity color, apply directly from the bullet. Roll the lipstick up to smooth directly onto your lips. Its rich gel formula melts on contact, meaning you'll get full, even coverage in one stroke. Before applying color, perfect your pout with a lip primer. Style Name: Mac Liptensity Lipstick.
