Cushion foundation is a makeup format, not a serum. You press a puff into a soaked sponge inside a compact and tap coverage onto the face—usually sheerer than a liquid bottle, with a skin-like finish that is easy to touch up from a bag.
If you want a bottle you pour, this is the wrong aisle. If you want a compact that lives in a tote and a finish that still looks like skin, compare undertone first, then how the puff lays product around the nose and mouth.
