Lip products such as lipstick, lip liner, and lip gloss can be used to accentuate and balance the lips. Lip liner defines the lip line and comes in various shades that can match the lipstick or create a more defined look. Lipstick contains ingredients like wax, oil, and pigment to color the lips, and may include SPF. Lip gloss gives lips a shiny appearance and can make lips look fuller. It comes in different colors and tints and is often worn over lipstick.
