Lip gloss is a product used primarily to give lips a glossy lustre, and sometimes to add a subtle color. It is distributed as a liquid or a soft solid (not to be confused with lip balm, which generally has medical or soothing purposes) or lipstick, which generally is a solid, cream like substance that gives off a more pigmented color. The product is available in ranges of opacity from translucent to solid, and can have various frosted, glittery, glossy, and metallic finishes.
Like lipstick, lip gloss comes in a variety of forms and may be applied in different ways. It can be contained in a small cylinder and applied with a rounded or sloped applicator wand (known as a doefoot applicator) or with a built in lip brush. It can come in a small, soft, squeezable plastic tube designed to be passed over the lips or applied with a fingertip or lip brush. Solid or semisolid glosses come in boxes or tubes and sometimes blur the distinction between lip gloss and lip balm.
Basic lip gloss: adds basic shine to your lips without color. Colored lip gloss: adds a combination of color and shine. Glittery lip gloss: can be with or without color, but has a glitter base.
New types of "plumping" lip gloss contain ingredients that make the lips appear softer and plumper. These are a cheap, easy, and usually harmless alternative if compared to collagen, Restylane, Juvederm, or fat injections. They are not as effective, however because the effects are temporary.
Lip gloss is often used when a person wants to have some color on their lips, but does not want an intense, solid lip color effect (i.e., a more "made-up" look), as lipstick would create. Lip gloss is also often used as an introduction to makeup. It is often used by preteen and young teenage girls who want to wear some makeup, but are too young to wear more intense lipstick colors. Lip gloss is also common for young women who don't like to wear makeup but have to attend a formal occasion. Lip gloss can be applied on top of lipstick to increase the gloss of a color, or to add depth as in the case of glitter gloss.
Like lipstick, lip gloss is a mixture of waxes, oils, and pigments. However, lip gloss contains less pigments, and those used are often pale in color or diluted (<3%). Furthermore, the free-flowing nature of the product requires less wax. The principal components are lanolin, which feels good on the lips due to its moisturizing qualities and imparts gloss, and polybutene.
