How Do Lip Plumpers Work?

How Are Lip Plumpers Formulated?

Because lip plumpers are a part of the lipstick family, they are formulated in a similar way, but Rosario notes that there is one main difference: the addition of plumping ingredients. “Plumping ingredients such as capsaicin are included as well as hydration ingredients to improve the overall look of the lips and high shine for a volumized lip look,” she says. The plumping ingredients are included at specific concentrations to ensure their safety.

What is the Main Ingredient in Lip Plumpers?

Hyaluronic acid, peppermint, cayenne pepper, and jojoba oil are often infused into lip plumpers to give lips that tingling sensation. Capsaicin is also often used, which is a compound found in hot peppers, as well as ingredients like peppermint and ginger that also cause a similar effect. “The tingling sensation is from these ingredients, and it indicates that they’re working,” Rosario adds.

These ingredients are key in building lip plumpers differently from regular lip products. According to Rosario, “Lip plumpers contain active ingredients that cause plumping, which a normal lipstick does not contain. Most plumping ingredients work by causing a temporary mild irritation of the lips.”

Are Lip Plumpers Safe?

The ultimate safety of your favorite beauty products will depend on the brand you purchase from and their individual testing. Lip plumpers created by L’Oréal Paris, as with any other beauty product, are thoroughly tested for safety and claims. “Tests are performed to ensure that the plumpers are safe to use and would not cause undesirable side-effects to healthy individuals using the product recommended,” says Rosario. The lip plumpers are also tested for efficacy — to ensure that they really work.

Why You Should Never DIY a Lip Plumper

While lip plumping is meant for mild, temporary irritation, Rosario warns against trying a DIY version at home. “People interested in lip plumping should choose a product from a reputable brand, because DIY-ing a lip plumper without knowing the right concentration of an active ingredient and safety testing can cause mild irritation to turn into a serious effect,” she says.
