This Lip Plumping Hack Is Going Viral But Is It Safe? We Asked A Derm


Cinnamon is a spicy, heat-inducing essential oil that acts as a vasodilator (meaning, it can stimulate your blood vessels and cause them to expand). 

“A vasodilatation forces the capillaries, or smaller blood vessels (of which there are many in our lip tissue), to open and therefore allow more blood and fluids to push through and even expand beyond the vessel wall into membranes and other tissues,” says board-certified dermatologist Ava Shamban, M.D., founder of Ava MD Dermatology, the SkinFive and The Box by Dr. Ava. It’s this stimulation that creates a localized “swollen” appearance and a plumper pout as the fluids leak past the vermillion border.  

In other words: Yes! Cinnamon oil can plump your lips temporarily. In fact, plenty of market lip plumpers incorporate the essential oil into their formulas, along with other stimulating EOs like peppermint. “Even [traditional] products use these ingredients for their properties,” naturopathic doctor Tess Marshall, N.D., told us about how to naturally plump your lips. 

You can also take the DIY route, as shown in Miller’s video, by finding a clear lip gloss of your choice (this jelly from Tower28 is super shiny), and combining it with three drops of cinnamon oil in a small dish. Mix using the wand, apply on your lips, and wait a few minutes for the cinnamon oil to work.
