This rush of blood to the area can also cause the melanocytes, our pigment producing skin cells, to go into overdrive, causing post-inflammatory hyperpigmentation, or dark spots, which in some cases can be permanent. Is fuller lips for a few hours or days worth having darkened skin on your upper lip that resembles a mustache? Bruises? Broken blood vessels? Scar tissue?

Products already exist to plump up lips by gently increasing blood flow to the area, usually with ingredients like cinnamon in small concentrations. Don't ruin your face!

The newest "challenge" on the internet is to use suction to force blood into your lips, causing them to swell, mimicking Kylie Jenner's plumped up pout.

Kylie Jenner claims that she has not had any plastic surgery, a claim that seems ludicrous when comparing photos of her from 2014 and 2015. Overdrawing lip liner can create the illusion of fuller lips, but it does not actually increase volume and fullness, which is clearly evident, and appears to be the result of injections.

All over every social media platform, are videos and photos of people, mostly young women, using specialty suction cups, shot glasses, soda bottles, and practically every other round object they can find to plump up their lips, mostly ending in either hilarity or disaster.

The suction causes blood and other chemicals to rush to your lips, engorging the tiny blood vessels. If the suction is done for too long, it can burst these blood vessels, causing permanent damage, or even clots. A shot glass can also burst from too much pressure, since glass is not flexible. Shattered glass can cause a giant bloody mess.

The fragile skin around the lips is also affected, usually with mild to severe bruising. This bruising can last for days; on sensitive skin, it could last for weeks.
