Is This The End Of Kylie’s Trademark Lips?

Kylie Jenner’s trademark lips could be no more.

The 20-year-old reality star, who is expecting her first child with boyfriend Travis Scott, admitted to getting “temporary lip fillers” on a 2015 episode of “Keeping Up With the Kardashians,” but now that she’s expecting, doctors say she may have to leave her plump pout behind.

“I recommend that women stop getting lip fillers as soon as they learn they are pregnant,” Dr. Simon Ourian, a cosmetic and plastic surgeon who has worked with Jenner, told Page Six.

“No one knows the implications of lip fillers on pregnant patients since dermal fillers haven’t been tested on pregnant women.”

Although he may be approached by pregnant women looking to have work done, Ourian has a strict policy about not giving lip injections to those with child.

“I would never knowingly administer lip injections to a pregnant patient,” he said. “In fact, it is my policy not to perform any procedures at all on pregnant women.”

Despite not being able to visit Dr. Ourian while she’s expecting, there’s a good chance Jenner’s pucker will stay put.

“If a woman receives lip fillers before becoming pregnant, the results can last several months into her pregnancy, especially if she received one of the newer longer-lasting fillers,” he said. “Additionally, many women experience naturally increased lip size during pregnancy due to increased levels of estrogen, blood flow, fluids, and swelling caused by pregnancy, regardless of whether they ever received lip fillers previously.”
