Fillers are having what we like to call a mo-ment. Injectables are conquering new anatomical territory every week — from nipples to ear lobes — so it was only a matter of time before they hit the, er, booty. Here’s what you need to know about the non-surgical butt-lift.

Given the number of injectables filling up our social media feeds, it’s no surprise the 2016 Plastic Surgery Statistics Report from the American Society of Plastic Surgeons (ASPS) lists a steady increase in the use of syringes filled with plumping formulas. Now, plastic surgeons are noting an increase in the use of Sculptra — a poly-L-lactic acid that plumps by stimulating your body’s own collagen production — as an alternative to surgical butt-lifts.

“There has been a huge request and demand for gluteal augmentation including fillers,” Jaime S. Schwartz, a Beverly Hills-based plastic surgeon and RealSelf contributor, tells Allure.
