This Jaw-Sculpting Serum Has Sold Out 3 Times But It's Finally Back In Stock

Our beauty editors don’t give out praise lightly—so when I heard one raving about a neck-firming serum with results so good they made her gasp, I knew this product was no joke.

The ShapeShift V-Line Jaw Defining Serum uses exosomes to alter your skin on the cellular level, reducing the appearance of wrinkles and crepey skin, and creating a more sculpted neck and jawline. And in case you’re feeling skeptical, biotech beauty brand SickScience has science (and some very impressive before and after photos) to back it.

The serum has sold out multiple times since the initial launch in March, but it’s back in stock and I finally got my hands on it. Don’t miss your chance to do the same.

For starters, the founders Polen Koçak, Ph.D., and Merve Yildirim, Ph.D., are (literally) molecular scientists, so you know they’re meticulous in creating each formula.

Rather than a harsh or potent exfoliator, ShapeShift uses exosomes (compounds extracted from plant-based stem cells) to harness the power of your DNA and encourage a smoother, more contoured neck area. 

I’ve only used the serum for about two weeks, but I love that it’s lightweight, non-irritating, vegan, hypoallergenic, and fragrance-free. Plus it’s simple to integrate into my existing skin care routine.

Of course, seeing and hearing about other people’s results is what’s really keeping me consistent with the serum. In a third-party clinical study of 31 volunteers for eight weeks, 90% of participants reported increased firmness of the skin, and 94% said their skin felt smoother after using the serum.

Our aforementioned senior beauty editor, Jamie Schneider, said the serum made her neck and jaw look “more defined than ever” after about four weeks of testing the serum.

Thanks to its unique ingredients, the ShapeShift jaw-defining treatment sold out quickly after launch—and twice more since the initial restock. Now it’s back in stock for a third time (though not for long if history is any indication).
