firming serum

The botanically based body treatment that refines skin tone and texture.

Written By JAYME CYK


Fitness expert Christine Bullock and former lawyer and beauty maven Carrington Snyder have been slathering La Mer all over their bodies since college. And when the duo set out to create their own body range, they were inspired by face-grade skincare—that is, products formulated specifically for the complexion containing active ingredients that are traditionally not incorporated into body creams, oils, and serums. The final result? Kayo Better Body Care, a line of five all-natural products infused with active ingredients (think: coenzyme Q10, vitamin K, hyaluronic acid, and copper peptides, among others).

Naturally, one of their hero products is best known as the Concentrated Firming Serum, a botanically based formula infused with hyaluronic acid, a blend of omega oils, and caffeine. The fragrance-free, fast-absorbing formula helps to refine, firm, tighten, and smooth out your physique. “Carrington and I call this our pick-me-up product,” says Bullock. “We use it when we’re showing some skin (whether at an event or just by the pool), prior to plane rides, and on long workdays or any occasion when we want to feel our best.”


“You feel a tingling sensation after application, which feels a bit cool but refreshing. I love that it’s a body serum.”—Carola Gonzalez, makeup artist

“It’s nice because you can focus on specific areas. The motion of working on those areas gets the blood moving and makes you do something you normally wouldn’t do.”—Jo Strettell, makeup artist


Spot treat problem areas, such as thighs, buttocks, arms, or under the neck, or apply all over the body. Bonus points if you apply it before a workout—see below for Bullock’s four-step tutorial on getting a great summer butt. Your bikini bottoms will thank you.
