Like a fresh blowout, a perfectly polished manicure has its own way of instantly making a woman feel a bit more ladylike. So when deadline-driven, high-stress periods roll around, it’s only a matter of time before my awful nail-biting habit surfaces and I begin to feel less than my best when I should be running at full-throttle. I’ve searched high and low—and tested many a product along the way—for any remedy I can to curb the habit, but all with no avail.

When Dermelect Cosmeceuticals’ new Resist Nail Bite Inhibitor + Restorative Treatment ($15) formula hit my desk just in time for me to swipe on a coat before my latest deadline hit, I couldn’t be more hopeful (the brand boasts the first peptide-infused nail treatments that have never let my fingertips down before). While the formula’s ingredient list had me hooked before I opened up the bottle—it’s packed with keratin peptides, vitamin E, calcium, and of course, garlic extract—the results quickly sealed the deal.

Aside from it successfully stopping all nail biting in its tracks (the taste is a serious deterrent), the polish goes on crystal clear and is the definition of a multitasker. Use it as a base or topcoat to any of your favorite hues, as a nail treatment to strengthen and restore nails and cuticles, or as a nail-growth miracle worker to get your tips longer, quick. After wearing the polish under my go-to pinky-nude polish for one week, my nails were significantly longer, less brittle and way tougher than pre-application. When it comes to finding a nail treatment that seriously does it all and curbs a nail-biting habit, look no further—this one delivers.
