barrière makes a variety of wearable wellness patches to support everything from energy and immunity to sleep, and Dear Dairy is a fresh addition to the brand's portfolio and a first-of-its-kind, fast-acting lactose relief patch.
These vegan and cruelty-free patches are waterproof, hypoallergenic and designed to deliver all-day lactose relief by continuously delivering enzymes that break down lactose in dairy products. As far as what to expect from the peel-and-stick experience, barrière shared that, in an in-home consumer study, 85% felt the patch working within 60 minutes and later, more than 85% felt little to no digestive discomfort even two to four hours after consuming dairy.
The Dear Dairy lactose relief patch is available in two prints: starry Milky Way and Milky Treats, featuring favorite indulgences like ice cream, butter, and milk.
