Collagen Pro Patches combine vitamin C, Tremella mushroom, blueberry extract, black tea extract, seaweed extract, and amino acids in a simple patch applied directly to the skin. Once in place, the patch delivers nutrients gradually into the bloodstream for 6–8 hours, bypassing digestion for steady absorption.

Formulated with vitamin C, which contributes to normal collagen formation for the normal function of skin, cartilage, bones, gums, teeth, and blood vessels, the patches also help protect cells from oxidative stress. Alongside botanical and amino acid extracts, this transdermal delivery method provides a practical way to include these nutrients in a daily routine as part of a varied diet and balanced lifestyle.

WHAT’S THAT PATCH uses advanced transdermal technology to deliver carefully selected, science-backed ingredients directly into the bloodstream, bypassing digestion for consistent absorption. Each patch is crafted with three layers: a protective backing to lock in freshness, a transdermal matrix containing active nutrients, and a gentle medical-grade adhesive designed to be kind to skin. This structure ensures a steady release of ingredients while remaining comfortable and easy to wear. Made without parabens, synthetic fragrances, or harsh additives, and never tested on animals, the patches combine effectiveness with ethical wellbeing.

WHAT’S THAT PATCH was born from a belief that wellness should feel natural, simple, and effective. Inspired by ancient practices like Chinese herbal plasters and Ayurvedic remedies, the brand reimagined these traditions with modern transdermal technology. Each patch is formulated with carefully selected, science-backed ingredients, delivered directly through the skin for steady absorption. With a mission to make routines effortless and meaningful, WHAT’S THAT PATCH offers a thoughtful way to support balance in everyday life. Through this gentle yet precise approach, the brand helps you embrace small, lasting changes that keep you feeling more like yourself.
