### Where It Began

### The science was there. The practicality? Not so much.

That’s the realization **barrière co-founder Cleo** had after trying **medical transdermal patches for her own vitamin deficiencies**. But they were irritating, inconvenient, and bulky — not made for sustainable habits or realistic routines.

**barrière was born not just as a solution to the absorption problem but as a solution to the habit-building problem.**

And Cleo’s not alone: 86% of the U.S. population take supplements, but only half stick to their routine. The vision was to **make it as easy, enjoyable and effective as possible to build and maintain wellness routines**.

And now, **Cleo and her co-founder Alexa** have brought that goal to life with beautiful, easy-to-use patches that deliver vitamins safely and efficiently, without disrupting your day-to-day life.

**Thank you for making barrière a part of your wellness journey.**

## Clinically Studied, Science Backed

The way your patches are made matters.

### M.H.R.A. registered.

While labs in the U.S. aren’t required to be registered with the FDA, our production facility is registered with the M.H.R.A., the U.K. equivalent of the FDA. This helps ensure safety, quality, and efficacy of every batch we make.

### Clinically Tested.

All our ingredients are clinically tested with efficacy in gold standard trials. Also known as Randomized Control Trials, this method minimizes outside bias and influence.

### Hydrophobic.

We often use hydrophobic vs. hydrophilic versions of ingredients. Also known as fat-soluble, hydrophobic ingredients are able to be stored and later used by your body when needed.

### Micronized ingredients.

We keep our ingredient particle size under 50 microns — that’s slightly smaller than the diameter of a human hair. This size allows the ingredients to actually get through the skin barrier.

- ### Dear Dairy User Trial

This 2-week in-house consumer study evaluated the real-world impact of transdermal lactase enzyme patches. Participants self-reported on digestive symptoms after consuming dairy, including bloating, nausea, and gas. Results reflected that participants felt a decrease in all reported digestive symptoms after consuming a meal containing dairy. †

**84%** of participants rated the patch 4-5 stars †

† Individual results may vary.

- ### Parallel Pilot  Study: Efficacy of Transdermal Vitamin D Patches

This study evaluated the safety & tolerability of daily application of patented transdermal vitamin D patches over 8 weeks and assessed its time-level profile. Notably, the study saw the percentage of those classified as vitamin D deficient drop from 23% to 0%. Based on results, long-term (8 weeks) application of patented transdermal vitamin D patches was found to be safe.
