Behind barrière: Our Why
We believe daily wellness should be effortless. With science-backed formulas held to the highest safety standards, our patches are made to seamlessly slip into your day. Just peel and stick — no complications, no compromises.
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
If properly made, transdermal patches can offer 6-10x the absorption rate of oral vitamins.*
That means using:
- Micronized ingredient particle sizes under 50 microns.
- Hydrophobic vs. hydrophilic versions of specific ingredients.
- Clinically-tested ingredients with efficacy in gold standard trials.

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.

Clinical Study: Transdermal Patch Delivery of Vitamin B12 as Alzheimer’s Treatment Method
As a potential treatment approach for Alzheimer’s Disease, a transdermal drug delivery system (nanofibers) was designed to deliver donepezil & vitamin B12. Data showed that nanofibers are a promising alternative for treatment. A transdermal patch would provide a non-insanve option and exhibits relatively few side effects compared to conventional therapy.
