PATCHES
Why Barrière patches?

Our patches provide a fun, convenient, and effective alternative to oral vitamins and supplements, seamlessly integrating into your daily routine. Whether you have trouble swallowing pills, need a travel-friendly option (they're easy to pack!), or want to start or enhance your vitamin regimen, our patches offer the perfect solution.

Each patch delivers vitamins transdermally, allowing direct absorption into the bloodstream for increased efficacy compared to pills. With a sustained release of ingredients over 8–12 hours, our patches provide both instant benefits and long-lasting results.* Just one patch a day is all you need—without fillers or questionable ingredients.

Thoughtfully formulated with 100% plant-powered ingredients, our patches support overall health, skin vitality, and daily wellness. We prioritize quality with third-party testing and certified lab verification to meet the highest wellness standards. Plus, our patches are recyclable, water-resistant, and, of course, stylish.

How do transdermal vitamin patches work?

Transdermal vitamin patches offer an innovative, hassle-free alternative to traditional vitamins and supplements. Designed for convenience, they provide an effective way to get the vitamins your body needs without disrupting your daily routine. Traditional vitamins have to pass through your digestive system before your body can absorb them—but transdermal patches work differently. Our innovative patch technology delivers vitamins and adaptogens directly through the skin and into the bloodstream, bypassing the gut for enhanced absorption.

Each patch is designed for a sustained release of ingredients over 8–12 hours, ensuring a steady, consistent dose without spikes or crashes. Simply apply the patch to clean, dry skin, and let it do the work—no pills, no water, no digestion required. Whether you're on the go, have trouble swallowing pills, or just want a more efficient way to supplement your routine, our patches provide a seamless, science-backed solution for daily wellness.

Why choose patches over pills?

Capsule-based vitamins can lose over 90% of their efficacy during digestion, and nearly 40% of the U.S. population struggles with swallowing pills.2 Oral supplements often require multiple doses per day, and some ingredients need larger serving sizes than a capsule can hold. Pills aren’t designed for instant results and can cause side effects like nausea while potentially containing fillers or questionable ingredients.

In contrast, our transdermal patches provide a convenient, effective alternative with optimal absorption, steady release, and no unwanted additives. Plus, unlike other patch brands, ours are thoughtfully formulated, stylish, and fully recyclable—because wellness should be both effective and enjoyable.

Are patches effective?

Yes—when formulated correctly by a reputable source. Our patches are produced in a U.K. facility registered with the M.H.R.A. and ISO 9001 certified, ensuring high-quality manufacturing standards. We also work with third-party testing partners to verify that the ingredients and dosages in our patches meet our exact specifications.

For a patch to be effective, the particle size of each ingredient must be small enough to pass through the skin and underlying tissue for systemic absorption. This is achieved by optimizing each ingredient’s aqueous solubility and permeability—the more soluble the material, the more effectively it can be absorbed transdermally. We use micronization to reduce particle sizes to under 50 microns, ensuring maximum absorption and efficacy.

Our patches are specifically designed to deliver essential vitamins through the skin without any unnecessary fillers or additives—so you get exactly what you need, nothing you don’t.

Are Barrière patches third-party tested?

Where and when should I apply my Barrière patch?

Patches should be applied to clean, dry skin. Avoid placing patches on your face, head, or any areas with broken or irritated skin. Some of the best spots for application include the inner and outer wrists, upper arms, shoulder blades, collarbone, upper and lower back, hips, thighs, and ankles. For best results, apply the patch to an area with little to no hair, such as the wrist, shoulder, back, or hips, while avoiding particularly sensitive areas. You can apply our patches day or night. The time of application has no bearing on the patch’s effectiveness.

Can I wear more than one patch at a time?

Yes! You can wear one vitamin patch from each of our different single and multivitamin formulations simultaneously. However, do not wear more than one patch per day from the same formulation unless directed by your doctor.

For example, you can wear Vitamin D (Hello Sunshine), Vitamin B12 (Energy Boost), Biotin (Call of Beauty), and Daily Defense all together. However, do not wear more than one patch from the same formulation per day, unless directed by your doctor.
