How Do Transdermal
Patches Actually Work?

Transdermal patches deliver active ingredients directly through your skin into the bloodstream — bypassing digestion for faster, more efficient absorption. Here's the science behind why patches are changing wellness.

The Basics

What Is Transdermal Delivery?

A proven method of delivering active ingredients through the skin and directly into the bloodstream — no pills, no digestion, no waste.

Transdermal delivery is the process of absorbing active ingredients through the skin and into the bloodstream. Instead of swallowing a pill and waiting for your digestive system to break it down, a transdermal patch places ingredients directly against your skin where they are gradually absorbed over hours.

Your skin is made of three main layers. The stratum corneum is the outermost barrier — a thin, protective shield. Below that is the epidermis, where ingredients continue their journey inward. Finally, the dermis contains capillaries (tiny blood vessels) that absorb ingredients into your bloodstream.

This route avoids the harsh environment of the stomach and intestines, and completely bypasses first-pass liver metabolism — the process that destroys up to 80% of an oral supplement before it ever reaches your blood.

Step by Step

How Transdermal Patches Deliver Ingredients

From application to absorption — a simple, continuous process that works while you go about your day.

Apply

Place on Skin

Place the patch on a clean, dry area of skin. The adhesive matrix holds active ingredients ready for delivery and keeps the patch secure.

Penetrate

Cross the Skin Barrier

Active ingredients gradually permeate through the stratum corneum — your skin's outermost barrier — using the patch's advanced delivery technology.

Absorb

Enter the Bloodstream

Ingredients pass through the epidermis into the dermis, where capillaries absorb them directly into your bloodstream — no digestion required.

Deliver

Sustained Release

Over 8–12 hours, the patch continuously delivers a steady stream of ingredients. No spikes, no crashes — just consistent, all-day support.

The Advantage

Why Transdermal Beats Oral Supplements

Pills, capsules, and powders all face the same problem: your digestive system destroys most of what you swallow before it can work.

Better Absorption

Oral supplements must survive stomach acid and intestinal enzymes. Transdermal patches bypass the entire GI tract, delivering ingredients directly where they are needed — your bloodstream.

Sustained Release

Pills dissolve all at once, creating a spike-and-crash cycle. Patches provide steady, controlled delivery over 8–12 hours — matching your body's natural rhythm for consistent support.

Higher Bioavailability

When you swallow a supplement, up to 80% can be destroyed by first-pass liver metabolism before reaching your blood. Transdermal delivery avoids this entirely, achieving significantly higher bioavailability.

Our Technology

What Makes Duori Patches Different

Not all patches are created equal. Duori combines advanced adhesive technology, optimized formulations, and rigorous testing.

Advanced Adhesive Matrix

Our medical-grade, hypoallergenic adhesive matrix keeps the patch secure for 8–12 hours while maintaining consistent, controlled ingredient release throughout the day.

Optimized Formulations

Each patch formula is specifically designed for transdermal delivery. We use ingredient forms and molecular weights optimized for skin permeation — not just repackaged pill ingredients.

Quality & Testing

Dermatologist-tested, vegan, non-GMO, and manufactured in facilities following GMP standards. Every batch is tested for consistency, purity, and adhesion performance.

Common Questions

Transdermal Patch Science FAQ

Everything you need to know about how transdermal patches work and why they deliver better results.

Transdermal literally means "through the skin." It refers to delivering active ingredients across the skin barrier directly into the bloodstream, bypassing the digestive system entirely. This method has been used in medicine for decades — from nicotine patches to hormone therapy.
Patches use an adhesive matrix containing active ingredients. When applied to the skin, these ingredients gradually permeate through the stratum corneum (the outermost skin layer), through the epidermis, and into the dermis where capillaries absorb them into the bloodstream. This process happens continuously over 8–12 hours.
Bioavailability is the percentage of an active ingredient that actually reaches your bloodstream in its active form. Oral supplements can lose 50–80% of their potency through digestion and liver metabolism. Transdermal delivery can achieve significantly higher bioavailability because it bypasses these destructive processes entirely.
When you swallow a pill, it must survive stomach acid, digestive enzymes, and first-pass liver metabolism — all of which break down active ingredients before they reach your bloodstream. Patches skip all of these steps by delivering directly through the skin, resulting in more of each ingredient reaching your body in its active form.
Most transdermal patches begin delivering ingredients within 30–60 minutes of application. The delivery then continues steadily for 8–12 hours, providing sustained support rather than a sudden spike followed by a crash.
Transdermal patches have been used in medicine for decades — nicotine patches, pain relief patches, and hormone patches are all well-established examples. Duori's wellness patches are dermatologist-tested, vegan, and made with clean, plant-powered ingredients. As always, consult your healthcare provider if you have specific medical concerns.
Apply patches to clean, dry, hairless skin. Common areas include the inner wrist, upper arm, shoulder, or lower back. Rotate application sites daily to maintain optimal absorption and skin health. Avoid applying to irritated, broken, or recently shaved skin.
Yes. You can wear multiple Duori patches simultaneously on different areas of the body. Many customers combine patches — for example, the Neuro Patch and NAD+ Patch for cognitive support, or the Sleep Patch and Collagen Patch for overnight recovery and skin health.
