Transdermal Delivery.
Adhesive-Free.

EPIO INC. has developed a patented adhesive-free nanofiber TDDS platform — delivering active ingredients through the skin with precision, without the skin irritation of conventional patches.

The Problem

Conventional patches have a structural dilemma.

Every adhesive-based patch faces the same trade-off — and no one has solved it. Until now.

⚠️

Skin Irritation

Chemical adhesives cause contact dermatitis, redness, and chronic itching in over 40% of transdermal patch users — the leading cause of early discontinuation.

💧

Low Efficiency

Up to 70% of active ingredients remain trapped in the adhesive matrix, leading to imprecise dosing and significant waste of expensive compounds.

🌀

Poor Breathability

Non-porous structures prevent skin respiration, causing sweat accumulation, maceration, and patch detachment — especially during long-wear applications.

Our Solution

Physical anchoring. Zero adhesive.

Ultra-fine nanofibers (1/1,000 of a hair's width) physically interlock with the skin's micro-contours — no glue required.

Adhesive-Free Bonding

Physical micro-interlocking via nanofiber structure provides secure, non-invasive adhesion — eliminating all adhesive-induced irritation.

Dual-Release Kinetics

Rapid onset (Cmax) + sustained 24H plateau — combining immediate therapeutic effect with long-term dose maintenance in one patch.

Substrate Flexibility

PES membrane base adaptable to alternative polymers. Applicable to both water-soluble and lipid-soluble active ingredients.

Thickness-Based Dosing

Precise active ingredient loading controlled by nanofiber thickness — without increasing patch size or area.
