Non-Transdermal

« Back to Glossary Index

Non-transdermal refers to a product design or delivery mechanism where no chemicals, drugs, or active ingredients pass through the skin barrier or enter the bloodstream. Within the framework of wellness patches, this means the active elements are completely sealed within the device, relying entirely on surface interactions like phototherapy to stimulate the body rather than chemical absorption.

For a technical breakdown of how topical absorption vs. surface barrier systems function in consumer products, you can view the foundational scientific entry on Wikipedia.
