Did you mean Transdermal Permeation?

Glossary Transdermal Permeation

process where substances pass through skin into bloodstream

Transdermal permeation refers to the process by which substances pass through the skin and enter the bloodstream. This method is often used in medical treatments, such as with transdermal patches, to deliver drugs directly into the body without the need for injections or oral medications. The skin's outer layer acts as a barrier, so formulations must be designed to effectively penetrate this layer to achieve therapeutic effects.
