EPN - Needling Pen with electroporation
The EPN Needling Pen (Electroporation Needle) is a professional microneedling device that combines the benefits of dermal needling with the advanced technology of electroporation.
The EPN Needling Pen is an EU-approved Class 2 medical device that increases the absorption of active ingredients by combining microneedling and electroporation. Electroporation makes cell membranes more permeable, allowing active ingredients to better penetrate the tissue.

Device for professional users
Microneedling and electroporation in one handpiece
The EPN Needling Pen combines motorised microneedling with electroporation. Needle depth (0.0 to 2.0 mm), motor speed (three levels) and electroporation (five levels) can be adjusted separately. It uses sterile single-use heads with 9 electrode needles in 33G.

- Needle depthcontinuously adjustable from 0.0 to 2.0 mm
- Motor / electroporation3 motor levels / 5 electroporation levels
Medical device. Use by qualified professionals in accordance with the instructions for use.Needle heads are sterile single-use items and are not included.
Two technologies, one device
The EPN system combines automatic microneedling with electroporation. The information below is based on the operator manual and manufacturer documentation.

Automatic microneedling (Auto MTS)
- vertical stamping with motorised drive
- continuously adjustable needle depth from 0.0 to 2.0 mm
- 9 electrode needles per sterile single-use head, 33G
- three speed levels: 4,000, 4,500 and 5,000

Electroporation
- electrical pulses designed to temporarily increase membrane permeability
- five intensity levels
- combined with the needling system in the same device
This page deliberately does not state a numerical increase in active-ingredient uptake. The manufacturer brochure refers to preclinical data and literature for this point.
Manufacturer diagrams, schematic. Intended purpose, instructions for use and professional assessment remain decisive.
Parameters from the manufacturer protocol
The supplied protocol specifies depths for the face and scalp. Select an entry; the diagram shows the stated needle depth schematically.
Schematic cross-section, not to scale. The manufacturer protocol states 1.0 mm for scalp needling alone and 0.5 mm for needling + EP; for the face, 1.0 mm at the cheek/nasolabial line and 0.5 mm in other areas. Treatment protocol.
