Why Electroporation Works Better with Nanoparticles than Microneedling, Ultrasound or Galvanic Ironing

These molecules may carry high biological potential. The key question remains the same: how to deliver them through the skin barrier.

The stratum corneum is an exceptionally effective protective system. It consists of keratinocyte layers connected by a lipid matrix that mainly allows small, lipophilic molecules to pass. Most modern actives are larger, hydrophilic or encapsulated in carriers. This is why professional cosmetology relies on different transdermal delivery methods.

Microneedling: a mechanical pathway

Microneedling is based on mechanical disruption of the skin. Micro-needles create tiny channels in the epidermis through which actives can penetrate deeper.

• hyaluronic acid
• selected peptides
• vitamins
• regenerative serums

The limitation is that transport is not controlled. Delivery happens mainly by diffusion and distribution may be uneven.

Ultrasound: energy in motion

Ultrasound uses mechanical vibration and a phenomenon called cavitation, which temporarily disrupts the lipid structure of the stratum corneum. This can increase skin permeability, especially for smaller molecules, hydrophilic substances and some delivery systems. Its effect on larger structures, such as nanovesicles, is limited.

Galvanic ironing: ionic delivery

Galvanic technology uses electrical current to deliver ionised substances through iontophoresis. The current repels ions of the same charge and pushes them into the skin. The method is effective mainly for small ionised molecules, selected vitamins and minerals. Large structures such as liposomes or nanoparticles are transported with difficulty.

Electroporation: controlled transport

Electroporation uses short electrical pulses to create temporary hydrophilic microchannels in the lipid membrane of the stratum corneum. These channels exist only briefly, yet they can significantly increase skin permeability.

• peptides
• biomimetic molecules
• liposomes
• nanoparticles
• plant extracellular vesicles

Transport is not purely passive. The electric field can influence the movement of charged molecules and facilitate their penetration into epidermal layers.

Why electroporation matters in modern cosmetology

New generations of cosmetic ingredients are increasingly sophisticated and often work with cellular communication, regeneration and antioxidant protection. Plant nanovesicles are a typical example: they carry bioactive molecules in natural phospholipid structures. These systems are usually around 50-200 nm in size, which makes penetration through an intact barrier very limited. This is where electroporation may play an important role.

The future of transdermal cosmetology

Cosmetology is rapidly moving toward biotechnological ingredients. Alongside peptides and ferments, biomimetic vesicles and other advanced delivery systems are emerging. As a result, methods that can truly deliver these substances into the skin are becoming more important. Electroporation is among the technologies enabling controlled and efficient delivery without mechanical skin injury, which is why it is increasingly integrated into modern professional treatments.
