About SEYO TDA (Transdermal Application)

Facial skincare involves a range of activities and products aimed at maintaining, improving, and addressing various skin concerns to keep the skin healthy, hydrated, and looking its best. With DERMADROP´s transdermal application, short TDA, dermatologists and cosmeticians can fulfil this wish. TDA is currently the only non-invasive regenerative therapy that allows maximum deep care of the skin. The active ingredients remain available in the long term thanks to the active ingredient depots formed. For a long time it was only possible to penetrate deeper skin layers using invasive methods.

DERMADROP TDA, on the other hand, works without direct skin contact. All you feel during the treatment is a light, pleasantly cooling massage pressure on the skin surface. The secret of the skin penetration lies in the carrier substance LP3 exclusively developed for DERMADROP and enriched with active substances. During the treatment LP3 is activated with pure oxygen and opens the lamellar structure of the epidermis by approximately 65% and enables the way for active ingredients to deeper skin layers.

For radiantly beautiful skin – from the inside out.

Mechanism: TDA Mode of Action

The TDA carrier, our LP3 complex, is enriched with active substances and mixed with pure oxygen to form micro-units within the TDA applicator.


These micro-units are applied to the skin at high speed in precise synchronisation, where LP3 unlocks the skin barrier creating a gateway for the active agents.


The active ingredients such as deep-acting hyaluronic acid can penetrate the deepest skin layers.


After just a few treatments, deposits are created that foster cell division and skin regeneration in the long term.

Before and After Effect

After just a few TDA applications, depots are created and the skin is perfectly restarted. Whether a visible freshness boost immediately after the treatment or a long-term improvement in skin appearance – the results are convincing customers worldwide and provide smiling faces. It is recommended to start with a cure with 1-2 treatments a week to reset the undernourished skin from scratch. Then switch to 1 treatment for a total cure of 6 weeks. Subsequently, an interval of 4 – 6 weeks between treatments is recommended.
