What does “different metals in the needles” mean, and why is it done? — Applicator 36mm x 84mm-Lyapko

In Lyapko applicators the needles are made from alloys of different metals. This is not simply a design choice: it is believed that when dissimilar metals come into contact with moist skin, weak micro-galvanic currents arise — a phenomenon known from physics as a galvanic couple.

This effect is regarded as an addition to the main mechanical action of the needles. Mechanical irritation on its own increases local blood flow, creates a feeling of warmth and helps muscles relax. The micro-galvanic component, by design, adds to these processes at the level of skin receptors.

It is important to understand that the Lyapko applicator is not a medical device or a medicine. Its action is reflex and mechanical in nature. Claims about micro-galvanics reflect the brand’s concept, not a clinically proven therapeutic mechanism. If you are interested in a therapeutic effect for a specific condition, it is better to discuss this with a doctor.

For everyday use — relieving stiffness, relaxing after a working day, shifting attention away from tension — the difference in metal composition hardly requires any special knowledge from the user. It is enough to ensure clean contact of the needles with the skin and to observe the recommended contact time.
