How does the multi-metal needle composition affect the sensation compared to standard plastic or single-metal applicators?

The Lyapko Duet 6.2 Ag distinguishes itself through its specific multi-metal needle composition, which includes zinc, copper, iron, nickel, and silver. Unlike standard applicators that rely solely on mechanical pressure, this device pairs physical stimulation with a mild skin-level electrochemical interaction. This effect is generated by the contact between these dissimilar metals and the natural moisture on your skin. As a result, the sensation is often described as more complex and deeper than simple pressure alone, providing a stimulus that many users find more even and pronounced. The 6.2 mm needle spacing is considered a moderate option, suitable for adults seeking a strong yet manageable sensation. The needles are set in a flexible rubber base, which ensures consistent contact with the skin's contours, particularly important for narrow areas like the spine or neck. This combination allows for a reflex massage experience that activates surface receptors densely, potentially leading to local muscle relaxation and a warming sensation without the need for powered devices.
