How does the metal composition differ from standard plastic massage mats?

Standard massage mats typically rely solely on mechanical pressure from plastic or rubber spikes. In contrast, this Lyapko applicator uses a system of metal needles set in medical-grade rubber. The needles are coated with copper, nickel, and zinc. The "Ag" designation in the product name refers to silver, a feature associated with this specific line. Beyond simple mechanical contact, the metal composition allows for a mild galvanic interaction with the natural moisture on your skin. This interaction is a key reason why users often report that these applicators feel different from simple plastic alternatives, potentially enhancing the sensation of local microcirculation and making the area feel more awake and responsive.
