In a clinical setting, the "40" concentration is often used for "The Perfector" or similar nano-current resurfacing treatments. When applied in conjunction with electrical currents (microcurrent or nanocurrent), the high ion concentration of the serum acts as a conductor. This allows the active ingredients to be driven deeper into the dermis than topical application alone could ever achieve.
The EssentialFX 40 was built with accuracy in mind. Unlike standard models that can suffer from lag or "drift," the 40-series architecture ensures that every input is met with an immediate, precise output. This is crucial for high-stakes environments where there is no room for error. essentialfx 40
