Inconsistent manual application of cosmetic or medical treatments leads to suboptimal results or safety risks. Precise sensing and frequency control ensure therapeutic efficacy regardless of user technique.

Physical isolation of internal circuitry prevents traditional manual input for configuration or recovery. Overcoming this limitation allows for environmental sealing without sacrificing user control over device connectivity.

Active ingredients and oils in cosmetic sticks and cleansers often suffer from phase separation or poor structural integrity. Ensuring stable viscosity and adhesion prevents product failure during application.
