Direct high-frequency application causes which of the following effects?

Explanation:
Direct high-frequency application mainly warms the skin's tissues. The high-frequency current passes through the skin and its resistance converts part of that electrical energy into heat, producing a local thermal effect. This heating leads to vasodilation and increased local blood flow, which can help with tissue warming, soften skin, and improve product absorption. It does not reduce circulation, decrease metabolism, or dull nerve responses—the heating effect actually promotes blood flow and can heighten metabolic activity in the treated area, not diminish it.
