Is Cold Plasma The Same As High Frequency? Key Differences

July 20, 2025

Is cold plasma the same as high frequency?No, cold plasma and high frequency are distinct technologies that work through different mechanisms^[7]. While both treatments target acne and skin rejuvenation, cold plasma generates ionized gas at room temperature, whereas high frequency uses electrical currents through glass electrodes filled with inert gas^[5]. Understanding these fundamental differences helps patients choose the most appropriate treatment for their specific skincare needs.

Many people confuse these technologies because some marketing materials incorrectly label high frequency devices as “cold plasma.” However, the scientific mechanisms, treatment outcomes, and clinical applications differ significantly between these two approaches.
