Promotes oxygenation and has an antiseptic effect
Increases the depth of product penetration through iontophoresis
Cooling the skin surface
ExplanationHigh-frequency currents produce ozone, which is highly oxygenating and provides an antiseptic benefit, often used to treat acne.
Increased atmospheric pressure
Heat-induced vasodilation and increased perspiration
Magnetic attraction of pollutants
Refractive index changes
ExplanationSteam warms the skin, causing blood vessels to dilate (vasodilation) and increasing sweat production, which helps soften debris in the pores.
Ohm's Law
Newton's First Law
The Law of Thermodynamics
