Study Notes
Electrical Concepts in Cosmetology
- Nonconductor: An insulator that does not easily transmit electricity.
- Alternating Current (AC): A type of electrical current abbreviated as AC.
- Rectifier: An apparatus that converts alternating current (AC) into direct current (DC).
- Ampere (A, AMP): A unit for measuring the strength of an electric current.
- Milliampere (mA): A smaller unit of measure, equivalent to 1/1,000 of an ampere.
- Ohm (O): A unit used to measure the resistance of an electric current.
- Watt (W): A term to measure how much electric energy is consumed in one second.
Safety Devices
- Fuses and Circuit Breakers: Devices designed to prevent overheating of electrical wires.
Electrotherapy Equipment
- Electrode (aka Probe): An apparatus that conducts electric current from an electrotherapy device to the client's skin.
- Anode (P or +): A positive electrode in electrical circuits.
- Galvanic Current: Common modalities in cosmetology, along with Tesla high-frequency current and Microcurrent.
Applications of Electric Current
- Iontophoresis: The process of introducing water-soluble products into the skin using electric current.
- Cataphoresis: A process that forces acidic substances deeper into tissues using Galvanic current, moving from positive to negative pole.
- Desincrustation: A method that softens and emulsifies grease deposits and blackheads in hair follicles.
- Microcurrent: Extremely low-level electricity that mimics the body's natural electrical impulses.
Light and Energy in Treatments
- Violet Ray (Tesla High-Frequency Current): A therapeutic current known for its high rate of oscillation, used in scalp and facial treatments.
- Steamer: An instrument that produces moist, uniform heat for application to the head or face.
- Wavelength: The distance between two successive peaks of electromagnetic waves.
- Visible Light: Comprises 35 percent of natural sunlight.
- Ultraviolet Rays: Also known as cold light, ultraviolet rays make up about 5 percent of natural light.
- Ultraviolet C (UVC): Light type blocked by the ozone layer.
Additional Treatments
- Infrared Lamps: Primarily used in hair conditioning treatments to enhance the process.
- Laser: Stands for Light Amplification Stimulation Emission of Radiation, used for medical and cosmetic procedures including removing blood vessels and hair follicles.
- LED (Light-Emitting Diode): Used in treatments aimed at reducing acne and increasing skin circulation.
