Effects of Electric Current
The 3 types of electrically powered equipment typically used in the salon are:
Thermal
Mechanical
Combination
______ is the use of a specific current or equipment for corrective and therapeutic benefits on the skin.
Electrotherapy
Alternating current is interrupted to produce a mechanical, non-chemical reaction.
EMS, ELECTRIC Muscle STIMULATION (FARADIC CURRENT)
The production of beneficial effects such as reducing acne through treatments using light rays or waves are:
Light Therapy
The application of special currents that have a variety of effects on the skin is called:
electrotherapy
The effects of electric current has three kinds of effects, what are they?
Heating effects, Mechanical or magnetic effects, Electrochemical effects
What are the benefits of electrotherapy include?
Benefits include:
Skin firming
Deep firming
Deep cleansing
Germicidal cleansing
Hydration
Deeper product penetration
EMS benefits include what?
Improved blood circulation
Improved muscle tone
Stimulation of hair growth
Increased glandular activity
Light-emitting diode (LED) devices are primarily used to:
Reduce acne (blue light)
Increase circulation (red light)
Reduce Inflammation (yellow light)
Reduce hyperpigmentation (green light)
Which of the following currents has chemical effects that are caused by passing the currents through particular acid or alkali solutions, then through body tissues and fluids?
galvanic
Explain what heating effects.
The flow of current causes special conductors to produce heat.
What are the electrotherapy currents?
Galvanic, EMS, Microcurrent, High-Frequency (Tesla)
The most frequently used application of EMS is the indirect method of electrotherapy. The indirect methods are:
The salon professional usually wears a wristband with a moistened electrode.
The second electrode is wrapped in moist cotton and either held by the client or, better, attached to the client’s lower neck between the shoulders.
The salon professional’s fingers are then placed on the client’s face before the current is turned on to prevent shock.
When the current reaches the desired level, a facial massage is given, with a particular focus on motor points.
The current is gradually decreased and finally turned off completely before the salon professional’s fingers are removed.
Intense pulse light (IPL) devices are used to treat:
Spider veins
Wrinkles
Hyperpigmentation
Excessive hair
Rosacea
What temporary effect will a negative pole produce when applying galvanic current during an electrotherapy treatment?
increase in blood flow
Explain the mechanical or magnetic effects.
The push-pull effect causes the motor to turn.
What is the current conductor used to bring the current from the appliance to the client’s skin?
Electrode
What is the direct method of application used less often for EMS, places both electrodes on the client’s skin, making certain that the electrodes never touch.
The current is turned on and slowly increases only after the electrodes are in place.
In this application, the current travels through the motor nerves between the two electrodes, causing muscle stimulation.
The portion of the electromagnetic spectrum humans can see through____________.
Visible Light
If a cream is used during scalp or other high-frequency treatments, be sure the cream contains no:
alcohol
What are the electrochemical effects?
Electric current travels through a water-based solution.
The existence of a certain condition that suggests it is inadvisable to perform a procedure.
Pregnancy
Heart condition and/or a pacemaker
Epilepsy
High blood pressure
Open cuts, abrasions, or sores
Diabetes
Dilated (couperose) capillaries
Metal plates, pins in the body, or dental braces
What are the three Methods for Using High-Frequency?
Direct Application, Indirect Application, and General Electrification
The ______ combination light is broken into individual wavelengths by a prism.
White Light
Which of the following is a benefit of using infrared light during a facial?
increases circulation
