CIDESCO PRACTICAL EXAM
QUESTIONS AND ANSWERS GRADED A+
2025/2026
What is an enzyme? - ANS A biological catalyst that speeds up chemical reactions; the
chemical reaction we want is the break-down of keratin
How long do you leave on an enzyme? - ANS 15 minutes [it takes that long for the chemical
reaction to occur]
Why don't you use ozone on the steamer with an enzyme on the skin? - ANS Ozone would
deactivate the enzyme
What type of currant is Galvanic Iontophoresis? - ANS A constant direct current
What does Iontophoresis current do to the skin? - ANS It forces electrically charged particles
deeper into the skin
What type of product do you use to force the product into the skin for Iontophoresis? -
ANS It needs to be water based to conduct electricity
Iontophoresis- what polarity do you use to force the product into the skin? - ANS Negative
electrode on the face first to penetrate negatively charged ingredients; then I'll change polarity
to positive to penetrate the positively charged ingredients

, Why do you apply the negative electrode first in Iontophoresis? - ANS Because the negative
electrode also creates an alkalinity on the skin. With the positive electrode I not only penetrate
positive particles but put the skin back to its slightly acidic pH
How does the client benefit from Iontophoresis? - ANS The ingredients will arrive deeper in
the skin where cells can metabolize the. Additionally, moisture will enter the skin through
electro-osmosis. The skin will be moist and plump and the conditions will be addressed at their
source.
What are contraindications for Iontophoresis? - ANS Epilepsy
Metal plates and pins
Pacemaker/defibrillator
Heart insufficiencies
Pregnancy
Infections
Fever
Cancer
Open wounds and sores
Loss of neural sensitivity
What are safety precautions for Iontophoresis? - ANS No metal parts of the electrodes may
touch the skin
There needs to be plenty of moisture at both electrodes
Electrodes need to be evenly covered with cotton or tissue, or have a banana-peel thick layer of
gel on the face to prevent a chemical burn
I make sure the intensity is down at 0 before I turn on the machine. I increase intensity slowly
until my client feels a slight tingle or gets a metal taste. Never increase higher than 2.0
milliamperes.
I keep contact with the skin at all times as long as current is flowing.
I turn down my intensity and turn off the machine before I remove the electrode from my
client's skin.
