Esthetics Facial Devices

How long should you leave the electric mitts on the client's hands?

• 5 minuites

• 10 minutes

• 15 minutes

• 20 minutes

During desincrustation, before you turn on galvanic current,

you should make sure the electrode is____

• away from the client's skin

• directly on the client's skin

• covered with a moist sponge

• held in the client's hand

When using a Wood's lamp, dehydrated skin will appear_____

• as a clump of white spots

• light violet

• brown

• yellow or pink

What is the best explanation for iontophoresis?

• introduces water-soluble products without ions into the skin

• introduces insoluble products with ions into the skin

• introduces insoluble products without ions into the skin

• introduces water-soluble products with ions into the skin

How does a high frequency facial machine work?

• It uses ultraviolet light to remove bacteria from the skin

• It exfoliates the skin using a combination of chemicals

• It applies a cooling gel to reduce inflammation and redness

• It produces a mild electrical current that generates heat and oxygen to kill bacteria and promote circulation.

What are the two types of electrodes used in high frequency facial machines?

• Flat electrode and star electrode

• Round electrode and hexagon electrode

• Mushroom electrode and spoon electrode

• Square electrode and triangle electrode

Explain the process of desincrustation in galvanic facial machines.

• The process of desincrustation involves the use of a positive electrode

• Desincrustation in galvanic facial machines does not involve any chemical reaction

• The process of desincrustation in galvanic facial machines uses a neutral electrode

• The process of desincrustation in galvanic facial machines involves the use of a negative electrode to create a chemical reaction that helps to soften and dislodge impurities from the skin.

The two significant reactions caused by galvanic current are:

• chemical and machanical

• ionic and manual

• chemical and ionic

• desincrustation and iontophoresis

The electric device that cleans the skin

and has a healing effect on the skin is

• ultrasound

• laser

• galvanic

• high-frequency

Galvanic current is used during desincrustation

to create a chemical reaction that_______

• liquefies the top of the stratum corneum

• disinfects acne pustules

• solidifies sebum

• emulsifies sebum
