Free Esthetician Practice Facial Treatments and Devices Questions and Answers — Questions and Answers
Question 1: An esthetician is performing a galvanic current treatment to facilitate extractions on a client with oily, congested skin. Which process are they using, and what chemical reaction does it create?
- Cataphoresis, which causes an acidic reaction to harden sebum.
- Iontophoresis, which introduces water-soluble products into the skin.
- Desincrustation, which creates a chemical reaction called saponification. (Correct answer)
- High frequency, which produces ozone to create a germicidal effect.
Correct answer: Desincrustation, which creates a chemical reaction called saponification.
Desincrustation is the process that uses the negative pole (anaphoresis) of a galvanic current to soften and emulsify sebum and debris in the follicles. This process creates a chemical reaction known as saponification, which turns the sebum into soap, making extractions much easier.
Question 2: A client with mild to moderate acne wants a non-invasive treatment to help manage their breakouts. Which of the following devices and mechanisms of action would be most appropriate and effective for targeting acne-causing bacteria?
- Microcurrent, which uses low-level electricity to stimulate facial muscles.
- Red light LED, which penetrates deeply to stimulate collagen and reduce inflammation.
- Ultrasonic spatula, which uses sound waves for mechanical exfoliation.
- Blue light LED, which destroys P. acnes bacteria on the skin's surface. (Correct answer)
Correct answer: Blue light LED, which destroys P. acnes bacteria on the skin's surface.
Blue light LED therapy, typically in the 405-420 nanometer range, is highly effective for treating mild to moderate acne. It works by penetrating the epidermis to kill Propionibacterium acnes (P. acnes), the bacteria responsible for many acne breakouts, without harming the surrounding tissue.
Question 3: During a facial treatment, an esthetician uses an ultrasonic skin scrubber (spatula). What is the primary principle behind how this device exfoliates the skin?
- It uses a direct electrical current to dissolve sebum in the pores.
- It emits thermal energy to melt away the stratum corneum.
- It uses high-frequency sound waves to create vibrations that loosen dead skin cells. (Correct answer)
- It projects fine crystals onto the skin to abrade the surface.
Correct answer: It uses high-frequency sound waves to create vibrations that loosen dead skin cells.
An ultrasonic skin scrubber, or spatula, works through a process called cavitation. It uses high-frequency sound waves (typically 28,000 to 30,000 vibrations per second) that, when applied to wet skin, create vibrations that loosen and 'jiggle' out dead skin cells, oil, and debris from the pores for effective exfoliation.
Question 4: A new client is booked for a microdermabrasion treatment. During the consultation, they mention they have been using a prescribed oral medication for severe acne for the past three months. Which is the MOST appropriate course of action for the esthetician?
- Perform the treatment but use the lowest possible suction setting.
- Proceed with the treatment as it will help with acne scarring.
- Advise the client to stop the medication for 48 hours before the treatment.
- Refuse the service and explain that the medication is a contraindication. (Correct answer)
Correct answer: Refuse the service and explain that the medication is a contraindication.
Oral medications for severe acne, such as isotretinoin (commonly known as Accutane), are a major contraindication for aggressive exfoliation treatments like microdermabrasion. These medications thin the skin and make it extremely sensitive, increasing the risk of severe irritation, scarring, and delayed healing. It is recommended to wait at least 6 months after discontinuing the medication before performing microdermabrasion.
Question 5: Which of the following is a significant contraindication for any facial treatment involving electrical currents, such as microcurrent, galvanic, or high frequency?
- The client has seasonal allergies.
- The client has a pacemaker or heart condition. (Correct answer)
- The client has mild hyperpigmentation.
- The client has previously had Botox injections.
Correct answer: The client has a pacemaker or heart condition.
The use of electrical currents is contraindicated for individuals with pacemakers, heart conditions, or other implanted electronic devices. The electrical current from the facial device can potentially interfere with the functioning of the medical implant, posing a serious health risk. Other major contraindications include epilepsy, pregnancy, and metal implants in the treatment area.
Question 6: An esthetician is using a high-frequency machine on a client with acneic skin. They select the mushroom-shaped electrode. What is the primary purpose of this specific electrode?
- To perform extractions by creating suction.
- For spot-treating individual small pimples.
- For treating larger surface areas like the cheeks and forehead. (Correct answer)
- To infuse serums deep into the epidermis.
Correct answer: For treating larger surface areas like the cheeks and forehead.
The mushroom-shaped electrode for a high-frequency machine is designed to treat larger, broader areas of the face, such as the cheeks, forehead, and jawline. Its shape allows for maximum skin contact to diffuse the germicidal and healing effects of the current over a wider surface area.
