Esthetician Practice Advanced Facial Treatments Questions and Answers — Questions and Answers
Question 1: A client with active, inflamed acne is seeking a treatment to help kill bacteria and reduce inflammation. Which combination of LED light therapy would be MOST effective?
- Blue and red light (Correct answer)
- Green and yellow light
- Red and infrared light
- Blue and green light
Correct answer: Blue and red light
Blue light therapy is effective at killing acne-causing bacteria (C. acnes) on the skin's surface, while red light therapy penetrates deeper to reduce inflammation and promote healing. This combination addresses both the cause and the symptoms of inflammatory acne.
Question 2: An esthetician is performing an ultrasonic facial using a skin scrubber. To ensure proper function and effective exfoliation, what is the correct way to hold the device and what must be present on the skin?
- At a 90-degree angle on dry skin
- Flat against the skin with a thick oil
- At a 45-degree angle on wet skin (Correct answer)
- At a 25-degree angle with a clay mask
Correct answer: At a 45-degree angle on wet skin
For an ultrasonic skin scrubber to work correctly for exfoliation (desincrustation), the skin must be kept wet. The device is held at approximately a 45-degree angle to the skin, allowing the ultrasonic vibrations to pulverize the water and gently push out impurities from the pores.
Question 3: A client who is a Fitzpatrick Type V is interested in a chemical peel to address hyperpigmentation. Which of the following is the most important consideration for the esthetician?
- This skin type cannot receive chemical peels.
- A deep peel, such as a phenol peel, is most effective.
- There is a higher risk of post-inflammatory hyperpigmentation. (Correct answer)
- Pre-treatment with hydroquinone is always required.
Correct answer: There is a higher risk of post-inflammatory hyperpigmentation.
Higher Fitzpatrick types (IV-VI) have more melanin and a more active response to inflammation, which puts them at a greater risk of developing post-inflammatory hyperpigmentation (PIH) after treatments like chemical peels. Estheticians must proceed with caution, often using lighter peels and proper pre- and post-care to minimize this risk.
Question 4: Which of the following is a primary contraindication for a microcurrent facial treatment?
- Dehydrated skin
- Presence of fine lines and wrinkles
- History of seasonal allergies
- A client with a pacemaker (Correct answer)
Correct answer: A client with a pacemaker
Microcurrent technology uses low-level electrical currents to stimulate facial muscles. For this reason, it is contraindicated for individuals with pacemakers, epilepsy, or other electrical implants, as the current could interfere with the device's function.
Question 5: During a high-frequency treatment, the esthetician uses a glass electrode that produces a violet-colored light. This type of electrode is typically used for what skin type and concern?
- Mature, aging skin
- Sensitive, couperose skin
- Oily, acne-prone skin (Correct answer)
- Dry, dehydrated skin
Correct answer: Oily, acne-prone skin
The violet high-frequency electrode is filled with Argon gas and is used for treating oily and acne-prone skin. The current creates ozone gas at the skin's surface, which has a germicidal, antibacterial effect that helps to kill acne-causing bacteria and heal blemishes.
Question 6: A client receives a series of microdermabrasion treatments. The primary goal of this procedure is to exfoliate and remove dead cells from which layer of the skin?
- Stratum spinosum
- Stratum corneum (Correct answer)
- Papillary dermis
- Reticular dermis
Correct answer: Stratum corneum
Microdermabrasion is a form of mechanical exfoliation that targets the stratum corneum, the outermost layer of the epidermis. Removing the excess accumulation of these dead skin cells helps to improve skin texture, reduce the appearance of fine lines, and allow for better product penetration.
