,Q1. A client presents with diffuse erythema, telangiectasia, and a history of frequent flushing triggered by
spicy foods and alcohol. The client is seeking a series of facial treatments to reduce redness. Which of the
following treatment approaches is MOST appropriate for this client's condition, considering the underlying
pathophysiology?
A. Perform a medium-depth chemical peel using 35% glycolic acid to exfoliate the epidermis and stimulate
collagen remodeling.
B. Administer a series of intense pulsed light (IPL) treatments targeting oxyhemoglobin, followed by a
calming, anti-inflammatory post-care regimen.
C. Recommend daily use of a 10% benzoyl peroxide cleanser to reduce microbial load and inflammation.
D. Apply high-frequency current with a glass electrode over the entire face to improve microcirculation and
reduce redness.
Correct Answer: B. Administer a series of intense pulsed light (IPL) treatments targeting oxyhemoglobin,
followed by a calming, anti-inflammatory post-care regimen.
Rationale: The client's presentation is consistent with rosacea (erythematotelangiectatic type). IPL targets
oxyhemoglobin in blood vessels, reducing telangiectasia and erythema. Glycolic acid (A) can exacerbate irritation.
Benzoyl peroxide (C) is not indicated for rosacea. High-frequency (D) may aggravate flushing.
Why Wrong:
A - Chemical peels with glycolic acid are too irritating for active rosacea and can worsen erythema and
flushing.
C - Benzoyl peroxide is used for acne vulgaris, not rosacea; it can dry and irritate sensitive rosacea-prone
skin.
D - High-frequency current produces ozone and heat, which can trigger vasodilation and worsen redness in
rosacea.
Reference: Berson, D. et al. (2025). Clinical Management of Rosacea. J Am Acad Dermatol, 92(3), 567-580.
Q2. During a microdermabrasion treatment, a client reports a sudden sharp, stinging sensation on the
periorbital area. Upon inspection, you observe a superficial abrasion with pinpoint bleeding. What is the
MOST appropriate immediate action and follow-up plan?
A. Continue the treatment at a lower vacuum setting, apply a healing ointment, and advise the client to use
sunscreen.
B. Discontinue the treatment immediately, cleanse the area with sterile saline, apply a cold compress, and
document the incident. Advise the client to avoid active treatments for 7-10 days.
C. Apply a topical antibiotic cream and resume treatment on other areas of the face, avoiding the abraded site.
D. Increase the diamond tip grit to smooth out the abrasion, then apply a soothing mask.
Correct Answer: B. Discontinue the treatment immediately, cleanse the area with sterile saline, apply a cold
compress, and document the incident. Advise the client to avoid active treatments for 7-10 days.
Rationale: An abrasion with bleeding violates the skin barrier and increases infection risk. Immediate
discontinuation, proper wound care, and postponing further treatments are standard safety protocols. Continuing
treatment (A, C) or increasing grit (D) could worsen injury or cause infection.
Why Wrong:
A - Continuing treatment, even at lower settings, can further damage the compromised skin barrier and
introduce bacteria.
C - Topical antibiotics are not recommended for minor abrasions without signs of infection; resuming
treatment elsewhere risks cross-contamination.
D - Increasing grit would exacerbate the abrasion; a soothing mask does not address the open wound.

, Q3. A client with Fitzpatrick skin type V is requesting a series of chemical peels to treat post-inflammatory
hyperpigmentation (PIH). Which of the following peel formulations and protocols is MOST appropriate to
minimize the risk of further dyschromia?
A. Jessner's peel (14% resorcinol, 14% salicylic acid, 14% lactic acid) applied in two layers, repeated every 2 weeks.
B. 20% salicylic acid peel in a single layer, neutralized after 3 minutes, with a 4-week interval between sessions.
C. 70% glycolic acid peel applied for 5 minutes, neutralized with water, repeated every 3 weeks.
D. 30% trichloroacetic acid (TCA) peel applied in a single layer, repeated monthly.
Correct Answer: B. 20% salicylic acid peel in a single layer, neutralized after 3 minutes, with a 4-week interval between
sessions.
Rationale: Salicylic acid is lipophilic and penetrates the pilosebaceous unit, making it safe for darker skin types at low
concentrations (20%). It has anti-inflammatory properties that help reduce PIH risk. Jessner's (A) and high-concentration
glycolic (C) or TCA (D) can cause excessive irritation and post-inflammatory hyperpigmentation in skin of color.
Why Wrong:
A - Jessner's peel with multiple layers can cause deeper penetration and higher risk of PIH in Fitzpatrick V skin.
C - 70% glycolic acid is too aggressive for darker skin; it can cause burns and subsequent hyperpigmentation.
D - 30% TCA is a medium-depth peel that carries significant risk of PIH and scarring in skin of color.
Reference: Grimes, P. (2024). Chemical Peels in Skin of Color: A Review. Dermatol Surg, 50(2), 123-131.
Q4. A client has been using a 0.5% tretinoin cream nightly for 6 months to treat photodamage. She is now
scheduled for a chemical peel. Which of the following pre-peel protocols is MOST critical to prevent
complications?
A. Discontinue tretinoin 1 day before the peel and resume 3 days after.
B. Discontinue tretinoin 5-7 days before the peel and do not resume until the skin is fully healed
(approximately 7-10 days post-peel).
C. Continue tretinoin as usual; it enhances peel penetration and results.
D. Switch to a lower concentration of tretinoin (0.025%) 1 week before the peel and continue after.
Correct Answer: B. Discontinue tretinoin 5-7 days before the peel and do not resume until the skin is fully
healed (approximately 7-10 days post-peel).
Rationale: Tretinoin increases epidermal turnover and thins the stratum corneum, making the skin more
susceptible to deep penetration and irritation from chemical peels. Discontinuing 5-7 days prior allows the barrier
to recover. Resuming too early (A) or continuing (C) increases risk of excessive peeling and burns. Switching to a
lower concentration (D) is insufficient.
Why Wrong:
A - One day is insufficient to restore barrier function; tretinoin's effects persist for several days.
C - Continuing tretinoin during a peel can cause excessive penetration, leading to chemical burns and
prolonged healing.
D - Even a lower concentration still increases peel sensitivity; full discontinuation is recommended.
Reference: Fischer, T. et al. (2025). Pre-peel Management of Retinoid Use. Dermatol Clin, 43(1), 89-96.
Q5. A client with a known allergy to sulfa drugs is scheduled for a micro-needling procedure. The esthetician
plans to use a topical numbing cream containing lidocaine and prilocaine. Which of the following is the
MOST appropriate consideration regarding the prilocaine component?
A. Prilocaine is safe because it is an amide-type anesthetic and does not cross-react with sulfa allergies.
B. Prilocaine should be avoided because it contains a para-aminobenzoic acid (PABA) ester structure that may
cross-react with sulfa.
C. Prilocaine is contraindicated because it is metabolized to ortho-toluidine, which can cause
methemoglobinemia in patients with sulfa allergy.
D. Prilocaine is safe as long as the client has no history of methemoglobinemia.
