California Esthetician Examination with
Practice Questions And Correct Answers
(Verified
1. A client presents with diffuse erythema, telangiectasia, and papulopustular lesions
on the central face. Which treatment modification is MOST defensible for an
esthetician to perform without medical supervision?
A. High-frequency direct application over active pustules to sterilize the lesions.
B. Gentle cleansing, cool compresses, and broad-spectrum SPF with avoidance of heat
and vasodilating modalities.
C. Extraction of all visible comedones followed by a 30% glycolic peel.
D. Microdermabrasion with aluminum oxide crystals at maximum suction to resurface
the affected area.
Answer: B. Gentle cleansing, cool compresses, and broad-spectrum SPF with
avoidance of heat and vasodilating modalities.
Rationale: Rosacea is a vascular-inflammatory condition; estheticians must avoid heat,
vasodilation, aggressive exfoliation, and lesion manipulation. Gentle supportive care with
photoprotection is within scope, while high-frequency on pustules, extraction with strong
acids, and aggressive microdermabrasion risk exacerbation and exceed safe practice.
2. A client requests a chemical peel containing 15% TCA. Which statement reflects the
correct California scope-of-practice and safety judgment?
A. Any TCA concentration may be applied by a licensed esthetician if the client signs a
consent form.
B. TCA peels are outside the esthetician scope; only a physician may perform them, and
the esthetician should refer.
C. Estheticians may apply up to 20% TCA on the face but not the neck.
D. TCA is equivalent to glycolic acid and may be used interchangeably at any
percentage.
Answer: B. TCA peels are outside the esthetician scope; only a physician may perform
them, and the esthetician should refer.
Rationale: Medium-depth peels such as TCA are considered medical procedures in
California and must be performed under physician supervision or by a physician.

,Estheticians may perform superficial peels within defined limits (e.g., low-percentage
AHA/BHA), but TCA at any depth exceeds their scope; consent does not expand legal
scope.

,3. During a facial, a client reports a sudden burning sensation and shows blanching
with a few small blisters on the cheek after application of a product. What is the
esthetician's IMMEDIATE priority?
A. Apply a neutralizing solution and continue the treatment at a lower concentration.
B. Stop the service, remove the product, flush the area with cool water, and assess for
further injury.
C. Apply a thick layer of occlusive ointment and proceed with massage.
D. Document the event and complete the remaining steps of the facial before notifying
the client.
Answer: B. Stop the service, remove the product, flush the area with cool water, and
assess for further injury.
Rationale: The priority is to stop exposure and decontaminate the skin to limit chemical
injury. Continuing the service, applying occlusive products over a potential chemical burn,
or delaying action until after the service all risk worsening tissue damage and violate
standard first-aid and scope-of-practice protocols.
4. Which ingredient pairing in a single facial protocol is MOST likely to produce
excessive barrier disruption and irritant contact dermatitis in a client with sensitive
skin?
A. Hyaluronic acid serum followed by ceramide moisturizer.
B. Niacinamide 5% followed by zinc oxide sunscreen.
C. Salicylic acid 2% cleanser followed by a 10% glycolic acid peel and retinoid serum.
D. Green tea extract toner followed by glycerin-based moisturizer.
Answer: C. Salicylic acid 2% cleanser followed by a 10% glycolic acid peel and
retinoid serum.
Rationale: Layering multiple exfoliating and cell-turnover agents (BHA, AHA, and a
retinoid) in one session substantially increases penetration and barrier insult, especially in
sensitive skin. The other pairings are generally soothing, hydrating, or photoprotective and
do not carry the same cumulative irritation risk.

, 5. An esthetician is evaluating a client's skin under a Wood's lamp. The client's face
shows a blue-white fluorescence in the follicular openings of the nose and chin. What is
the MOST likely interpretation?
A. Dehydration of the stratum corneum.
B. Presence of Propionibacterium acnes colonization.
C. Hyperpigmentation from melasma.
D. Fungal infection of the skin.
Answer: B. Presence of Propionibacterium acnes colonization.
Rationale: Blue-white fluorescence in follicular ostia under Wood's lamp is classically
associated with P. acnes porphyrins. Dehydration typically appears as a dull, ashen tone;
melasma may show accentuation but not blue-white follicular fluorescence; fungal
infections often fluoresce differently (e.g., green or yellow) depending on organism.
6. A client with Fitzpatrick type V skin requests a series of high-frequency facial
treatments and a chemical exfoliation. Which modification is MOST important to
prevent post-inflammatory hyperpigmentation (PIH)?
A. Increase the strength of the exfoliant to ensure visible results in fewer sessions.
B. Avoid all forms of exfoliation and limit treatment to cleansing only.
C. Use lower-strength, non-irritating exfoliants and emphasize rigorous photoprotection
and barrier support.
D. Perform extractions aggressively to clear pores before exfoliation.
Answer: C. Use lower-strength, non-irritating exfoliants and emphasize rigorous
photoprotection and barrier support.
Rationale: Darker Fitzpatrick types have a higher risk of PIH from inflammation or
trauma. Gentle, non-irritating exfoliation combined with strict sun protection and barrier
care minimizes melanocyte stimulation. Aggressive exfoliation or extraction and total
avoidance are both suboptimal; the goal is controlled, safe intervention.
