      Explanation: After extractions, soothe and disinfect the area (tea tree, aloe, masks) to calm irritation. Do not use harsh astringents. Always end with moisturizer and sunscreen.
11. Which question is NOT appropriate to ask during a client consultation?
    • A. “Are you pregnant or nursing?”
    • B. “What medications are you taking?”
    • C. “When was your last facial or waxing service?”
    • D. “How much money do you earn?”
      Answer: D
      Explanation: Personal financial questions are inappropriate. Pregnancy, meds, and recent treatments are relevant to safety. Client confidentiality and comfort are paramount.
12. What do you do if a client has an active cold sore (Herpes labialis) at the time of their scheduled facial?
    • A. Provide the scheduled service as planned
    • B. Apply lip balm and proceed
    • C. Reschedule or skip any treatments around the mouth to avoid spreading the virus
    • D. Use a stronger product to treat the sore
      Answer: C
      Explanation: Active herpes is very contagious. Service should be postponed to prevent virus spread to the esthetician or other areas of the face.
13. When performing a facial, the correct order of steps typically begins with:
    • A. Mask, followed by analysis
    • B. Cleansing, then skin analysis, then treatments (steam, massage, mask, etc.)
    • C. Toner, then exfoliation, then cleanser
    • D. Massage, then cleanser
      Answer: B
      Explanation: Standard facial order: consult, cleanse, analyze under magnification, exfoliate (if needed), steam, extract, massage, mask, tone, moisturize/sunscreen. Proper sequencing ensures effectiveness.
14. Which of the following is a sign a chemical peel is working during a procedure?
    • A. Client feels nothing
    • B. Mild tingling or warmth (if appropriate for the type of peel)
    • C. Immediate flaking of skin within seconds
    • D. Skin turning blue
      Answer: B
      Explanation: Mild tingling or gentle heat is normal for many peels. They should not cause severe burning. Excessive pain or deep redness indicates the peel is too strong or left too long.
15. What should you do at the end of a facial treatment?
    • A. Quickly leave the room to let the client relax alone
    • B. Provide aftercare instructions, recommend products, and have the client fill out post-treatment notes
    • C. Ask them to pay without any explanation
    • D. Take a before photo
      Answer: B
      Explanation: Aftercare (sun protection, product use, follow-up) and retail recommendations are important. It’s also professional to provide the client with treatment notes or a summary of advice.
16. A client with a history of cold sores inquires about lip waxing. You should:
    • A. Wax them while wearing a mask
    • B. Apply numbing cream to prevent pain
    • C. Avoid waxing the lip area during an outbreak and discuss anti-viral precautions (maybe suggest alternative hair removal)
    • D. Wax it anyway; cold sores are not contagious
      Answer: C
      Explanation: Waxing can cause micro-tears that may trigger cold sore activation or spread the virus. If active, waxing is postponed; if not, proceed carefully with hygiene and client’s awareness.
17. What is the main goal of a client treatment plan?
    • A. To sell as many products as possible
    • B. To address the client’s goals and improve their skin health over multiple sessions
    • C. To follow the same routine for everyone
    • D. To finish quickly
      Answer: B
      Explanation: A treatment plan is tailored to client’s needs and sets a roadmap (home care plus professional treatments) to achieve their skincare goals safely and effectively.
18. What detail should be documented after each client appointment?
    • A. Notes on what products were used, procedures performed, and client’s skin response (an “esthetic record”)
    • B. Client’s lunch order
    • C. Weather conditions that day
    • D. How much you enjoyed the service
      Answer: A
      Explanation: Keeping detailed client records (products, settings, skin reactions) is important for continuity of care and legal records. It helps guide future treatments.
19. Which statement about post-treatment care is correct?
    • A. Clients should always wear sunscreen after leaving
    • B. Clients only need sunscreen in the summer
    • C. Sunscreen is not needed if a moisturizer is used
    • D. Sunscreen is only needed on the body, not the face
      Answer: A
      Explanation: Sunscreen is essential every day (especially after exfoliation or peels) to protect sensitive new skin. Always recommend SPF as part of daily regimen.
20. If a client has hyperpigmentation concerns, which facial treatment might you include in the regimen?
    • A. LED light therapy (red)
    • B. High-frequency only
    • C. Enzyme or AHA exfoliant to promote cell turnover (with sun protection advice)
    • D. Paraffin wax mask
      Answer: C
      Explanation: AHAs or enzyme peels help exfoliate pigmented cells and can even tone over time (with strict sun protection). LED red light aids healing but is secondary; paraffin won’t lighten spots.
