Question 1
During a galvanic desincrustation treatment, which electrode pole is used and what chemical reaction does it produce on the skin?
Answer: Desincrustation uses the negative pole (cathode), which creates an alkaline chemical reaction that softens and emulsifies sebum and comedones, making them easier to extract during a facial.
Question 2
Which client cannot receive galvanic current treatments?
Answer: Client with a pacemaker
Question 3
What does a Fitzpatrick Type I classification tell an esthetician about a client's skin response to UV exposure?

Question 4
How does LED blue light therapy target acne, and what wavelength range is used during treatment?
Answer: Blue LED light operates at 405–420 nm and kills Propionibacterium acnes (P. acnes) bacteria in the follicle by producing singlet oxygen, making it an effective non-invasive treatment for acne-prone skin.

Question 6
A client presents with visible varicose veins on the legs and requests a full leg wax. What is the appropriate action?

Question 8
A client wants a high-frequency facial to address aging and dry skin. Which method and electrode gas should the esthetician select?

Question 10
What is the difference between melasma and post-inflammatory hyperpigmentation (PIH) in terms of cause and appearance?
