Question 1

What does a Fitzpatrick Type I classification tell an esthetician about a client's skin response to UV exposure?

Accepted Answer

Fitzpatrick Type I describes very fair skin with freckles that always burns and never tans, requiring SPF 50+ protection and heightened caution with any heat-based or light-based treatments.

Question 2

During a galvanic desincrustation treatment, which electrode pole is used and what chemical reaction does it produce on the skin?

Accepted 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 3

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

Accepted Answer

The indirect method is used for aging and dry skin, where the client holds the electrode and the esthetician massages the face to generate warmth; orange neon gas electrodes are appropriate for this concern.

Question 4

What is the maximum depth of penetration for a superficial chemical peel, and which acid categories are considered within an esthetician's scope of practice?

Accepted Answer

Superficial peels penetrate the epidermis only, from the stratum corneum to the stratum granulosum; AHAs such as glycolic and lactic acid and the BHA salicylic acid are within esthetician scope in most states.

Question 5

Why is a deep chemical peel using phenol or TCA 50%+ outside the scope of practice for an esthetician?

Accepted Answer

Deep peels penetrate the reticular dermis, posing risks of scarring, systemic absorption, and cardiac toxicity; they require physician supervision and are never within an esthetician's legal scope of practice.
