NIC Esthetician Written ExamTreatment ProceduresMedium
A client with Fitzpatrick skin type I presents for a facial and expresses concerns about hyperpigmentation and fine lines. The esthetician recommends a superficial chemical peel. Which of the following acids is MOST appropriate for this client's skin type and concerns?
- ATrichloroacetic acid (TCA)
- BJessner's solution
- CGlycolic acid
- DSalicylic acid
Show answer & explanationAnswer & explanation
Correct answer: C. Glycolic acid
Glycolic acid, an alpha hydroxy acid (AHA), is a superficial peel agent suitable for Fitzpatrick skin type I, effectively addressing hyperpigmentation and fine lines without significant risk of post-inflammatory hyperpigmentation. TCA and Jessner's solution are medium-depth peels that carry higher risks for this skin type, while salicylic acid is primarily for acne-prone skin.
Why the other options are wrong
- A. TCA is a medium-depth peel, which can be too aggressive for Fitzpatrick I without careful consideration and carries higher risks.
- B. Jessner's solution is a medium-depth peel that is more potent and carries higher risks of irritation and PIH for lighter skin types if not properly managed.
- D. Salicylic acid is a beta hydroxy acid (BHA) primarily used for acne and oily skin, not the primary choice for hyperpigmentation and fine lines in dry/normal skin.
Superficial Chemical Peels
Chemical peels that only affect the epidermis, used for mild skin concerns like fine lines, uneven tone, and light hyperpigmentation.
- Uses alpha hydroxy acids (AHAs) like glycolic or lactic acid.
- Suitable for all Fitzpatrick skin types, especially lighter types.
- Requires minimal downtime and has a low risk of complications.
