NIC Esthetician Written ExamScientific ConceptsHard
A client is experiencing persistent discomfort, including itching, stinging, and burning, after using a new skincare product. Upon examination, the esthetician observes redness, swelling, and small vesicles (blisters) on the affected areas. The client reports no prior history of allergies to cosmetics. This reaction is indicative of an immune response directly to a topical substance, rather than an internal systemic issue.

Show answer & explanationAnswer & explanation
Correct answer: A. Contact Dermatitis
Contact dermatitis is an inflammatory skin condition caused by direct contact with an irritating or allergenic substance. Symptoms include redness, itching, swelling, and sometimes vesicles or blisters, precisely matching the client's presentation after using a new product.
Why the other options are wrong
- B. Urticaria (hives) presents as raised, itchy welts that appear and fade quickly.
- C. Psoriasis involves thick, silvery-scaled plaques, not typically acute blistering from a product.
- D. Rosacea presents with chronic facial redness, telangiectasias, and papules/pustules, not an acute blistering reaction to a new product.
