What is the purpose of a patch test?

• A. To determine if a client has an allergic reaction to a product
• B. To ensure the product provides effective results
• C. To check the product’s expiration date
• D. To analyze skin type suitability

Answer: (A)

A patch test is primarily conducted to determine if a client has an allergic reaction to a specific product. This procedure involves applying a small amount of the product to a discreet area of the skin, usually on the inner arm, and observing for any adverse reactions such as redness, swelling, or itching over a specified period, typically 24 to 48 hours. Understanding client sensitivity is crucial in esthetics, as individuals can have varying responses to ingredients found in skincare products. Performing a patch test helps in preventing potential allergic reactions and ensures the safety and well-being of clients. The other options do not encompass this primary function. While effectiveness, expiration, and skin type suitability are important considerations in product use, they do not specifically address the need to identify allergies, which is the main focus of a patch test.
