Michigan Esthetician State Board Practice Exam

What is the primary purpose of performing a patch test?

1. Avoid allergic reactions

2. Enhance product effectiveness

3. Test skin sensitivity

4. Promote product absorption

The correct answer is: Avoid allergic reactions

The primary purpose of performing a patch test is to avoid allergic reactions. This test is essential in the skincare and esthetic industry as it helps to identify any adverse reactions that a client may have to specific ingredients in a product before extensive application. By applying a small amount of the product to a discreet area of skin and observing for any signs of irritation, redness, or allergic responses, the esthetician can determine whether the product is safe for use on the client’s skin. This proactive measure plays a crucial role in client safety and comfort, ensuring a positive experience during treatments. While testing skin sensitivity and product effectiveness may seem related, the cornerstone of a patch test primarily revolves around the prevention of allergic reactions, not necessarily evaluating overall product performance or absorption.
