What should be done before applying any product to the skin?

Performing a patch test before applying any product to the skin is essential for ensuring client safety. A patch test involves applying a small amount of the product to a discreet area of the skin, usually on the inner arm or behind the ear, and observing for any adverse reactions such as redness, itching, or swelling over a specific period, often 24 to 48 hours. This practice helps to identify any allergies or sensitivities the client may have to the ingredients in the product, preventing potential irritation or allergic reactions during a full application.

While cleansing the skin is a fundamental step in preparing for product application, it does not assess skin sensitivity or allergies. Similarly, while a moisturizer or sunscreen may be important in certain contexts, they do not serve the same preventative function as a patch test. Thus, performing a patch test is a critical step in the process to ensure safe and effective skin treatment.
