What is the primary goal of using a patch test?

The primary goal of using a patch test is to check for allergic reactions before using a new product. This involves applying a small amount of the product to a discreet area of the client's skin, usually behind the ear or on the inner forearm, to monitor for any adverse reactions. This precaution is vital as it helps to identify any allergies or sensitivities the client may have to specific ingredients in the product, ensuring their safety during subsequent treatments or applications. Conducting a patch test not only protects the client from potential discomfort or health risks but also helps the cosmetologist tailor their services to meet the individual needs of the client effectively.
