If a client is allergic to pineapple, where should you check for its presence in products?

When a client has an allergy to a specific ingredient such as pineapple, it is crucial to verify the presence of that ingredient in any products that may be used during treatments. The Safety Data Sheet (SDS) is a comprehensive document that provides detailed information about the properties of a chemical substance or mixture, including hazards, handling, and components. It will explicitly list ingredients that may not be found on the product label or packaging, particularly if they are used in smaller quantities or as components of other formulations.

The SDS is essential for understanding the full context of safety and handling procedures, as well as recognizing any potential allergens. Thus, when checking for ingredients that might trigger an allergic reaction, the SDS serves as a critical resource for ensuring client safety and preventing adverse reactions.

While the product label and ingredient list on packaging are also important resources, they can sometimes lack comprehensive information, particularly if the product contains proprietary blends. The consultation form does provide necessary background information about the client's allergies, but it does not contain detailed product ingredient lists or safety information. Therefore, the Safety Data Sheet is the most reliable source to confirm the presence of pineapple in products used during esthetic procedures.
