Which term describes a product's ability to produce favorable results?

• A. SDS
• B. Immunity
• C. Efficacy
• D. Level

Answer: (C)

Efficacy describes a product's ability to produce favorable results. It refers to how well the product achieves its intended benefits under controlled conditions, such as clinical or lab testing, where measurable improvements are demonstrated. In skincare, proving efficacy means trials show real benefits like smoother skin, reduced wrinkles, or better hydration. Safety data sheets (SDS) cover safety and handling, not performance. Immunity is about the body's defense against pathogens, not how a cosmetic product works. Level is too vague to describe a product’s actual performance. So, the term that best describes a product’s ability to yield favorable results is efficacy.
