The term that refers to the ability to produce an effect is "efficacy." Efficacy is specifically used to describe the capacity of a product, treatment, or procedure to provide the desired result under ideal conditions. In esthetics and dermatology, when discussing products or treatments, efficacy is paramount because it indicates whether an intervention can achieve its intended target, such as reducing acne, improving skin texture, or enhancing hydration.

The distinction between efficacy and similar terms like effectiveness is important. Effectiveness pertains to how well a product works in real-world settings and may incorporate factors like patient compliance and varied skin types. Efficiency relates to the optimal use of resources to achieve the desired outcome, while action simply denotes the process of doing something and does not inherently relate to the outcome produced. Understanding these definitions is essential for estheticians to make informed recommendations and assess the products they use.
