What are vehicles in the context of skincare?

In the context of skincare, vehicles refer to substances that serve as a medium to help deliver performance ingredients into the skin. These are typically formulated to carry active ingredients effectively and can also assist with the overall texture and application of a product. Vehicles ensure that the active ingredients are distributed evenly and can penetrate the skin barrier more efficiently.

By diluting performance ingredients, vehicles help in achieving an appropriate concentration for topical application, which can enhance the absorption and efficacy of the active components within the formulation. This is crucial for the effectiveness of skincare products, as it allows the beneficial ingredients to work optimally while minimizing the risk of irritation from overly concentrated formulations.

The other choices relate to different aspects of skincare formulation but do not align with the definition of vehicles in this context. For example, enhancing fragrance or adding color does not relate to the role of a vehicle in ingredient delivery, while active ingredients that fight acne are specific components rather than vehicles themselves.
