What type of ingredients are used to enhance the absorption of other components in cosmetics?

1. Astringents

2. Vehicles

3. Moisturizers

4. Abrasives

The correct answer is: Vehicles

Vehicles are ingredients specifically designed to carry or deliver other active substances deeper into the skin, thereby enhancing their absorption. These substances can create a favorable environment that helps the skin to better absorb the beneficial components of a cosmetic product. In cosmetics, vehicles can include various oils, emulsifiers, or solvents that aid in the effective penetration of other ingredients, allowing them to perform their intended functions more efficiently. In contrast, astringents primarily work by tightening the skin, moisturizers are meant to hydrate and prevent water loss, and abrasives are generally used for exfoliation rather than aiding in absorption. Understanding the role of vehicles helps in selecting the right products for achieving desired skin care outcomes.
