Which ingredient serves as a performance and delivery system in skincare?

The ingredient that serves as a performance and delivery system in skincare is emollients. Emollients are substances that help to soften and smooth the skin, creating a protective barrier that locks in moisture. They play a crucial role in enhancing the absorption and effectiveness of other ingredients within a product. By providing a suitable medium, emollients facilitate the distribution of active ingredients over the skin and improve the overall texture and feel of the formulation.

In addition to their primary function of moisturizing, emollients can enhance the penetration of various skincare actives, allowing them to deliver their benefits more effectively. This makes emollients vital in skincare formulations as they not only provide hydration but also support the optimal functionality of other components within the product.
