What is the main purpose of an emollient in skin products?

The primary function of an emollient in skin products is to soften and soothe the skin. Emollients are vital ingredients that help to maintain the skin's moisture barrier, providing a protective layer that prevents water loss and improves skin texture. By doing so, they not only enhance the skin's appearance but also provide comfort, especially for those dealing with dryness or irritation. This quality of emollients makes them essential for formulations targeting dry, sensitive, or flaking skin conditions, ensuring that the skin feels smooth and supple after application.

In contrast, while some products may aim to increase absorption of active ingredients or contain exfoliating components, the specific role of an emollient is focused on moisture retention and skin conditioning. Enhancing fragrance might improve aesthetic appeal, but it does not contribute to the fundamental purpose of emollients in skincare formulations. Therefore, the correct answer emphasizes the soothing and softening characteristics that emollients provide to the skin.
