What is an emollient?

An emollient is defined as a substance that softens and smooths the skin. Emollients play a critical role in skincare by creating a barrier on the skin's surface, which helps to retain moisture and prevent dryness. This is particularly important for maintaining skin health, as well-hydrated skin is less prone to irritation and appears smoother and more supple.

In contrast, substances that remove impurities are categorized as cleansers, which specifically target dirt and excess oil. Similarly, substances that promote hair growth are often referred to as hair stimulants or growth serums and are formulated for that specific purpose. Lastly, substances used in coloring hair, such as dyes and pigments, are designed to alter hair color and do not serve the function of softening or smoothing the skin. This illustrates the specific role emollients have within skincare and cosmetic formulations, focusing on skin texture and hydration.
