Humectants are key ingredients used in skincare formulations that focus on maintaining skin hydration. Their primary function is to draw moisture from the environment into the skin, which helps to keep the skin adequately hydrated and plump. This characteristic makes them essential for individuals with dry skin, as they aid in reducing moisture loss and ensuring that the skin remains smooth and supple. Other ingredients, such as oils, are primarily used for their emollient properties, which help to soften and smooth the skin by forming a barrier that locks in moisture but do not attract water. Waxes are used in formulations to provide structure and stability, while surfactants are used mainly in cleaning products to reduce surface tension but are not primarily concerned with hydration. Thus, humectants stand out for their unique ability to attract and retain moisture in the skin.
