What does hygroscopic mean in relation to skincare ingredients?

Hygroscopic refers to the ability of a substance to attract and hold moisture from the surrounding environment. In relation to skincare ingredients, this means that a hygroscopic ingredient can draw water molecules from the atmosphere, helping to hydrate the skin. This property is particularly beneficial in moisturizers and serums, as it enhances the skin's moisture content and can contribute to a plump and healthy appearance.

While options like absorbing oil, exfoliating dead skin cells, and balancing skin pH are important in skincare, they do not describe the specific action of attracting moisture from the atmosphere. This characteristic is crucial for maintaining skin hydration, especially in products designed to help combat dryness and promote a healthy skin barrier.
