What is the effect of humectants on the skin?

Humectants are substances used in skincare products that have the unique ability to attract and retain moisture from the environment to the skin. Their primary function is to hydrate the skin by drawing in water and preventing its loss, making them highly effective in moisturizing and improving the skin's overall texture and appearance. By keeping the skin well-hydrated, humectants can help enhance elasticity, reduce dryness, and promote a more radiant complexion.

While other options such as exfoliating, soothing, and firming may also contribute to skin health, they involve different mechanisms and primary ingredients. Exfoliating agents are designed to remove dead skin cells from the surface, soothing ingredients help to alleviate irritation or inflammation, and firming agents typically work by tightening the skin or boosting its firmness through various compounds. These functions do not directly relate to the primary role of humectants, which centers specifically on hydration.
