What is the primary function of skin moisturizers?

The primary function of skin moisturizers is to hydrate and protect the skin. Moisturizers contain ingredients that help to attract water to the skin, preventing it from becoming dry and maintaining its natural moisture balance. This hydration is crucial for keeping the skin looking healthy, plump, and youthful. Additionally, moisturizers form a protective barrier on the skin's surface, which helps to shield it from environmental factors such as pollution and harsh weather that can lead to dryness and irritation.

When it comes to hydration, moisturizers typically include humectants, occlusives, and emollients. Humectants draw moisture from the environment or deeper layers of the skin, occlusives create a physical barrier to prevent water loss, and emollients help to smooth and soften the skin. Collectively, these components contribute to the overall health and appearance of the skin by ensuring that it remains hydrated and well-protected against potential damage.
