What is the primary function of skin moisturizers?

The primary function of skin moisturizers is to moisturize the skin. Moisturizers are designed to provide hydration, improving skin texture, elasticity, and overall appearance. They work by creating a barrier on the skin that helps to lock in moisture and prevent water loss, which is critical for maintaining healthy skin.

When used properly, moisturizers can help alleviate dryness, flakiness, and irritation, making the skin feel softer and more comfortable. Ingredients commonly found in moisturizers, such as hyaluronic acid, glycerin, and natural oils, are specifically chosen for their ability to attract and retain moisture in the skin.

While some products may offer additional benefits like exfoliation, sun protection, or cleansing, the primary role of a moisturizer is fundamentally about hydration. It’s essential for maintaining the skin's moisture balance, which can be affected by factors like climate, age, and skin type.
