What is the primary function of moisturizers in skincare?

The primary function of moisturizers in skincare is to hydrate and protect the skin. Moisturizers work by helping to retain moisture within the skin barrier, which is essential for maintaining healthy skin. They often contain a combination of humectants, emollients, and occlusives that work together to attract water to the skin, soften the skin, and create a protective layer that prevents moisture loss.

Hydration is crucial because dry skin can lead to various problems, including irritation, flaking, and an overall rough texture. By providing essential moisture, moisturizers help to support the skin's natural barrier, making it less susceptible to environmental stressors and promoting a smoother, more elastic appearance.

While exfoliation, removal of impurities, and sun protection are important aspects of a comprehensive skincare routine, they are not the primary function of moisturizers. Exfoliation focuses on sloughing off dead skin cells, cleansing products target dirt and oil removal, and SPF formulations safeguard against UV damage. Each has its distinct purpose and function within skincare but does not encompass the core role of moisturizers.
