What is the primary benefit of using a moisturizer?

Moisturizers play a crucial role in skincare by primarily providing hydration and supporting the skin's barrier function. The skin’s outermost layer, known as the stratum corneum, can become dry and compromised due to various environmental factors and natural aging processes. A good moisturizer contains ingredients designed to attract and retain moisture in the skin, which is essential for maintaining skin elasticity and overall health.

By hydrating the skin, moisturizers help in creating a protective barrier that minimizes water loss, potentially reducing the chances of irritation and dryness. A well-hydrated skin barrier is vital in preventing issues such as flakiness, rough texture, and increased sensitivity. This hydration not only enhances skin appearance but also improves its resilience against environmental stressors, thereby contributing to healthier skin overall.

This function distinctly differentiates moisturizers from other products that may aim to cleanse, control oil production, or otherwise negatively impact skin health. For instance, while cleansing products are designed to remove dirt and impurities, they do not provide hydration. Similarly, some products may target oiliness or address aging concerns, but their primary functions are divergent from the central purpose of moisturizers.
