What does skin hydration primarily involve?

Skin hydration primarily involves maintaining moisture content in the skin. This is essential for keeping the skin healthy and functioning properly. Hydrated skin appears more plump, is less prone to irritation, and can better defend against environmental stressors. The skin's barrier function is significantly influenced by its hydration levels; when adequately hydrated, the skin can effectively retain moisture and protect underlying layers from damage.

While exfoliating dead skin cells can improve the appearance of skin texture and remove barriers to hydration, it is not the primary focus of skin hydration. Similarly, applying anti-aging serums and using chemical peels may contribute to overall skin health but do not specifically address the fundamental need for moisture retention in the skin. Thus, the correct understanding of skin hydration emphasizes the importance of keeping the skin's moisture content balanced for optimal health and appearance.
