Proper hydration should be the cornerstone of any skincare routine. One of the culprits of aging skin is dryness. Whether you experience dryness due to hormonal changes, the environment or age, it can make skin look older. In fact, research shows that dry skin actually behaves like older skin. As the outer surface becomes dry, cell turnover reduces which results in skin that is more prone to sensitivity, lines and wrinkles, and is less receptive to skincare products. As skin ages, it requires more hydration to perform optimally, and can become more difficult for skin to take in hydration or other skincare ingredients.
