Dehydrated skin occurs when the skin lacks sufficient moisture, which can lead to a number of problems, including changes in skin texture. When the skin is dehydrated, it can become dry, rough, and flaky, making it appear dull and uneven. Additionally, it can also cause the skin to produce excess sebum to compensate for the lack of moisture. This excess oil production can clog pores, forming blackheads and acne, which can further contribute to changes in skin texture. To improve skin texture caused by dehydration, it's important to hydrate the skin from within and on the surface. This can be achieved by drinking plenty of water, using a moisturizer that contains ingredients such as hyaluronic acid or glycerin, and avoiding harsh cleansers or exfoliants that can strip the skin of its natural oils.
