The signs of dehydrated skin may include fine lines and wrinkles, dull skin, rough or uneven texture, flaking, sensitivity, and even blemishes. Dehydrated skin texture can appear dry, flaky, and dull, and it can be more susceptible to wrinkles and other visible signs of aging. It may also feel tight and uncomfortable. There are a number of ways to help soothe and prevent the signs of dehydrated skin, including drinking plenty of water, using a gentle cleanser, moisturizing dry skin daily, and avoiding harsh skincare, such as retinol or other barrier-compromising ingredients.
