Dehydrated skin occurs when the skin lacks moisture, often leading to a tight, dry, or dull appearance. This condition can affect all skin types and is caused by factors like environmental changes, over-exfoliation, inadequate hydration, or harsh skincare products. Unlike dry skin, which lacks oil, dehydrated skin struggles with water retention, leaving it more prone to irritation and fine lines. To restore balance, it's important to focus on hydrating ingredients like hyaluronic acid, glycerin, and ceramides to replenish moisture and help the skin retain it for a smoother, healthier look.
