Dehydrated skin is a condition that occurs when the skin lacks water, which can make it feel tight, appear flaky, and look tired. Dry skin, on the other hand, is a skin type characterized by low oil (sebum) production, often leading to persistent roughness and irritation. Dull skin typically happens when there is a buildup of dead skin cells, reduced circulation, or exposure to environmental stressors like pollution or sun damage. While these issues may be temporary, they can become more noticeable or persistent without proper skin care. Unlike dry skin, which is a skin type, dehydration can affect anyone and is often linked to external factors such as weather, diet, or inadequate hydration. Recognizing the difference is key to choosing the right treatments and restoring a radiant, healthy glow.
