What skin problem can result from a lack of proper hydration?

A lack of proper hydration primarily results in dehydrated skin. Dehydration occurs when the skin lacks sufficient water content, leading to an imbalance that manifests as dullness, tightness, or a feeling of dryness. In a dehydrated state, the skin may also appear more prone to fine lines and wrinkles, as well as increased sensitivity and irritation.

While the other options might relate to different skin concerns, they do not directly stem from inadequate hydration. For example, oily skin is characterized by excess oil production, which is not caused by lack of hydration but rather by factors like hormonal imbalances or overactive sebaceous glands. Dry patches can occur due to various reasons, including environmental factors or skin conditions, but they do not encapsulate the broader state of overall dehydration. Acne breakouts are typically linked to overproduction of oil and clogged pores, rather than directly caused by a lack of hydration. Therefore, the most accurate choice regarding the consequences of insufficient hydration is dehydrated skin.
