What is the likely cause of dry, cracked skin?

The correct answer highlights dehydration of the skin as a primary cause of dry, cracked skin. When the skin lacks moisture, it becomes less elastic and more prone to damage. This dehydration can result from various factors, such as environmental elements (like cold weather or low humidity), insufficient water intake, or the use of harsh skincare products that strip the skin of its natural oils.

Dehydrated skin often appears flaky and can lead to discomfort, emphasizing the importance of maintaining proper hydration both internally and externally. To combat dryness, it is recommended to use moisturizers that help retain moisture, increase water intake, and protect the skin from elements that could exacerbate the condition.

While excess oil production, allergic reactions, and excessive sun exposure can impact skin health, they do not primarily lead to the specific condition of dry and cracked skin as dehydration does. Excess oil can create a different set of issues, allergic reactions typically involve rashes or irritation rather than dryness, and while sun exposure can cause skin damage, it usually results in other symptoms like sunburn or pigmentation changes rather than the straightforward cracking associated with dehydration.
