Which factor is NOT typically associated with dehydrated skin?

Dehydrated skin is primarily influenced by environmental and lifestyle factors rather than genetics. When we consider climate conditions, such as low humidity or harsh weather, these can significantly impact the moisture levels in the skin. Similarly, dietary habits play a crucial role in skin hydration; a lack of essential nutrients and water intake can lead to dehydration. Skin type is also relevant, as some skin types may be more prone to dehydration due to their natural oil production levels.

In contrast, genetics dictate the inherent characteristics of the skin, such as its type (oily, dry, combination), but they do not directly determine whether the skin will experience dehydration at any given time. Therefore, genetics is not typically associated with dehydrated skin, making it the correct choice in this context.
