Beauty Therapy Level 2 Practice Test

A common sign of dehydration in the skin is its tight or flaky appearance. When the skin lacks moisture, it can become less pliable and may show physical signs such as tightness or flakes. This occurs because the outer layer of the skin, known as the stratum corneum, loses water and its ability to maintain a smooth texture. Hydrated skin typically looks plump and smooth, while dehydrated skin lacks these qualities. The tightness indicates that skin cells are not adequately filled with water, affecting the overall appearance and feel of the skin.

In contrast, options like oily appearance, bright and glowing skin, and uniform skin tone are indicative of well-hydrated or healthy skin conditions. Oily skin, for example, does not typically relate to dehydration but rather to an excess of sebum production. Bright and glowing skin suggests that the skin is well-hydrated and healthy, while a uniform skin tone indicates an even distribution of pigmentation and moisture. All these attributes are not characteristic of dehydration, thereby reinforcing that the tight or flaky appearance is a clear indicator of a lack of hydration.
