Question: 1 / 400

What type of skin problem can result from barrier layer damage?

Hyperpigmentation

Scarring

Increased oiliness

Dehydration

When the barrier layer of the skin is damaged, it primarily compromises the skin's ability to retain moisture, leading to dehydration. The stratum corneum, which is the outermost layer of the skin, acts as a protective barrier that helps maintain hydration levels. When this barrier is impaired, moisture can escape more rapidly from the skin, resulting in a lack of hydration and a feeling of tightness or dryness.

Dehydration can also manifest in various visible symptoms such as fine lines, flakiness, and increased sensitivity. The skin may become more susceptible to irritants and environmental factors, which can further exacerbate the condition. Understanding this mechanism is crucial as it highlights the importance of maintaining a healthy barrier layer through proper skin care practices, including moisturizing and avoiding harsh ingredients that can lead to barrier damage.
