What can result from a compromised barrier function in the skin?

• A. Excess oiliness
• B. Dehydration and irritation
• C. Improved absorption of products
• D. Brittle hair

Answer: (B)

A compromised barrier function in the skin can lead to dehydration and irritation due to the skin's inability to effectively retain moisture and protect against environmental irritants. The skin barrier, primarily composed of corneocytes and lipids, serves as a protective layer. When this barrier is damaged or weakened, it allows for trans-epidermal water loss (TEWL), resulting in dryness and an increase in sensitivity to irritants, allergens, and pathogens.

This condition can manifest as symptoms such as redness, flaking, and overall discomfort. The skin may also become more susceptible to infections or inflammatory skin conditions, as the protective role of the barrier is compromised. Thus, the effects of compromised barrier function are significant in terms of skin health and overall integrity, making dehydration and irritation the key concerns in this context.
