What are the signs of impaired skin barrier?

Signs of impaired skin barrier mainly include the following aspects: 1. Dryness and peeling: The skin loses its protective ability, leading to accelerated water loss, resulting in localized dryness, flaking, and scaling. 2. Hypersensitivity: A damaged skin barrier compromises immune function, making the skin overly sensitive and prone to reactions such as redness, swelling, and itching. 3. Redness and visible capillaries: After skin barrier damage, the stratum corneum becomes thinner and capillaries are more likely to dilate, causing facial redness and even visible blood vessels. 4. Skin burning sensation: A compromised skin barrier fails to protect the dermis effectively, making the dermal tissue susceptible to irritation and causing a burning sensation. 5. Other symptoms: These may include stinging, small red rashes, enlarged pores, and increased oiliness.
