Skin barrier: five signs dermatologists say may show damage.

Dermatologists identify five signs that can indicate a damaged skin barrier and link common causes to overuse of active topicals, hot water, and environmental stressors.

The skin barrier is the stratum corneum, the outermost layer of skin that helps retain moisture and shield against irritants. Dermatologists in the article outline five signs that may point to a compromised barrier. They describe common contributors such as overuse of active topical ingredients, very hot water, sun and cold exposure, and abrasive cleansers. Experts also note that barrier disruption can increase inflammation and alter the skin microbiome. Key observations: - The skin barrier is made of skin cells and lipids and acts to prevent moisture loss and limit penetration of irritants. - Common disruptors include overuse of actives (for example using multiple strong actives too quickly), very hot water, sun damage, pollution, cold weather, and abrasive or stripping cleansers. - Five signs highlighted by experts are increased sensitivity or burning with normally gentle products; perioral dermatitis (redness and itching around the mouth and nose); peeling or splitting after picking; persistent dryness and loss of bounce; and acne-like flares, papules, or redness. - The article reports that dermatologists and aestheticians advise simplifying routines and using gentle cleansers and barrier-supportive ingredients such as ceramides, fatty acids, glycerin, and centella, and that barrier creams were noted as an accessible option. - Lifestyle factors mentioned by experts include dietary essential fatty acids, probiotics, use of a humidifier in dry seasons, prioritising sleep, and stress management as supportive to recovery. Summary: Dermatologists describe five signs that can indicate a damaged skin barrier and link common causes to topical overuse and environmental stressors. The article reports experts recommending simplification of skincare routines and the use of barrier-supportive ingredients and barrier creams to aid recovery. Recovery timelines and specific treatments are not specified in the article.
