Using invasive sampling methods, such as bronchoalveolar lavage (BAL) or transtracheal aspiration (TTA), the LRT has been shown to host a low-biomass core microbiota dominated by Pasteurellaceae, Mycoplasmataceae, Flavobacteriaceae, Clostridiaceae, and Prevotellaceae, while archaea, viruses, and eukaryotic microbes are rarely reported (Table 1) 8,110,111,112
Common reasons include: Lack of natural oils: Dry skin produces less sebum, reducing protection Environmental factors: Cold weather, low humidity, pollution, and indoor heating Ageing: Ceramide and lipid levels decline with age Poor skincare habits: Over-cleansing, harsh products, hot water Dehydration: Not drinking enough water affects skin from within Because dry skin is both an external and internal issue, it often needs more than just surface-level care
