Diabetic dry skin, also known as xerosis, is a common complication among individuals with diabetes mellitus (DM). This condition arises due to various factors associated with diabetes, including chronic hyperglycemia, which leads to increased advanced glycation end-products (AGEs), proinflammatory cytokines, and oxidative stress. These factors collectively impair the skin's natural barrier, leading to dryness, scaling, and increased susceptibility to infections.
Chronic hyperglycemia in diabetes results in the formation of AGEs, which contribute to skin stiffness and impaired wound healing by affecting collagen in the dermis. Additionally, hyperglycemia induces oxidative stress and inflammation, further compromising the skin barrier . In type 1 diabetes, increased transepidermal water loss (TEWL) and reduced collagen IV levels are observed, while in type 2 diabetes, particularly in obesity models, histamine release and hyaluronidase activity lead to decreased hyaluronic acid levels, contributing to skin dryness.
The mechanisms of skin dryness differ between type 1 and type 2 diabetes. In type 1 diabetes, the primary issues are increased TEWL and reduced collagen IV due to AGEs and matrix metalloproteinase-9 activity. In type 2 diabetes, especially in obesity models, the release of histamine and hyaluronidase by mast cells reduces hyaluronic acid levels, leading to dry skin . Non-obesity type 2 diabetes models show increased inflammatory cytokines, which may disrupt skin collagen.
Dry skin in diabetic patients is not just a cosmetic issue but a significant risk factor for more severe complications such as diabetic foot ulceration (DFU). Studies have shown that dryness of foot skin, assessed by the visual indicator plaster method (IPM), is a strong predictor of DFU development. This highlights the importance of early detection and management of dry skin to prevent serious complications.
Dry skin and associated pruritus significantly impact the quality of life in diabetic patients. Effective management of these symptoms can lead to substantial improvements in patient well-being. For instance, the use of specific dermo-cosmetic products has been shown to reduce skin dryness, pruritus, and insomnia, thereby enhancing the quality of life for diabetic patients.
Combining oral and topical treatments can effectively manage dry skin in diabetes. For example, Centella asiatica (CA) has been shown to improve dry skin conditions in type 2 diabetes patients by increasing superoxide dismutase (SOD) activity and reducing inflammatory markers. This combination therapy can significantly enhance skin hydration and barrier function.
Regular use of gentle cleansers and moisturizers is crucial for managing diabetic dry skin. Products containing anti-aging ingredients, urea, and essential ceramides can help restore the skin barrier, reduce dryness, and prevent complications. Adherence to a consistent skincare routine is essential for maintaining skin health in diabetic patients.
Preventive measures, including regular skin assessments and early intervention, are vital in managing diabetic dry skin. Educating patients about the importance of skin care and the use of appropriate products can prevent the progression of skin complications and improve overall outcomes .
Diabetic dry skin is a multifaceted issue that requires a comprehensive approach to management. Understanding the underlying mechanisms, recognizing the clinical implications, and implementing effective treatment strategies are essential for improving the quality of life in diabetic patients. Regular use of moisturizers, combined with targeted therapies like Centella asiatica, can significantly alleviate symptoms and prevent severe complications such as diabetic foot ulceration.
