The Science of Skin Hydration: Essential Ingredients for Dewy Skin
Year: 2025
Type: article
Abstract: Skin hydration refers to the process of maintaining an optimal level of moisture within the skin, which is essential for maintaining its health, elasticity, and overall appearance. Natural Moisturizing Factor (NMF) is the naturally occurring substance in stratum corneum which is responsible for skin hydration. Lamellar arrangement of inter-cellular lipids plays effective role of barrier against Trans epidermal water loss (TEWL). This review explores various classes of skin hydrating agents, including humectants, emollients, and occlusives, along with their mechanisms of action. Humectants, such as glycerine and hyaluronic acid, attract moisture to the skin, while emollients like natural oils and ceramides improve skin texture and barrier function. Occlusive agents, such as petrolatum and dimethicone, create a protective layer on the skin to minimize moisture evaporation. The efficacy of hydrating agents is influenced by factors such as personal care products, environmental conditions, excess water and skin type. Recent advancements and plant-derived extracts have further improved the performance of hydrating agents. This paper highlights the importance of selecting appropriate hydrating agents to maintain skin homeostasis and discusses emerging trends in skincare innovation.
