The current Migaku evidence database contains 2 reusable source documents for Vitamin A Skin Hydration Randomized Trial. This answer focuses on benefits, uncertainty, and practical interpretation. - Abnormalities in aquaporin 3 (AQP3) expression and associated deficits in skin hydration appear to have a role in atopic dermatitis and psoriasis. [Camilion JV (2022); evidence level 4] - AQP3 hydration-related aspects are influenced by circadian rhythms via modulations associated with CLOCK genes that alter AQP3 protein expression. [Camilion JV (2022); evidence level 4] - Ultraviolet exposure, aging, and low temperatures are among those factors that affect skin ceramide composition, potentially leading to increased transepidermal water loss and negatively impacting skin hydration. [Camilion JV (2022); evidence level 4] - Thismanuscript focuses on the physiological, environmental, nutritional, circadian, and aging factors affecting skin tissue water and hydration parameters. [Camilion JV (2022); evidence level 4] - In conclusion, to properly moisturize and lubricate the skin, young women should eat products that are rich in ingredients with antioxidant properties, in particular fat-soluble vitamins A and E, but also copper.
