Dietary water seems to improve skin hydration without influencing hemodynamics

subject

description

The various studies on the importance of water in the hydration of human skin have suggested that an increased dietary intake might positively impact the physiology of normal skin. We evaluated the consequences of increasing water intake through drinking in skin hydration in vivo. Eating habits were maintained, evaluated by a Food Frequency Questionnaire and based on total water consumption. In two groups with different total water consumption, we evaluated the impact of 2L/day water after 30 days,. This increase produced no hemodynamic changes or weight changes but an improvement in the epidermal hydration was suggested. The magnitude of the impact on skin hydration was higher in the group that regularly consumed less water, suggesting that the increase in water consumption has more beneficial effects on those individuals who habitually consume less water per day. These data are consistent with the published literature, justifying interest in looking further into this topic, in order to better understand the importance of dietary water in the context of cutaneous physiology, especially in the group of subjects with reduced consumption habits.
