Relationship between the dietary intake of water and skin hydration

Several studies about the importance of water in the hydration of the human skin suggest that higher water intake might have a positive impact on the skin. When measuring water consumption, it must be taken into account that the water comes from various sources. With this in mind, we evaluated the impact of an increased inflow of 2L of water per day, on two groups with different daily water intakes. Results suggest that there is an improvement in the epidermal and dermal hydration obtained by standard methods. The magnitude of this impact on skin hydration is greater in the group that regularly consumes less water. This suggests that an increase in water consumption has more beneficial effects on the skin health of those individuals that consume less water per day. These data are consistent with the published literature, which therefore justifies further research into this topic

Impact of excess body weight on skin hydration and biomechanics

© Springer International Publishing Switzerland 2015. P. Humbert et al. (eds.), Measuring the SkinThe WHO regards obesity as an epidemic, affecting more than one third of adults in the United States. Obesity is a key factor for several comorbidities, and naturally, the skin is a major organ involved. This study aims to add knowledge to the characterization of skin functional changes related with excessive body weight. A sample of 30 healthy female volunteers, 29–46 (36 ± 4) years old, was selected and divided into three groups dependent on their respective body mass index (BMI) – Group I with BMI between 19.9 and 24.9 kg/m2, Group II with BMI between 25 and 29.9 kg/m2, and Group III with BMI between 30 and 39.9 kg/m2. Skin physiology was assessed by transepidermal water loss (TEWL), epidermal hydration (barrier function), and biomechanical descriptors (“envelope” function). Results have shown that excessive body weight compromises both the barrier function and the biomechanical behavior, but the magnitude depends on the severity of obesity and the anatomical area considered. Nevertheless, further studies are still needed to better understand this pathophysiology’s impact on human skin.info:eu-repo/semantics/publishedVersio

Excessive weight favours skin physiology : up to a point : another expression of the obesity paradox

© 2017 S. Karger AG, BaselBackground/Aims: Recently classified as an epidemic by the WHO, obesity (as well as the state of being overweight) clearly affects significant populations across all ages. The relationship between obesity and some diseases (e.g. cardiovascular ones) is known, although many paradoxes remain to be explained. Very little information is available, however, regarding its impact on skin physiology and skin disease. This study aims to examine the influence of excessive weight on epidermal hydration and transepidermal water loss, key variables of skin water balance and skin biomechanics. Methods: A convenience sample of 89 healthy female volunteers was selected and divided into 4 groups, according to their BMI (body mass index), as normal (control), overweight, obese (I and II), and morbid. Skin physiology was quantitatively assessed in all individuals in 4 anatomical areas using non-invasive biometrical analysis by reference instrumentation. Descriptive and comparative statistics were applied, adopting a confidence level of 95%. Results: A nonlinear alteration for all variables was detected as a function of BMI. Conclusion: Results suggest that excessive weight might favour skin performance within certain limits, reflecting a particular adaptation of the skin to the weight gain and body contour.info:eu-repo/semantics/publishedVersio

Dietary water seems to improve skin hydration without influencing hemodynamics

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
