Abstract

Background/aims: The skin protects the body's organs and tissues from damage and physical, chemical and bacteriological injuries. It also prevents the transcutaneous loss of water. The present study was conducted to assess the effects of additional dietary natural mineral water uptake on skin hydration and cutaneous well-being in subjects with dry skin.

Methods: Eighty subjects (44 women and 36 males, mean age 56±5.6 years) were included in the study, randomised per forearm and stratified by gender. Skin surface hydration, transepidermal water loss (TEWL), sorption–desorption test, skin colour, thickness and micro-relief were evaluated on the forearms. Clinical scoring of dryness, roughness and elasticity was performed by a dermatologist.

Results: An improvement of skin hydration was observed after additional water uptake, statistically modifying the hydration level as well as TEWL, the water-binding capacity of the uppermost layers of the stratum corneum. Improvements of softness, smoothness and skin-moisturising effect were perceived by healthy subjects, and skin micro-relief was improved.

Conclusion: We suggest that natural mineral water supplementation may be used in order to improve the hydration of skin dryness as a complementary cosmetic approach.
