Nutrition and water: drinking eight glasses of water a day ensures proper skin hydration-myth or reality?

Author information

Dermatology Unit, Kaplan Medical Center (affiliated to the Hebrew University - Hadassah Medical School, Jerusalem), 76100 Rechovot, Israel.


How-to books, beauty journals, the Internet, and the media usually recommend drinking six to eight glasses of water each day for keeping the skin hydrated, helping it look healthier, and making it less prone to wrinkles. We have found no scientific proof for this recommendation; nor is there proof, we must admit, that drinking less water does absolutely no harm. The only certainty about this issue is that, at the end of the day, we still await scientific evidence to validate what we know instinctively to be true--namely, that it is all a myth.
