Greatly enhances the effectiveness of all moisturizers and any skin care regimen. Convenient size-- perfect for office. Propelled under high pressure by nitrogen (80% of the air we breathe is nitrogen, 20% oxygen), the ultra-fine pure, natural mist allows the skin to absorb a unique balance of beneficial minerals along with the water. No other water contains the same balance of magnesium, calcium and phosphorous in the same proportion as human blood which explains Evian's superb compatibility with facial skin. The 5 oz. size lasts over a month and should be a daily part of every woman's skin care regime which is why many say the French may have discovered the fountain of youth.
