Hard water contains high concentrations of minerals like calcium and magnesium, which can disrupt the skin’s natural moisture balance by leaving a residue that hinders hydration. Research indicates that prolonged exposure to hard water can weaken the skin barrier, increasing transepidermal water loss (TEWL) and leading to dryness and irritation.

By softening the water and eliminating harsh impurities, the filter minimizes calcium and magnesium buildup, which are known to increase transepidermal water loss (TEWL) and lead to dryness.

By removing these irritants, filtered water allows the skin to retain moisture more efficiently, helping to preserve the skin’s protective barrier and support better hydration. Clinical findings suggest that softer, purified water can enhance the absorption of beneficial skincare ingredients and reduce the risk of irritation caused by hard water residues.
