The Purito Defence Barrier pH Cleanser is a gentle, non-irritating formula that is great for all skin types. It is especially recommended for those with dry skin, as its low pH of 5.5 does not disturb your skin's natural acid mantle. Acid mantle is a very thin, acidic film on your skin's surface that helps protect it from harmful contaminants such as bacteria, viruses, and pollutants. High pH cleansers can strip this acid mantle, leading to the tight, squeeky-clean feeling on your skin. The Purito Defence Barrier pH Cleanser contains Tea tree Leaf Oil, Centella Asiatica extract, Royal Jelly extract, and Grapefruit Extract to gently cleanse and exfoliate your skin.
