The replacement to your double-cleanse, the Barrier Culture Cleanser deeply cleans the skin, removing dirt, pollution and makeup without stripping or disrupting the skin's PH. This soap- and sulfate-free formula actively repairs the skin barrier and replenishes your topical microbiome by using pre, pro and postbiotics, proven to help prevent breakouts, unclog pores and keep your skin smooth and nourished. The Nue Co.'s patented probiotic technology in the formula is clinically proven to defend the skin against damage from pollution, improve skin moisturization and strengthen the skin barrier. This low pH cleanser (pH 5) matches the naturally slightly acidic pH of healthy skin (around pH 4.5 - 5). Unlike most foaming or wash-off cleansers, it doesn't push the skin into an alkaline state which can cause breakouts, sensitivity and irritation.
