COSRX Low pH Niacinamide Micellar Cleansing Water is a daily facial cleansing wash designed to gently remove impurities, makeup, and excess sebum without stripping the skin’s natural moisture barrier. Formulated with a low pH level, this micellar water helps maintain the skin’s optimal acid balance, making it suitable for sensitive skin types. The inclusion of niacinamide, a form of vitamin B3, works to support skin clarity and sebum control, while also contributing to a more even skin tone over time.

This product features a mild, non-irritating formula that relies on micelle technology to lift away dirt and oil from the skin’s surface without the need for harsh rubbing or rinsing. It is free from alcohol, parabens, and artificial fragrances, reducing the risk of irritation for those with reactive or easily sensitized skin. The lightweight, water-like texture leaves the skin feeling refreshed and hydrated, not tight or greasy.

The cleansing water is particularly suited for individuals with combination, oily, or acne-prone skin, as it helps regulate sebum production without over-drying. It can be used as a first step in a double-cleansing routine or as a standalone cleanser for lighter makeup days. The 100ml bottle offers a practical size for travel or daily use at an accessible price point, aligning with the brand’s focus on effective yet affordable Korean skincare solutions. Regular use may contribute to a clearer, more balanced complexion when incorporated into a consistent skincare regimen.
