ISOI PHA Mild Deep Cleansing Foam is a gentle daily face cleanser formulated with a polyhydroxy acid (PHA) complex, designed to provide mild exfoliation while maintaining hydration. This Korean skincare product targets sensitive skin types, offering a deep cleansing action without stripping the skin’s natural moisture barrier. The PHA ingredient works by loosening dead skin cells and impurities on the surface, supporting a smoother texture over time, while its larger molecular structure makes it less irritating compared to stronger exfoliating acids. The formula includes hydrating components to counterbalance the cleansing process, leaving skin feeling refreshed rather than tight or dry. This foam is suitable for individuals seeking a non-abrasive exfoliation option, particularly those with reactive or easily dehydrated skin. It comes in a 3.38 fl.oz (100ml) tube, making it convenient for daily use in a skincare routine. The product is free from harsh surfactants, focusing instead on a mild, creamy lather that rinses away makeup residue, excess oil, and environmental debris. Its texture is lightweight and non-greasy, allowing for easy application and removal. As part of a broader Korean skincare approach, this cleanser aims to support skin clarity and comfort through consistent use, emphasizing a balanced cleansing experience that respects sensitive skin’s needs. The PHA concentration is kept at a level intended for regular application, making it a practical choice for those who prefer gradual exfoliation without aggressive treatments. This product is best integrated into a morning or evening routine, followed by toner and moisturizer, to maintain skin health and resilience.
