A facial cleanser does much more than simply wash. As the essential first step in any skincare routine, its mission is to effectively remove impurities, excess oil, and environmental pollutants while preserving the skin's natural moisture barrier and pH balance. A high-quality cleanser (such as a gentle amino-acid-based formula) should leave skin feeling refreshed and supple—never tight or stripped—after rinsing, perfectly prepping it to absorb subsequent products. Remember, gentle cleansing twice daily is the cornerstone of skin health, while deeper exfoliation should be used periodically (about 1-2 times weekly). Together, they work in harmony to achieve a clean, refined complexion.
