Use the **HIDIFF Royal Mildly Acidic Cleansing Foam** morning and evening on damp skin. Lather a small amount between your hands, then gently massage your face in circular motions, especially the T-zone. Rinse thoroughly with lukewarm water, then follow with your lotion/toner and usual K-Beauty routine. Its mildly acidic formula respects the skin barrier, making it ideal for gentle daily cleansing.
