M-KIN ACN OS Serum secured KTR proof data on natural materials (raw materials) developed by Rock Biotech and proved product performance through human application tests (KTR clinical trial studies) on redness, oil, and sebum improvement. It is suitable for sensitive skin and skin where excessive sebum or oil is secreted. In addition, since pH is 5.5 with a weak acidity, it is good to use because it is the same as the weak acidity condition of healthy skin.
