Both will turn white. When white acetate is applied to inflamed skin, it may cause the inflamed area to turn white. This is because Acetowhite has some antibacterial and anti-inflammatory properties that can help reduce the symptoms of inflammation. Acetowhite inhibits the inflammatory response and reduces vasodilatation and oozing, thus relieving tissue swelling and redness, which in turn reduces the blood supply to the inflamed area and causes the skin to become paler in color.
