How long does it take to whiten skin and fade acne marks?
According to several human experiments taking vitamin C at present, the skin's anti-oxidation ability is improved in about one month (significant changes are detected at the molecular level, such as the activity of antioxidant enzymes such as SOD will increase), but no obvious changes can be seen by naked eyes. The changes visible to the naked eye take three months or even half a year, including skin spots becoming smaller and lighter and texture improving. So if you want to get rid of acne marks and whiten, you still have to take it orally for a while.
