So the ph of most people’s face is between 4.5 and 5.75ph, biore charcoal deep pore cleanser is 4.5-5.5ph supposedly, is maintaining the ph of your face one of the most important parts of a cleanser? Does anyone have any critiques of charcoal products In general? I know they are bad for toothpaste as they wear down enamel. But not sure what to make of it as a cleanser. Using it 15 minutes before applying retin-a.
