The pH of skin influences several factors to an overall health. It’s been demonstrated that skin with pH values below 5.0 are healthier, more hydrated, and have a stronger barrier function than those above 5.0.pH
pH stands for the “potential of hydrogen,” and how concentrated hydrogen ions are in a solution.
Our skin is protected by something called the “acid mantle.” It is a small film on the surface of the stratum corneum composed of fatty acids, lactic acid, pyrrolidine carboxylic acid, amino acids, and a bunch of other scientific terms.
This acid mantle is what gives our skin its pH, and ranges anywhere from 4.0 to 7.0, with the average being 4.7. It protects our skin from bacteria, fungi, viruses, environmental pollutants, makes skin soft and supple.
