Here is a quick post about pH.
What is pH❓ pH is a scale used to measure acidity. The scale goes from 0 to 14; the smaller the number, the more acidic the substance. The greater the number the more basic or alkaline.
pH of a “healthy” skin is slightly acid (4.5-5.9) in order to defend itself against bacteria. Skin with acne normally has a pH between 7-8.
Washing our skin with a basic soap will leave it with a basic pH, favoring acne, irritations, and other skin problems.
🌸 Tip: After using an alkaline cleanser, it is advisable to use a toner with an acidic pH.
With an acidic cleanser, our skin will remain with an acid pH, allowing the growth of pathogenic organisms.
