What does pH stand for?

pH stands for "Potential Hydrogen." This term reflects the concentration of hydrogen ions (H+) in a solution and is a measure of its acidity or alkalinity. The science behind pH is that it is a logarithmic scale ranging from 0 to 14, where a pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline. The "potential" aspect describes how much potential the hydrogen ions in the solution have to affect the pH level.

Understanding pH is crucial in skin science because the skin's barrier function, overall health, and the efficacy of skincare products can be significantly influenced by the pH of the skin and the products applied to it. An imbalanced pH can lead to issues like irritation, breakouts, or compromised barrier function.
