What type of solution has a pH level of 7?

A solution with a pH level of 7 is considered neutral. This means it is neither acidic nor basic; it has an equal concentration of hydrogen ions (H+) and hydroxide ions (OH-). The pH scale ranges from 0 to 14, where values below 7 indicate acidity, and values above 7 indicate alkalinity. Pure water, for instance, has a pH of 7, making it the standard reference for neutrality. Understanding pH is essential in beauty therapy because it can influence the effectiveness and effects of various skincare products and treatments, which may be formulated to be acidic or basic for specific purposes. In this case, a neutral solution is vital for processes that require a balanced environment, ensuring that skin and product interactions remain optimal.
