HOW PH AFFECTS THE SKIN
Many people tend to lean towards citrus fruits like lemon and grapefruit for DIY skin care remedies, that’s because citric acid is an alpha hydroxy acid. These acids contain glycolic acid and lactic acid and are often used as skin peels. However, the citric acid found in citrus fruits is at a higher concentration of 5-10% than that of a skin peel AND has a pH of about 2-3!!! Whoa!
