Citric Acid: Citric acid for the right pH value

Citric acid is used in very small amounts to stabilize an acidic pH value in skin care products.

A slightly acidic pH value between 5 and 6 is very important for healthy skin, as it preserves our skin's microbiome and the natural acid mantle that protects us from harmful microorganisms. For this reason, we also advise against soap , as it has a pH value that is too high (alkaline). Xeno products have a pH value that is adapted to the skin.

Pure citric acid would act as an extremely strong exfoliant and severely irritate the skin. However, in small quantities (as used in skincare products), citric acid is completely harmless.
