The main side effects of long-term facial cleansing with white vinegar include irritation of the facial skin and potential development of skin conditions, such as rashes. It is recommended to reduce the frequency of using white vinegar for facial cleansing. Moreover, avoid applying undiluted white vinegar directly to the face; instead, add approximately 7–10 drops of white vinegar to your facial cleansing water. Direct application of undiluted white vinegar significantly increases skin irritation.
