Question: can drinking carbonated water cause acne?
Answer: Why Cleansing With Carbonated Water Works... Tap water typically has a pH of 7, while sparkling water has a pH of 5.5, which is also the pH of your skin, so it won't irritate your face. The carbonation works to break up dirt, oil, and impurities in clogged pores, resulting in a deeper clean (and less breakouts).
