Hard water causes acne by depositing high levels of minerals like calcium and magnesium on your skin. These minerals mix with soap and cleansers to form a sticky film that does not rinse off easily.
This film clogs your pores, trapping dirt, oil, and dead skin cells inside. When pores get blocked, bacteria can grow, leading to inflammation and pimples. The residue also dries out your skin by stripping away its natural oils, making it irritated and more prone to breakouts.
You might notice your skin feels tight or sticky right after a shower. Over time, this buildup makes acne worse, especially if you already have oily or sensitive skin. The minerals disrupt your skin’s balance, turning simple washing into a cause of ongoing problems.
Hard water affects everyone differently, but people in areas with mineral-rich water supplies see more skin issues. The soap scum from hard water sticks around, blocking what should be a clean rinse and setting the stage for acne.
