While it may seem counterintuitive, splashing your skin with tap water or rinsing your face in the shower is not beneficial for your skin.
The reason for this is that the water from the tap is often “hard” water, meaning it contains too many minerals, which end up burdening the skin or aggravating skin alterations.
In many locations, the water also has a high content of chlorine, which ends up on your skin and in the pores, which is detrimental if repeated multiple times per day.
Most water filters remove minerals, chlorine, and other substances from the tap water, which greatly improves the water quality and protects your skin in the long run. Mineral or bottled water is also a good alternative.
