It promotes blood circulation
With carbon dioxide working its magic, this brings blood and oxygen to your skin, creating the appearance of healthier-looking skin. At room temperature, sparkling water can trigger your blood vessels to open up. It then boosts the supply of nutrients brought to your skin. With this better circulation, your system also improves and your skin looks better. It also leaves a subtle flush — no need to add more blush later on.
It has the same pH balance as your skin
Aside from this, sparkling water also has the same pH as your skin (it has a pH of 5.5) so it doesn’t irritate your face. Tap water is typically found to have a pH of 7, which can disrupt the skin’s acid mantle, a barrier on the skin’s outermost layer. Washing with tap water can cause dryness, creating tiny cracks in your skin where bacteria can grow and cause acne breakouts. Eep!
