Why the pH Balance of Your Skin-Care Products Matters So Much
In high-school chemistry class, you most likely learned about pH and dipped little, color-changing strips into liquids to see where they fell on a scale of 1 to 14. In case you need a refresher: “Anything below 7 is acidic. Above 7 is alkaline, and 7 is neutral, like water,” explains cosmetic chemist Ginger King. As a high schooler on the brink of failing chemistry, all of this has a lot more to do with beauty, particularly skin care, than I ever imagined. The pH of your favorite cleanser, toner, and moisturizer affects your skin, whether you realize it or not. And chances are, it’s not for the better.
What is the typical pH of skin?
No matter which expert you ask, they’ll tell you skin rings up at a solid 5.5 on the pH scale. “Skin is an incredibly delicate organ,” says New York City-based dermatologist Rachel Nazarian. “Like every other organ in our body, skin performs its best within a narrow, ideal environment, especially when it comes to pH.” When it deviates from that magic number, harmful bacteria could grow, triggering inflammation and skin conditions, such as acne, eczema, and rosacea, she adds.
