pH Balance of your skin
First thing first: Let’s break down the science of it. The pH scale runs from 0 (acidic) to 14 (basic). Healthy skin has a natural pH level of 5.5, so your skin is slightly acidic and performs its best within that narrow, ideal environment, our goal is to keep it that way. The acid mantle is an effective form of protection, but if your pH level is too alkaline or too acidic, the mantle is disturbed and results in skin issues like dermatitis, eczema , and rosacea.
High pH (8 to 14)
Products with a high pH level i.e. alkaline (most soap bars) pose the biggest threat. That tight, squeaky-clean feeling you might get after washing your face is a sign of high pH cleanser and damaged skin barrier, and to help remedy the situation, you have to reach for a toner to “balance your skin.”
Low pH (1 to 6)
Generally, lower ph is kinder on skin. But, too low of a pH can irritate it. At-home peels and AHA/BHA products tend to have a lower pH, making them great exfoliants but just as stripping. Hence, look for such exfolianting products with ingredients that restore moisture in skin.
Everything on your skin should be pH balanced. Your cleanser, your serum and moisturizer should be balanced, your makeup and sunscreen should be balanced. You want to look for skin-care products with a pH of 5.5. If anything, they could be as low as 4.5 and as high as 7. Stick to this range religiously. If you are unsure of what exactly the pH of your favorite skin-care product is, you can check by pH-testing them with litmus paper.
Keep up the Balancing Act!
