If you have ever heard any commercial on TV for a skin care product, then you have heard of “pH” before. So many advertisements claim “restore pH”, or “pH balanced” on their brands. What does that really mean, though? Im going to take you back to high school science class on this blog post…but you may want to LISTEN UP if you love your skin at all!
Back to the Basics:
The pH (potential hydrogen) of a substance is its degree of acidity or alkalinity, and is measured on a scale of 0 to 14. Acids or substances that have a pH below 7.0, and Alkalis have a pH above 7.0. So, the higher the pH number, the greater the alkalinity. NEUTRAL on the scale is a 7.0 as well. Every number change on the scale represents a tenfold change, and is 10 times different than the number before or after. As a point of reference, your skin and hair are approximately a 5.0 on the pH scale. This happens in the acid mantle, which is where your sweat and oil are purposely produced to create a safe barrier for the skin, protecting it from outside elements.
