Wellness Wednesday: the quiet importance of your skin’s pH
Healthy skin sits at a pH of around 4.7 to 5.5. Slightly acidic, which sounds counterintuitive until you understand what that acidity actually does.
That thin acidic film on the surface of your skin has a name: the acid mantle. It is made of sebum, sweat, and amino acids, and it does three quiet jobs. It keeps your skin’s resident bacteria in a balanced range. It supports the enzymes that knit ceramides into the skin barrier. And it discourages the kinds of microbes that prefer alkaline territory.
Why most bar soaps work against this
Conventional bar soaps run a pH of around 9 to 10. That is alkaline enough to disrupt the acid mantle for hours after washing, sometimes longer if the barrier is already a little fragile. It is also why people who switch from a high-pH cleanser to something gentler often notice that tightness, that papery feeling after the shower, simply stops happening.
A pH-balanced liquid cleanser sits closer to skin’s own range, somewhere between 4.5 and 6. Most thoughtfully made natural cleansers are formulated this way, ours included. It is one of the quieter signals of a well-built product, the kind of detail you only notice by its absence: the absence of dryness, the absence of that pulled-tight feeling.
A small test you can run on yourself
If your skin feels tight after washing, that is information. The cleanser is taking more than it should. A pH-appropriate face wash, or even a plain water rinse in the morning, gives the acid mantle the space to do its work. Many people find that the most flattering thing they can do for their skin is wash it a little less, with a little more care.
The calm feeling skin has when it is left mostly alone is rarely an accident. It is, more often, the result of small choices like this one.
