Yes or no? Before we can answer, we need to understand what washing your face does. Most people know washing your face takes away makeup and impurities – but – most people don’t know washing your face also changes/teases/raises your skin pH.
pH is a measure of how acidic or how alkaline something is.
Lemons are acidic.
Spinach is alkaline.
Tap water is averagely neutral.
Mixing together liquids which have different pH levels – changes pH.
If you made lemon spinach – yummy!? – the overall pH of your meal would change.
Like adding more and more tap water to lemon juice – it gets less and less lemony, less and less stingy and less and less acidic.
pH is measured on a scale of 0 to 14.
Anything below 7 is acidic. Anything above 7 is alkaline.
Your skin also has a pH.
Psst! Most people think skin pH should be about 5.5.
In fact – an exceptionally healthy skin pH looks likely to be around pH 4 to 4.5.
…and here’s why washing your face has potential to cause acne;
- Most kinds of soap are high pH aka alkaline
- Some cleansers can be as alkaline as pH 12 (!)
- Tap water is about pH 7 and hard water is over pH 8.5
Bottom line: Acne face wash could be raising your skin pH above healthy aka causing you sudden breakouts.
