If you’ve ever searched online, most likely Pinterest, for a new/cheaper/more “natural” physical exfoliator, baking soda has probably appeared. I’ll admit I used a baking soda and water combination as a facial exfoliator for a long time. The further I looked into this combo though I discovered how harsh it was actually being towards my skin. While baking soda definitely is a cheaper and more simple exfoliator to use, the pH of the product is far too harsh for your skin’s mantle.
I decided I need to figure out exactly what this pH is. I mixed a small amount of water and baking soda together, stirred and then tested the solution with a litmus paper. The pH of this solution turned out to be ~9. This shockingly high value means that baking soda should definitely not be used on our skin.
ingredients: sodium bicarbonate
Sodium bicarbonate is a salt compound that is usually found in crystalline form, aka, baking soda. Its basic nature is way too high for our skin mantle, however, it is often used as an acidic neutralizer, which is why it’s used in baking.
So the takeaway here is to be careful if you still choose to use a baking soda and water solution as an exfoliator. However, there are plenty of other physical exfoliator options out there for you to try out that will be pH safe for your skin!
