What Your Skin pH Means

Skin pH is dynamic, so there is no single value that is ideal for everyone.

Skin pH is dynamic and everyone’s healthy pH level varies. However, there is a healthy pH range that you want to fall into. It’s important to measure pH as an aspect of skin health, because it is a reflection of your skin’s acid mantle.

Why is that important? An intact skin barrier (AKA acid mantle) is crucial to protect your skin against bacteria, pollution and other contaminants. A healthy acid mantle pH level is near 5.5, which is slightly acidic. When pH is too high, or alkaline, the skin is left less protected to withstand irritants, which can then penetrate and damage the skin.

With the Atolla Skin Test, measuring your pH level is easy and takes less than a minute. You dip your pH strip into an activation liquid, hold it to your skin, and then receive a corresponding number that relates to the color reaction on your pH strips.

But what do those numbers really mean? We’re here to walk you through it!

If your pH level is below 4.5:

It means the acid mantle of your skin is on the acidic side, which can make you more prone to increased inflammation and significant breakouts.

If your pH level is close to 5.5:

It means the acid mantle of your skin is optimized. Congrats — this is the sweet spot!

If your pH level is above 6:

It means the acid mantle of your skin is on the alkaline side, which can make you more prone to redness and sensitivity.

Everyone is unique and has their own skin health benchmarks, so it’s important not to treat pH levels as absolute, but rather evolving. That’s why your Atolla subscription helps measure your skin levels, like pH, every month! Keep track of how your pH (and other health measurements) are changing through your Atolla profile.
