pH and your skin: what you need to know.

Learn more about how to spot imbalances in your body and what you can do to help.

Your skin barrier is your body’s first line of defense: a microscopic shield that locks in hydration, fends off irritants, and keeps your microbiome balanced. But did you know that one of the most important factors in keeping this barrier strong and healthy is something as simple as pH?
While often overlooked, pH — the measure of how acidic or alkaline something is — plays a vital role in skin health. Products that are too harsh, too alkaline, or poorly formulated can throw your skin’s natural pH out of balance, leading to dryness, breakouts, sensitivity, and even premature aging.

Start swapping the basics: body wash

Your skin’s surface has a naturally acidic pH, typically between 4.7 and 5.75. This “acid mantle” exists to keep skin in harmony: it helps preserve moisture, regulate oil production, and maintain a healthy microbiome of good bacteria that keep harmful microbes at bay[1].
When your skin’s pH shifts too high — becoming more alkaline — it disrupts this balance. That’s when trouble starts. Alkaline skin is prone to dryness and impaired healing and inflammation, which makes it highly important to begin adding body washes that skip all those ingredients like SLS that can throw it out of balance.[2] Traditional bar soaps often have a pH of 9 or higher, which can strip skin of its protective oils and disrupt the acid mantle. [3]

Next, cleanse your skin with the good stuff

Everyone wants to feel as squeaky clean as possible, but when it comes to cleansing and exfoliating, harsh cleansers and exfoliants can hurt the skin— especially with strong acids or physical scrubs —and lead to eroding the barrier and altering pH. Choosing cleansers and other personal care products with mindful ingredients can help prevent and protect your skin from losing that precious pH balance.

Lastly, choose skincare that’s conscious

Other factors like pollution, hard water, and even UV exposure can shift skin’s pH and contribute to inflammation. The next time you’re heading out, support your skin with barrier-repairing products that have niacinamide, ceramides, and hyaluronic acid which help rebuild moisture and resilience, especially when the skin has been compromised (pro tip: whatever you add to your face, add to your neck also).

The Bottom Line

Shop for pH balanced skin and personal care products

Your skin isn’t just a surface — it’s a living, breathing barrier that needs the right conditions to thrive. By choosing pH-conscious skincare, you’re giving your skin the tools it needs to protect itself, stay hydrated, and glow naturally without harsh additives or synthetic ingredients. For healthy skin that feels as good as it looks, supporting your barrier starts with nourishing its pH.
