What is pH/LOCK™?

Your sensitive skin's new BFF: pH/LOCK™

We developed pH/LOCK™ to respond to one of the reasons why sensitive skin is so, well, sensitive: an off-balance pH level.

So what exactly is pH/LOCK? This proprietary blend of powerful-yet-gentle ingredients sets and maintains an optimal pH of 4.7 for 12+ hours, offering protection against environmental stressors, while stimulating skin repair and renewal.

To fully appreciate pH/LOCK™, we need to talk about your skin

The biggest organ in your body is your skin — and it does a lot more than just look pretty. Your skin is the first defense against environmental stressors such as UV, pollution, allergens, and microbes. But, skin is more than just a physical barrier. It’s a complex ecosystem composed of: the physical barrier, the acid mantle, and the microbiome.

These three components work together as an all-for-one, one-for-all kind of deal. An imbalance in any one of them affects the other two. So when the skin barrier isn’t working well, microbes and other irritants see it as an invitation, resulting in some pretty unhappy skin. And your skin will show how upset it is with dryness, flakiness, eczema, acne and other annoying skin conditions.

Unlike most skincare, which only focus on the physical skin barrier, pH/LOCK™ improves all three pillars of skin health, bringing much-needed balance to your skin.

Why is skin pH important?

Healthy skin depends on maintaining the perfect pH level. With a scale of 1-14, with lower numbers being more acidic and higher numbers being more alkaline, the perfect pH level for skin is 4.7—a bit more on the acidic side. But plenty of things can disrupt the pH level, weakening the skin barrier and allowing nasties like pathogenic microbes under the surface. People with eczema have an elevated pH level, which leaves their skin surface even more vulnerable to pathogens, causing irritation and flare-ups.

The problem with other "pH-balanced" skincare

In a recent study*, researchers took a look at 58 mainstream products that claim to protect the skin barrier. Instead, they found that most of those products were too high in pH and were more likely to negatively impact acid mantle and microbiota systems. That means that many common products actually can irritate your skin—despite the marketing promises.

The magic of pH/LOCK™

As mentioned, showering can cause havok on the skin’s pH levels. So what can we do about this constantly fluctuating pH level? That’s exactly where pH/LOCK™ comes in.

By maintaining an optimal pH of 4.7 for 12+ hours, Soteri products protect your skin against environmental stressors while stimulating barrier repair, strengthening the acid mantle, and restoring the microbiome. No skin component left behind!
