Have you ever read, "PH BALANCED" on a product and wondered what it meant?

How pH Balance Impacts Common Skin Concerns

From irritation and dryness to acne and inflammation, your skin’s pH level plays a critical role in how healthy, resilient, and comfortable your skin feels on a daily basis. When your skin’s pH is balanced and slightly acidic at around 5.5, it supports a strong protective barrier that helps retain moisture, defend against harmful bacteria, and reduce sensitivity. This balance allows the skin to heal efficiently, remain hydrated, and maintain a smooth, even appearance.

However, when the skin’s pH becomes too alkaline or overly acidic, this delicate balance is disrupted. An imbalanced pH can weaken the skin barrier, leading to increased water loss, irritation, redness, and a higher susceptibility to breakouts and infections. Acne causing bacteria thrive in higher pH environments, while dryness and flakiness often result from a compromised acid mantle that can no longer protect the skin effectively. Understanding and maintaining proper pH balance is essential for calming existing skin concerns and preventing new ones from developing.

What Is Skin pH and Why Does It Matter?

Our skin is naturally designed to fight infection and environmental stress, and its ability to do so is influenced by its pH level. Skin pH refers to how acidic or alkaline the skin is. On a scale of 1 to 14, with 1 being the most acidic and 14 the most alkaline, 7 is considered neutral.

The skin has a thin protective layer on its surface known as the acid mantle. This layer is formed by sebum, or free fatty acids, produced by the sebaceous glands, combined with lactic and amino acids from sweat. Together, these elements create the skin’s pH, which ideally remains slightly acidic at around 5.5.

The Acid Mantle: Your Skin’s Natural Defense System

Many factors can interfere with the delicate balance of the skin’s acid mantle, both externally and internally. As we age, our skin often becomes more acidic in response to lifestyle habits and environmental exposure.

How Lifestyle and Environment Disrupt Skin pH

Everything that comes into contact with the skin can impact the acid mantle. Skincare products, smoking, air quality, water, sun exposure, and pollution can all contribute to the breakdown of this protective layer, reducing the skin’s ability to defend itself effectively.

The Role of Diet in Skin pH Balance

Diet plays an important role in determining both internal and external pH levels. It is important to note that the pH of a food before digestion is not the same as its effect on the body after digestion. For example, foods that are acidic before digestion, such as lemons, become alkaline forming in the body. In contrast, many animal products that are alkaline before digestion become acid forming once metabolized.

According to dermatologist Dr. Jeannette Graf, “We need our diets to be less acidic than alkaline, otherwise internally we become too acidic.” An ideal diet includes an abundance of alkalizing foods such as leafy green vegetables, citrus fruits, tomatoes, carrots, and soybeans.

Maintaining the Acid Mantle With Optimal pH Skincare

The acid mantle is an effective form of protection, but when the skin’s pH becomes too alkaline or too acidic, this barrier is disrupted. As a result, skin conditions such as dermatitis, eczema, and rosacea may develop.

Protect and restore your skin’s pH to its ideal level of 5.5 by using a targeted skincare routine such as the 4 Step All Skin Types Set or the Acne Skin Set.
