Skin pH Test

Welcome to Protheragen-ING's skin pH testing service! The pH of your skin is a key factor in maintaining its health and overall balance.

We offer comprehensive testing to assess your skin's pH to help formulate skin care products that are gentle, effective, and compatible with your skin's natural pH.

What Is Skin pH?

Skin surface pH is indicative of skin condition and health. Normal skin is weakly acidic and the surface pH is generally maintained at 4.5 to 6.5. Skin pH measurements can be used to assess the effect of various cosmetic products on the skin surface as well as to assess the status of acute or chronic skin diseases.

To avoid skin irritation, most cosmetic products on the market have a pH level that is consistent with the skin's physiological pH. Cleansing products may be neutral or weakly alkaline, and special care needs to be taken when applying them to avoid leaving them on the skin surface for too long.

Protheragen-ING's Skin pH Testing Service

Our services are designed to help develop products that are compatible with the skin's natural pH. By understanding your skin's pH, you can formulate gentle, effective formulations and promote a healthy skin barrier.

• Non-invasive Testing - Our testing methods are non-invasive and safe for the skin.
• Multiple Test Sites - We can perform pH testing on various areas of the skin, including the face, hands, arms, or other specific areas of interest.
• Baseline Measurements - We establish a baseline measurement of skin pH prior to the use of any product to understand the skin's natural pH and provide a reference point for any deviations.
• Product Compatibility Testing - We can perform pH testing after applying a skin care product to assess its compatibility with the skin.
• Detailed Test Report - Upon completion of the testing process, we provide a comprehensive report summarizing the methodology, pH test results and analysis.
• Expert Analysis - Our experts can provide insights into the skin's pH status, including recommendations for appropriate products or adjustments to formulations to maintain or restore the skin's pH balance.
• Customized Testing - We can provide customized testing options to meet specific requirements.

Skin pH Measurement Methods

Skin hydrogen potential (pH) is a measure of the concentration of hydrogen ions [H⁺] in a surface aqueous solution. Since skin is not an aqueous solution, and since the water-soluble components of the stratum corneum are extracted into the liquid interface between the skin and the pH measurement system, the measured skin surface pH is referred to as apparent pH.

Protheragen-ING utilizes specialized pH testing equipment to accurately measure pH. Skin apparent pH is most often measured using a skin pH meter. This instrument measures the pH of the skin based on changes in the H⁺ concentration on the skin surface.

We use two flat pH electrodes based on different electrode technologies, the Combination Flat Glass pH Electrode and the Ion Sensitive Field Effect Transistor (ISFET) pH Electrode. Apparent skin pH can be measured by applying 1 or 2 drops of deionized water or saline and placing a flat pH electrode on a wet surface.

We are happy to help you evaluate and optimize the pH compatibility of your skin care products. Please feel free to contact us to discuss your specific testing needs or for more information. We will respond within 2-4 working days.
