What Is pH Color-Changing Makeup?
Also known as “pH-matching” or “color-adaptive” makeup, this trend refers to products that shift color upon contact with your skin, reacting to its unique pH level, resulting in a truly one-of-a-kind shade.
The Science Behind the Glow
-
pH in your skin: Human skin is slightly acidic, usually between pH 4.5–5.5, but this varies by person and even changes during the day.
-
Activation by skin chemistry: Color-changing formulas feature special dyes such as Red 27 and Red 21. These are typically colorless (or neutral) in the product but become vibrant—often pink or rosy—when they come into contact with the moisture and acidity of your skin.
-
Personalized effect: Because everyone’s pH is slightly different, the result is a shade uniquely tailored to you. The final color depends on both your skin’s acidity and its natural tone.
