Sodium Pyruvate
What is Sodium Pyruvate?
Sodium pyruvate is the sodium salt of pyruvic acid, a simple alpha-keto acid central to human cellular metabolism as part of the energy-producing Krebs cycle. In cosmetics, it acts as a skin conditioning agent, commonly found in moisturizers, lotions, and serums designed for daily use. It works by drawing moisture to the skin's surface and aiding in moisture retention, which supports the skin's natural suppleness and barrier function. Unlike its acidic parent compound used in peels, this salt form is milder and integrates well into leave-on products. Synthetically produced for consistency and purity, it provides a straightforward way to enhance skin feel without aggressive effects, making it suitable for routine skincare routines focused on maintenance.
