Ingredient Info

Sodium PCA is a natural humectant—a moisture-binding ingredient derived from pyrrolidone carboxylic acid—that helps skin attract and retain water. It works by drawing hydration into the outer layers of skin, making it a gentle, well-tolerated moisturizing agent.



Benefits

  • Hydrates and moisturizes skin by binding water to the stratum corneum
  • Helps improve skin softness and smoothness
  • Well-tolerated by most skin types, including sensitive skin

Science: The Cosmetic Ingredient Review Expert Panel (2019) concluded that sodium PCA is safe for use in cosmetics at current concentrations and practices. Research confirms it localizes effectively in the outer skin layer where it functions as a humectant, with no significant safety concerns identified in peer-reviewed assessments.
