RIBONIC ACID

Safety grade: A

Ribonic acid is a mild organic acid derived from ribose, a natural sugar. It helps maintain the right pH balance in skincare products and works to improve product stability.

This ingredient acts as a pH buffer to keep products at a safe level for skin and as a chelating agent that binds to metals, preventing them from causing product deterioration or irritation.
