The Hydrating Toner by California Biology is a lightweight yet deeply nourishing treatment designed to replenish moisture, rebalance the skin, and enhance overall clarity. Inspired by K-beauty skincare philosophy, this toner focuses on layering hydration and restoring comfort immediately after cleansing, leaving the skin refreshed and perfectly prepped for serums and treatments. Its silky texture absorbs quickly, making it ideal for professional protocols or daily home use.
 
Formulated to support optimal hydration levels, the toner helps soothe the skin, refine texture, and promote a smooth, healthy looking complexion. With consistent use, skin feels soft, balanced, and visibly more radiant while maintaining long lasting moisture and resilience.
