ALGIN

Safety grade: A

Algin is a natural thickening ingredient extracted from brown seaweed that helps create a smooth, gel-like texture in cosmetic products. It's commonly used in skincare formulas to improve consistency and spreadability.

Algin thickens products to create the right texture, helps ingredients blend smoothly, and can form a protective layer on skin to lock in moisture.
