Preservatives for Serums Containing Glycosaminoglycans

Yes, if you are mixing Glycosaminoglycans complex into a serum, you will need to add a preservative.

Serums are typically water-based formulations. Glycosaminoglycans are water-soluble ingredients. When you dissolve Glycosaminoglycans in water to create a serum, the presence of water makes the product susceptible to microbial growth (bacteria, mold, and yeast).

A preservative system is essential in any water-containing cosmetic product to prevent contamination, ensure the safety of the product during use, and maintain its shelf life.
