What Is Potassium Glycyrrhizinate?
Potassium Glycyrrhizinate is a salt derived from glycyrrhizic acid, which comes from licorice root extract. It functions as a skin conditioning agent in cosmetic formulations.
This ingredient works to improve skin texture and comfort, and is commonly used in skincare products designed to address irritation and maintain skin barrier health.
How It Works
Potassium Glycyrrhizinate is thought to work by conditioning the skin surface, helping to improve hydration and smoothness. The ingredient is derived from licorice, which has a history of use in skincare for its soothing properties.
As a salt form of glycyrrhizic acid, it is designed to be stable in formulations while delivering skin conditioning benefits.
Clinical Evidence & References
Safety assessments confirm that potassium glycyrrhizinate and related glycyrrhizic acid derivatives are well-tolerated cosmetic ingredients. Research indicates these compounds function effectively as skin conditioning agents.
Some research suggests glycyrrhizinate compounds may have anti-inflammatory properties when used in appropriate concentrations, though further clinical evidence on topical efficacy in skincare products would strengthen the evidence base.

How to Use
Potassium Glycyrrhizinate is typically used as part of a complete formulation rather than as a standalone treatment. It works well in serums, moisturisers and targeted treatments for sensitive or irritated skin. Use as directed by the product instructions, usually daily as part of your regular skincare routine.
