why we use glycyrrhiza inflata (licorice) root extract
The Basics
Glycyrrhiza inflata, commonly known as Chinese licorice, has been esteemed in traditional medicine for its therapeutic properties. The root extract is particularly valued in skincare for its high concentration of Licochalcone A, a potent flavonoid with notable anti-inflammatory and antioxidant activities.1
In Glycyrrhiza inflata, the Licochalcone A content can reach approximately 8–10 mg per gram of dry root (about 1%).2 While most licorice extracts contain only trace amounts of this compound, the extract used in Cipher products is standardised to a minimum of 20% Licochalcone A for maximum efficacy.
Skin Benefits
Licochalcone A has been shown to modulate inflammatory responses in the skin. Topical application of formulations containing Licochalcone A has demonstrated significant reductions in skin redness and irritation, underscoring its efficacy as a soothing agent.3
Beyond its anti-inflammatory effects, Licochalcone A activates antioxidant and detoxifying enzymes, providing a protective effect against oxidative stress. This action helps to shield skin cells from damage induced by environmental factors, contributing to overall skin health.4
Scalp Benefits
In scalp care, Licochalcone A's anti-inflammatory properties have been leveraged to alleviate dryness, itching, and subclinical inflammation. Clinical studies have reported that scalp tonics containing Licochalcone A effectively increase scalp moisture and reduce discomfort, promoting a healthier scalp environment.5
