What Is Glycyrrhiza Glabra Rhizome/Root?

Glycyrrhiza glabra rhizome/root, commonly known as liquorice root, is an extract derived from the underground stem and root system of the liquorice plant. It contains a range of bioactive compounds including glabridin and liquiritin, which are responsible for many of its skincare properties.

In cosmetic formulations, liquorice root extract functions primarily as an emollient and humectant, helping to hydrate and soften the skin. It is also recognised for its soothing properties, which may help calm irritated or reactive skin.

How It Works

Liquorice root extract works through multiple mechanisms. Its humectant properties allow it to absorb and bind water to the skin, enhancing hydration from within. The active compounds, particularly glabridin, are thought to have anti-inflammatory effects that help calm irritated skin and reduce redness.

Research into its effects on hyperpigmentation is still emerging, with some studies suggesting that certain fractions of the extract may influence melanin production, though the clinical significance in topical skincare products requires further investigation.

Clinical Evidence & References

Research supports liquorice root extract's role in wound healing and skin hydration. Studies using hydrogel formulations containing the extract have shown promising results in promoting skin regeneration in burn models, with topical application demonstrating effects on wound closure and transepidermal water loss.

Evidence for its use in treating hyperpigmentation is less established. Whilst some research has investigated concentrated fractions of the extract using advanced delivery systems, the translation of these findings to conventional skincare products remains unclear. Its soothing and moisturising benefits are better supported by existing data.

How to Use

Liquorice root extract is typically incorporated into serums, creams, and hydrating masks. As it is generally a supportive ingredient rather than a primary active, it works well alongside other skincare components. There is no specific upper limit on frequency of use; products containing this ingredient can usually be incorporated into both morning and evening routines as part of your regular skincare regimen.

Safety & Precautions

Liquorice root extract is generally well-tolerated by most skin types. Those with a known allergy to liquorice or members of the Fabaceae family should avoid products containing this ingredient.
