What Is (Licorice/Reynoutria Japonica) Root/Stem Extract?

Licorice root extract (also known as Reynoutria japonica root/stem extract) is derived from the licorice plant and contains several bioactive compounds, including flavonoids and polyphenols. These components give the extract its primary function as an antioxidant in skincare formulations.

As an antioxidant, this ingredient works to neutralise free radicals — unstable molecules generated by UV exposure, pollution, and other environmental factors that can damage skin cells over time.

Benefits for Your Skin

How It Works

The extract contains polyphenolic compounds that act as antioxidants by donating electrons to free radicals, stabilising them and preventing them from causing cellular damage. This process helps reduce oxidative stress, which contributes to visible signs of ageing and skin irritation.

The ingredient also has mild anti-inflammatory properties, which may contribute to a calming effect on reactive or stressed skin.

Clinical Evidence & References

Licorice extract has been studied for its antioxidant and anti-inflammatory potential in skincare. Research suggests it can help protect skin from oxidative damage and may support skin barrier function, though the scale and scope of clinical studies remain limited compared to some other antioxidants.

Evidence is strongest for its antioxidant capacity in vitro, with some in vivo studies showing mild anti-inflammatory benefits. More robust clinical trials would help clarify its effectiveness at typical cosmetic concentrations.

How to Use

Licorice extract is typically found in serums, moisturisers, and treatment products at varying concentrations. It works well alongside other antioxidants and is generally compatible with most skincare ingredients. Use consistently as part of your daily routine to support cumulative antioxidant protection, particularly if your skin is exposed to environmental stressors or you are concerned about premature ageing.

Safety & Precautions

Licorice extract is generally well-tolerated by most skin types. Those with known sensitivity to licorice or related plants should patch test first.
