What Is Licorice Root Extract?
Licorice root extract is derived from the Glycyrrhiza glabra plant and is one of the most effective natural brightening ingredients available. Its key active compounds include glabridin and liquiritin, which inhibit tyrosinase activity to reduce melanin production.
Unlike some brightening agents that can be harsh or irritating, licorice root extract is gentle and has soothing, anti-inflammatory properties. This makes it an excellent choice for sensitive skin or those who cannot tolerate hydroquinone.
In addition to its brightening effects, licorice root extract provides antioxidant protection and helps calm redness and irritation. It can help address various forms of hyperpigmentation including sun spots, melasma, and post-inflammatory marks.
Licorice root extract works well in combination with other brightening ingredients like niacinamide, vitamin C, and arbutin for enhanced results. Consistent use over several weeks is needed for visible improvement.
Clinical Evidence & References
Licorice root extract has accumulated a reasonable body of clinical evidence supporting its use as a skin-brightening and anti-inflammatory agent. Its primary active compounds—glabridin and liquiritin—work by inhibiting tyrosinase, the enzyme responsible for melanin synthesis. Studies demonstrate efficacy against hyperpigmentation including melasma and post-inflammatory marks, with the additional benefit of antioxidant and soothing properties that make it suitable for sensitive or irritation-prone skin.
Whilst the evidence base is solid, some limitations warrant consideration. Most published studies involve relatively small sample sizes, and visible results typically require consistent use over several weeks to months. Individual responses vary, particularly depending on skin tone, pigmentation type, and concurrent skincare regimen. Licorice root extract is generally well tolerated, though those with licorice sensitivity should exercise caution. Further large-scale, longer-term trials would help clarify optimal concentrations and timeframes for clinical benefit.
