What it is

Licorice root juice is the raw liquid obtained by pressing the roots of the Glycyrrhiza glabra plant. It contains active compounds like glabridin and glycyrrhizin, which are known for their anti-inflammatory and antioxidant properties.

How it works

In a cosmetic product, licorice root juice helps calm irritated skin by reducing the activity of enzymes that cause inflammation. It also inhibits the enzyme tyrosinase, which is involved in melanin production, helping to fade dark spots and even out skin tone over time.

Pros

Gentle on sensitive skin

Licorice root juice is naturally soothing and rarely causes irritation, making it a good choice for those with reactive or redness-prone skin.

Helps even skin tone

By gently inhibiting melanin production, it can gradually reduce the appearance of dark spots and hyperpigmentation without harsh bleaching.

Cons and cautions

Slow results

Compared to stronger brighteners like vitamin C or prescription treatments, licorice root juice works more subtly and may take weeks to show visible improvement.

Effectiveness depends on formulation

The concentration and stability of the juice in a product can vary, so not all products with this ingredient will deliver the same benefits.

Best for

  • People with sensitive or redness-prone skin
  • Those looking to gently brighten dark spots or post-acne marks

Use caution if

  • Individuals with a known allergy to licorice or plants in the Fabaceae family

Usage tips

Use consistently for at least 4–6 weeks to see gradual brightening effects.
Pair with a broad-spectrum sunscreen during the day to protect skin and enhance brightening results.
Apply after cleansing and before heavier creams for best absorption.

Safety summary

Licorice root juice is considered very safe for topical use with a low risk of irritation or allergic reaction. It is non-comedogenic and suitable for most skin types, including sensitive skin.

Research notes

Studies support the anti-inflammatory and tyrosinase-inhibiting effects of licorice root compounds, particularly glabridin. However, most research is on isolated compounds rather than the whole juice, and more human trials are needed to confirm efficacy in cosmetic formulations.
