The Benefits of Liquorice Extract (Glycyrrhiza glabra) on the Skin

What is Liquorice Root Extract?

Liquorice root extract is derived from the Glycyrrhiza glabra plant. Known for its sweet taste, it has long been used in herbal medicine and now plays a significant role in skincare due to its skin-brightening and soothing properties. The extract is rich in bioactive compounds that help improve skin tone, reduce dark spots, and protect against environmental damage.

Benefits of Liquorice for Skin

  1. Fades Hyperpigmentation and Dark Spots

One of the most notable benefits of liquorice root extract is its ability to reduce hyperpigmentation. It inhibits the enzyme tyrosinase, which is responsible for melanin production. This helps fade dark spots, melasma, and acne scars, leading to a more even skin tone.

  1. Brightens the Skin

Liquorice is known for its skin-brightening properties. The active compounds in liquorice diminish dullness, giving the skin a natural glow. It is often included in brightening creams and serums for its ability to enhance radiance.

  1. Soothes Sensitive and Irritated Skin

Liquorice is a natural anti-inflammatory ingredient, making it ideal for people with sensitive or reactive skin. It helps reduce redness, irritation, and inflammation caused by eczema, rosacea, and acne.

  1. Protects Against Sun Damage

The antioxidants found in liquorice root help combat free radicals and oxidative stress caused by UV exposure. It also contains compounds that help repair sun damage, reducing the effects of premature ageing.

  1. Hydrates and Nourishes the Skin

Liquorice extract is rich in flavonoids and polysaccharides, which help maintain moisture in the skin. It provides hydration and helps to reinforce the skin barrier, making it beneficial for dehydrated skin types.

Active Ingredients in Liquorice Root Extract

Liquorice root extract contains several bioactive compounds that contribute to its skincare benefits. Here are the key active ingredients:

Glabridin

The primary compound responsible for reducing pigmentation

Liquorice for Sensitive Skin: Is It Safe?

Liquorice is considered one of the safest and most effective natural ingredients for sensitive skin. Unlike harsh chemical brightening agents, liquorice gently lightens pigmentation without irritating it. Its anti-inflammatory properties also make it an excellent choice for those prone to redness, rosacea, or eczema. However, performing a patch test before adding a new product to your routine is always best.

Liquorice for Skin Pigmentation: How Does It Work?

Hyperpigmentation occurs when excess melanin is produced in some skin regions, often due to sun exposure, inflammation, or hormonal changes. Liquorice root extract helps correct pigmentation in several ways:

  • Liquorice inhibits Tyrosinase Activity, the enzyme responsible for melanin production. It reduces its activity, preventing dark spots from forming.
  • Melanin Dispersal: Liquiritin helps break down and disperse existing melanin deposits, allowing them to fade over time.
  • Anti-Inflammatory Action: Since inflammation can trigger hyperpigmentation, liquorice’s soothing properties help reduce the likelihood of post-inflammatory hyperpigmentation (PIH).
  • Antioxidant Protection: Free radicals from UV rays and pollution can exacerbate pigmentation issues. Liquorice neutralises these harmful molecules, preventing further skin damage.

Using Liquorice for Sun Damage

Excessive sun exposure accelerates skin ageing, causes dark spots, and leads to uneven skin tone. Liquorice extract is an excellent natural remedy for sun-damaged skin because it:

  • Reduces UV-induced Pigmentation – Helps lighten sun spots and uneven skin tone caused by sun exposure.
  • Provides Antioxidant Protection – Shields skin from environmental stressors.
  • Supports Skin Repair – Encourages healing of sunburnt or damaged skin.

Use liquorice-infused skincare products and broad-spectrum sunscreen to protect your skin from further damage for best results.

Are There Any Side Effects of Liquorice Uses for Skin?

Liquorice extract is generally safe for all skin types, but it’s essential to use it correctly. Here are some potential side effects to be aware of:

  • Mild Sensitivity: Some individuals with extremely sensitive skin may experience slight irritation or redness.
  • Overuse Can Lead to Dryness: Since liquorice has astringent properties, excessive use may cause dryness. Always follow up with a good moisturiser.
  • Allergic Reactions (Rare): Some individuals may develop an allergic reaction in rare cases. Always perform a patch test before applying liquorice-based products to your face.
