Liquorice is commonly known as the pungent candy that everyone loved (or hated) as kids. It is a herb that grows in parts of Europe and Asia, and has been used as a sweetener and medicinal treatment across the globe for a long time.
In the skincare world, liquorice is known for its skin brightening and soothing benefits for dull skin. One popular use of liquorice extract is to treat dark spots, whether it is from sun damage, hormonal conditions such as melasma, or hyperpigmentation from acne scars. While hydroquinone is commonly known as the dermatologists’ favourite ingredient to fade dark spots, it unfortunately has numerous side effect due to its highly potent ingredient.

What are the components in Liquorice Extract that benefits the skin?
Liquorice’s excellent skin brightening effects comes from a compound called “glabridin”. This has properties like natural oestrogen, which helps to helps to fade hyper-pigmentation and sun damage, such as dark spots. Glabridin blocks the production of melanin which prevents hyperpigmentation from forming in the first place. Moreover, glabridin also has the ability to moisturise and keep skin smooth.
The second component found in Liquorice is “Liquirtin”, which helps in the treatment of melаѕmа. Melasma can be quite tricky to get rid of, and is more commonly seen in women with hormonal conditions, such as those who are pregnant, taking contraceptive pill or those who are exposed to intense sunlight without sun protection.
Benefits of Liquorice for the skin
- #1 Prevent skin discoloration by minimizing the production of tyrosinase: Tyrosinase is a group of enzymes that contributes to your skin's pigmentation process, which help the body produce melanin and protects skin against UV damage. Liquorice extract blocks the production of tyrosinase, which in turn prevent the production of dark spots.
- #2 Removes and dissolves melanin: The component “Liquiritin” found in Liquorice extract act as an active compound that helps to dissolve and remove existing melanin in the skin, which in turn help prevent new spots from forming and also fade existing ones.
- #3 A powerful antioxidant and anti-inflammatory benefits: It carries “Glycyrrhizin”, an acid that makes liquorice taste sweet. Glycyrrhizin is an antioxidant that protects the skin from free radicals, as well as an anti-inflammatory component which help sooth redness and irritation on the skin.
- #4 A UV-fighting super ingredient: One of the most active components found in liquorice extract – “Glabridin”, has proven to help diminish any dark spots formed due to scarring or sun damage. It also prevents pigmentation from UVB rays by inhibiting tyrosinase, an enzyme that causes dark pigments after sun exposure.
