Licorice Root Benefits for Skin

Some love it, and others not so much! That black bitter and odd tasting candy, licorice. Also called anise, licorice extract finds a home in some kitchens alongside other baking extracts such as vanilla and peppermint. Not as well-known as its sweet taste are the syrupy liquid's medicinal properties, including its ability to promote healthy, even-toned skin as an ingredient in personal care products. Now who knew that there was such a worthy related benefit from licorice root?

Licorice root has a good reputation as being helpful for sensitive skin. Licorice root contains an active compound called “glabridin.” Licorice extract may also help diminish the appearance of dark under-eye circles, discoloration and age spots. The extract also has powerful antioxidants that help protect the skin from environmental stressors, as well as “licochalcone,” which helps balance oil, making this a good ingredient for those with oily skin.


Getting to the Root of Things

Licorice is the root of a plant called Glycyrrhiza glabra, a legume related to beans and peas that is native to southern Europe and parts of Asia. It likes well-drained soils with full sun and is harvested about two-three years after planting. This plant is a perennial, and it grows to 3-7 feet high, with feather-like leaves 3-6 inches long and purple to pale whitish blue flowers. The fruit is small and only about 1 inch long, with several seeds inside.

The root is what's typically used for both its health benefits and skin care benefits. The extract is produced by boiling the root, evaporating most of the water, and saving the remaining syrup. A compound in the syrup called “glycyrrhizin” is a sweetener considered to be much sweeter than sucrose, which also has health benefits.

Licorice extract has been used for its health benefits as far back as ancient China, and it is an ingredient in some over-the-counter cleansers, toners, face creams and spot treatments. The syrupy juice from the herb's root contains beneficial plant sterols, which promote skin elasticity and fight inflammation and wrinkle formation. Licorice extract also contains glycyrrhizin, an acid that plays a role in increasing steroid hormones that naturally occur in skin. Glycyrrhizin helps to combat several skin disorders that respond to topically applied hydrocortisone. Licorice extract also can help soothe irritation caused by some skin-care products and medications.

Healing Troubled Skin

Body cleansers, body creams and facial skin-care products that incorporate licorice extract have effectively treated skin disorders such as rosacea, eczema, psoriasis and dermatitis. Licorice extract is anti-inflammatory. Inflammation is the body's natural attempt to protect itself by expelling infection and irritants from the body, and it shows up on skin in symptoms such as redness, rashes, itching and swelling. Licorice extract effectively addresses these conditions in concentrations as low as 1 to 2 percent.

Fading Dark Spots

Consistent use of licorice extract over time has been known to fade dark spots and blemishes and lighten skin. It can also reverse darkening of scars, which are fibrous skin tissues that remain when an injury hasn't completely healed. Licorice extract is also a good natural substitute for hydroquinone, which causes adverse reactions in some users. An ingredient called glabridin helps reduce uneven skin darkening, also known as hyper pigmentation, caused by exposure to the sun's ultraviolet rays. Glabridin is an active ingredient containing five flavonoids that act to depigment, or lighten, skin while blocking an enzyme that causes damaged skin to darken.

Preventing Skin Problems

Potent antioxidants in licorice extract fight skin-damaging free radicals. Licochalcone, another ingredient in licorice, helps to regulate the skin's oil production, making it useful in anti-acne skin-care regimens, as some zit outbreaks are the result of pores being clogged by overly active oil glands. Although licorice extract has many benefits, there are some cautions. Avoid product contact with the eye area, and when checking product labels, remember that licorice extract might be listed as dipotassium glycyrrhizate.
