Licorice Root for Brighter-Looking Skin: How It Works

Yes, licorice root extract can help skin look brighter and more even in tone. It comes from the Glycyrrhiza glabra plant, and its best-known active, glabridin, is an antioxidant that calms the look of dull, uneven patches. It works slowly and gently, so it suits people who find stronger brighteners a bit much.

What is licorice root extract in skincare?

Licorice root extract is a plant extract used across Korean skincare for a soft, glowing finish. You will see it on labels as licorice root extract, Glycyrrhiza glabra root extract, or glabridin, which is the purified active. It shows up in serums, ampoules, and toners, usually sitting alongside other gentle brighteners rather than doing all the work on its own.

How licorice root helps skin look brighter

Two things are going on. First, glabridin is an antioxidant, so it helps defend the skin surface from the daily stress that leaves skin looking grey and tired. Second, it gently slows the step that makes extra surface pigment show up, which softens the look of dark spots over time.

Lab work backs both effects: one paper measured its antioxidant and pigment-calming activity, and further research on glabridin and skin tone points the same way. What you notice is a more even, lit-from-within look, not a sudden switch.

Here is the part worth picturing. Deep in your skin sit tiny pigment factories, and each one runs on one key worker, an enzyme called tyrosinase. Think of it as the foreman on a production line.

Every time strong sun or daily stress hits, the foreman speeds up and stamps out more pigment, which then rises to the surface as those darker, patchy spots. Glabridin, the active in licorice root, works like a hand on the foreman’s shoulder, quietly getting him to slow down so fewer new pigment specks are made.

Its antioxidant side helps here too. Sun and pollution throw off tiny sparks, called free radicals, that keep poking that foreman to work faster. Glabridin soaks up a good share of those sparks, so the pigment line stays calmer.

That is why the change looks slow and even instead of sudden. You are not scrubbing pigment away, you are gently turning down how much gets made in the first place.

How to use licorice root extract

• Cleanse, then apply a licorice or brightening serum to clean, slightly damp skin.
• Use it once or twice a day.Morning pairs well with sunscreen, since sun exposure is the main reason tone looks uneven in the first place.
• Give it time.Most people see a softer, more even look after four to eight weeks of steady use.
• Always finish your morning routine with SPF.Brighteners do their best work when skin is protected during the day.

What to pair it with

Licorice root is easy to layer.

It sits nicely next to niacinamide, another gentle brightener that also supports an even tone, so the two are a common pairing in Korean routines.If your skin runs sensitive or looks a little red, follow with a calming step like centella to keep things comfortable. If you would rather grab a ready-made option, a Korean brightening serum, like this licorice glow serum, gives you a simple one-step version.

What results look like

Licorice root is a slow, steady ingredient.

In the first few weeks skin often just looks a bit fresher and less dull.Over a couple of months, dark spots and patchy areas tend to look softer and more blended into the skin around them.It will not change anything overnight, and it is gentler than acids or high-strength actives, which is exactly why so many people reach for it.

Is it gentle on skin?

Licorice root extract is one of the milder brighteners, and most skin types get on with it well, including sensitive and reactive skin.

As with any new product, patch test first: dab a little on your inner arm for a couple of days before using it on your face. If you use prescription products or have very reactive skin, have a quick word with your pharmacist or doctor before adding anything new.
