Licorice Root for Dark Spots: 2026 Skincare Truths

There’s so much bad information floating around about skin issues, especially the dark spots from post-inflammatory hyperpigmentation (PIH) that often pop up after waxing. It’s hard to tell what actually works from what’s just an urban legend. Licorice root extract is a really promising natural option, but a lot of people don’t understand what it can and can’t do.

Myth 1: Licorice Root Extract Is a Quick Fix for Dark Spots

The thought that some natural ingredient can just wipe away years of sun damage or the brown marks from a breakout or wax is nice, but it’s a total misconception. Brands love to promise fast results, making people think a couple of uses of something like licorice root extract will magically fix their skin. That’s not how skin works. Our skin’s cell turnover cycle, the whole process of new cells replacing old ones, takes time. In adults, that’s typically 28 to 40 days, and it gets even slower as we age. To fix hyperpigmentation, you have to work *with* that cycle by slowing down melanin production and helping those pigmented cells shed faster.

Licorice root extract comes from the Glycyrrhiza glabra plant and its power is in compounds like glabridin and liquiritin. Glabridin’s job is to inhibit tyrosinase, which is a key enzyme for making melanin. Liquiritin then comes in to help break up the melanin that’s already there and speed up its removal. They’re a great team, but they need you to be consistent. Research in the Journal of Clinical and Aesthetic Dermatology shows that you typically won’t see visible improvement from topical treatments for at least 8 to 12 weeks. Expecting clear skin in a few days is setting yourself up for disappointment. You have to be patient and stick to a daily routine. If you skip days or quit after a week, you’ll never see what it can really do.

Myth 2: All Licorice Root Products Are Equally Effective

Seeing “licorice root extract” on a label does not mean the product will actually work. This is a huge myth in skincare generally, but it’s especially a problem with active ingredients. The real-world effectiveness of a botanical extract depends on a few things: which part of the plant they used, how they extracted it, the final concentration of the active compounds, and the product’s overall formula. A serum might have a tiny, useless amount of the extract, or the extract itself might be poor quality and missing the stuff that does the work.

For licorice root extract to do anything for hyperpigmentation, it must have enough glabridin and liquiritin. The problem is, most cosmetic companies don’t tell you the concentration of these actives. So what should you look for? Seek out products from brands that are transparent and mention standardized extracts or the actual percentage, like a formula “containing 0.5% glabridin.” If you don’t have that info, you’re just guessing. The American Academy of Dermatology often stresses that ingredient quality and concentration are what determine success. A product from a brand that invests in formulation science is a much safer bet than whatever is cheapest. My advice is to ignore the hype and actually read the label and company info.

Myth 3: Licorice Root Extract Works Best on Its Own

Licorice root extract is a fantastic ingredient for tackling post-wax dark spots and other types of hyperpigmentation, but it’s not a solo act. The best skincare results almost always come from a synergistic approach, where different ingredients work together to hit a problem from multiple angles. It’s just smart strategy.

To really make a dent in hyperpigmentation, you can get much better results by combining licorice root with other well-studied ingredients. For instance, niacinamide (Vitamin B3) is great for calming inflammation and strengthening the skin barrier, which helps reduce pigmentation. Vitamin C is a strong antioxidant that also inhibits tyrosinase and generally brightens up the skin. Then you have things like alpha hydroxy acids (AHAs), such as glycolic acid, which speed up exfoliation to get rid of pigmented cells faster. Newer ingredients like tranexamic acid are also getting attention for interrupting melanin pathways. A review in the Journal of the American Academy of Dermatology confirms that for tough cases of hyperpigmentation, combination therapies work far better than using a single ingredient. This doesn’t mean you need a crazy 10-step routine, but adding one or two smart, complementary ingredients will absolutely speed things up. It’s about using a well-formulated product, not just throwing more things at your face.

Myth 4: Sun Protection Isn’t as Important if You’re Using Licorice Root Extract

This idea is completely wrong and will sabotage any progress you make on hyperpigmentation. People sometimes think that because they’re using an active ingredient like licorice root extract to fade spots, they can ease up on sunscreen. That’s the exact opposite of what you should do. The sun is the number one trigger for melanin production and the main reason you have dark spots in the first place. Even a little bit of unprotected sun exposure can undo months of hard work.

When UV radiation hits your skin, your melanocytes (the melanin-making cells) panic and go into overdrive to protect you. This makes new spots and darkens the ones you already have. Licorice root extract helps put the brakes on that process, but it’s no match for direct UV rays. The Skin Cancer Foundation is clear that daily, year-round sun protection is the single most important thing for managing skin discoloration. That means a broad-spectrum sunscreen with SPF 30 or higher, every single day, rain or shine, even if you’re inside near a window. You also have to reapply it every two hours if you’re outside or sweating. Without that diligence, you’re just spinning your wheels, trying to treat the problem while constantly making it worse.

Myth 5: Licorice Root Extract is Only for Facial Hyperpigmentation

It’s easy to get tunnel vision on facial skincare, since that’s what we see in the mirror every day. But thinking that licorice root extract only works for facial hyperpigmentation like post-wax dark spots on the upper lip is a mistake. Hyperpigmentation can show up anywhere you have inflammation, friction, or sun damage. I see it all the time on the underarms, bikini line, inner thighs, back, and chest.

The way licorice root extract works, by inhibiting tyrosinase and dispersing melanin, is the same no matter where you apply it. Its function isn’t specific to facial skin. Lots of clients get PIH on their legs after waxing or dark patches under their arms from shaving and friction. A body lotion or serum with licorice root extract can be a huge help in those areas. For example, a client who gets redness after a leg wax could use a cream with licorice root to calm the inflammation and prevent those red marks from turning into long-lasting brown spots. The key is the same as for your face: apply it consistently to the areas you’re treating. If you have dark spots on your body, give licorice root a try there too.

To get a handle on hyperpigmentation, especially those stubborn post-wax dark spots, you need to understand what licorice root extract really does. It’s a great tool, but it’s not magic. It demands patience, smart product selection, and a commitment to overall skin health.
