Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A water-soluble salt derived from glycyrrhizic acid, which is extracted from the root of the licorice plant (Glycyrrhiza glabra). It is purified and stabilized for use in cosmetics.
How it works
It inhibits enzymes that trigger inflammation (like cyclooxygenase and lipoxygenase) and reduces the release of pro-inflammatory compounds. This calms redness, swelling, and irritation. It also has mild antioxidant properties and can inhibit tyrosinase, an enzyme involved in melanin production, which may help with hyperpigmentation.
Pros
Calms redness quickly
Tripotassium Glycyrrhizate works by inhibiting inflammatory enzymes, so it can visibly reduce redness and irritation soon after application, making it great for reactive skin.
Very low irritation risk
Unlike some active ingredients that can sting or burn, this ingredient is extremely gentle and well-tolerated, even on compromised or post-procedure skin.
Cons and cautions
Mild brightening effect only
While it can help fade dark spots, its effect on hyperpigmentation is subtle compared to stronger ingredients like hydroquinone or kojic acid. It works best as a supporting ingredient.
Limited standalone potency
For significant inflammation or pigmentation issues, Tripotassium Glycyrrhizate is usually combined with other soothing or brightening agents rather than used alone.
Best for
- People with sensitive, easily irritated skin
- Those dealing with redness, rosacea, or post-inflammatory hyperpigmentation
Use caution if
- Individuals with a known allergy to licorice or related plants
Usage tips
Safety summary
Tripotassium Glycyrrhizate is considered very safe for topical use. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in cosmetic concentrations. Allergic reactions are rare but possible in individuals sensitive to licorice.
Research notes
Multiple in vitro and small clinical studies support its anti-inflammatory and skin-lightening effects. However, large-scale human trials are limited. It is well-established as a soothing agent in dermatology and cosmetic science.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Generally recognized as safe at typical use levels.
- Common uses
- Serums, Moisturizers, Toner, Masks, Post-procedure creams
- Environmental note
- Derived from licorice root, which is a renewable plant source. However, overharvesting of wild licorice can be an ecological concern; look for sustainably sourced ingredients.
Good to know
- Tripotassium Glycyrrhizate is water-soluble, so it works well in gel-based or lightweight formulas.
- It is often used in post-procedure skincare because it is non-irritating and helps reduce recovery redness.
