Ingredient review
Stearyl Glycyrrhetinate
INCI: Stearyl Glycyrrhetinate
A gentle, oil-friendly licorice derivative that helps calm redness and soothe sensitive skin without irritation.
In plain English
Stearyl glycyrrhetinate is a modified version of a compound found in licorice root. It is oil-soluble, which means it mixes well into creams and lotions rather than water-based products. In skincare, it works to calm down irritated or red skin by reducing the activity of certain inflammatory signals. It is not a cure for any skin condition, but it can be a helpful addition to a routine focused on soothing sensitivity or supporting an even-looking complexion.

Quick decision guide
Useful, but context matters
Stearyl Glycyrrhetinate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Stearyl Glycyrrhetinate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
Stearyl glycyrrhetinate is the stearyl alcohol ester of glycyrrhetinic acid, a triterpenoid compound naturally found in licorice root (Glycyrrhiza glabra). This chemical modification makes it more stable and oil-soluble, allowing it to be easily incorporated into oil-phase formulations like creams, balms, and serums.
How it works
It works primarily by inhibiting enzymes involved in the inflammatory cascade, such as 11β-hydroxysteroid dehydrogenase and phospholipase A2. By reducing the production of pro-inflammatory mediators, it helps calm redness, swelling, and irritation when applied topically. It also has some antioxidant properties that can help protect skin from environmental stressors.
Pros
Gentle soothing action
Helps calm redness and irritation without causing stinging or burning, making it suitable for sensitive skin types.
Oil-soluble versatility
Unlike water-soluble licorice extracts, this form blends easily into creams, balms, and oil-based serums, expanding formulation options.
Cons and cautions
Modest evidence base
Most research focuses on the parent compound glycyrrhetinic acid; fewer studies specifically evaluate stearyl glycyrrhetinate in cosmetic use.
Potential for lower potency
The ester modification may reduce its bioavailability compared to the free acid form, possibly requiring higher concentrations for similar effects.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle soothing ingredient in moisturizers or serums
Use caution if
- Individuals with a known allergy to licorice or related plants (rare)
Usage tips
Safety summary
Stearyl glycyrrhetinate has a strong safety profile with very low irritation and sensitization potential. It is non-comedogenic and suitable for all skin types, including sensitive and acne-prone skin. No significant safety concerns have been reported in cosmetic use.
Research notes
While glycyrrhetinic acid has been studied for anti-inflammatory and skin-lightening effects, fewer studies specifically examine stearyl glycyrrhetinate. Existing evidence supports its soothing properties, but more human clinical trials would strengthen the case for its efficacy.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in most regions including the EU, USA, and Japan. Generally recognized as safe at typical use levels.
- Common uses
