Our take
Is Pentylene Glycol Glycyrrhiza Glabra (Licorice) Root Extract a Good Ingredient?
Rated Good because licorice constituents show supportive evidence for tone-evening and calming, though outcomes depend on how well the active fractions are standardized and concentrated. That variability across extracts is what keeps it from a higher rating.
What it does
Skin Benefits
Helps diminish the look of dark spots while promoting a brighter, more uniform complexion; also comforts visible redness. Results can vary with concentration and extract quality.
Where you'll find it
Uses in Skincare & Cosmetics
Used in brightening serums, targeted dark-spot treatments, calming moisturizers, and eye creams to support tone evenness.
Before you use it
Generally safe for topical use, though botanicals can cause irritation or allergic reactions in sensitive individuals; patch testing is prudent. No widely recognized topical regulatory limits for licorice extract at cosmetic use levels.
