Licorice Nano Extract is a nanotechnology-processed derivative of licorice root (Glycyrrhiza glabra) rich in glabridin and liquiritin, used to inhibit tyrosinase activity and reduce hyperpigmentation while soothing inflammation. The nano-sized particles are intended to improve penetration and bioavailability compared to conventional extracts.
| Reported effect | How often | Notes |
|---|---|---|
Mild transient irritation or stinging | Uncommon | Usually self-limiting, more likely on sensitive or compromised skin. |
Contact dermatitis / allergic sensitization | Rare | Documented with botanical extracts; patch testing advised for sensitive individuals. |
Erythema or redness | Rare | Generally transient at typical use concentrations. |
Concerns regarding nanoparticle penetration/systemic exposure | Very rare | Theoretical safety question raised in research; data on long-term nano-delivery effects remain limited. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
