Licorice Root Extract

An extract from Glycyrrhiza glabra containing multiple bioactive compounds, of which glabridin is the most studied for skin brightening. Glabridin inhibits tyrosinase and UVB-induced pigmentation, while glycyrrhizin has anti-inflammatory properties. Human clinical data shows reduction in hyperpigmentation and melasma, with a tolerability profile substantially better than hydroquinone — no risk of ochronosis or rebound hyperpigmentation on discontinuation. Licochalcone A (from a different licorice species) is widely used for its soothing and anti-inflammatory effects in sensitive skin products. Effective at reducing PIH and uneven tone with long-term use. Typically formulated at 0.5–2% standardised for glabridin content.
