Description

Liquorice Root Extract — Brightening, Soothing Botanical Active for Hyperpigmentation & Skin Tone Correction Systems.

Liquorice Root Extract (Glycyrrhiza glabra) is a high-performance botanical active widely used in cosmetic formulation for its ability to visibly brighten the skin, reduce hyperpigmentation, and improve overall skin clarity.

Rich in glabridin, a naturally occurring compound known to help inhibit melanin production, this extract works to fade dark spots, even out skin tone, and support a more radiant complexion. At the same time, glycyrrhizin provides soothing and anti-inflammatory benefits, helping to calm redness and irritation, making it especially valuable in formulations targeting post-acne marks, sensitive skin, and uneven tone.

Its antioxidant profile further supports skin health by helping to neutralize free radicals and reinforce the skin barrier, making it a versatile addition to both brightening and restorative systems.

At Skin Foodie, Liquorice Root Extract is positioned as a targeted brightening and skin-tone-correcting active for formulators creating high-performance solutions for hyperpigmentation, post-inflammatory marks, and sensitive skin.
