Enhanced Solubility & Gentler Epidermal Delivery
Compared with native glycyrrhetinic acid, the glucuronide conjugation greatly elevates water solubility, eliminating common formulation hurdles with lipophilic licorice actives. This structural tweak supports better epidermal penetration while lowering local irritation risk, a key advantage for sensitive-skin formulas. It integrates smoothly into aqueous toners, essences and lightweight serums without heavy solubilisers that may trigger discomfort for reactive skin.
Multi-Target Anti-Inflammatory & Redness Relief
It moderates NF‑κB signalling and suppresses pro-inflammatory cytokine release including TNF‑α and IL‑1β, while interfering with arachidonic acid inflammatory cascades. The ingredient helps calm UV-induced erythema, post-exfoliation irritation and transient redness without steroid‑like side effects. This makes it well suited for soothing serums, post-procedure care and barrier-repair products targeting easily inflamed complexions.
Tyrosinase Modulation for Even, Gentle Brightening
Beyond soothing action, glycyrrhetinic acid glucuronide regulates tyrosinase activity to restrain excessive melanin synthesis, helping fade discolouration and patchy tone. Unlike many potent brightening agents, it works in a mild, non-irritating way, pairing well with barrier-supporting ingredients. It offers formulators a licorice-origin brightening option for sensitive skin that cannot tolerate harsher depigmenting actives.
Antioxidant Protection & Skin Barrier Stabilisation
This licorice derivative scavenges reactive oxygen species triggered by blue light and environmental pollutants, mitigating lipid peroxidation and matrix degradation. It also helps stabilise hyaluronic acid within the dermis and supports tight junction integrity, cutting transepidermal water loss. Combined anti-oxidative and anti-inflammatory effects support long-term skin resilience and reduce visible signs of inflammatory photoageing.
