Technique & Craft
Melanin synthesis occurs within epidermal melanocytes via an oxidation cascade catalyzed by tyrosinase. When skin experiences UV radiation or inflammatory trauma (such as an acne blemish), tyrosinase oxidizes L-tyrosine into L-DOPA and dopaquinone.
Glabridin—the primary active isoflavonoid extracted from Glycyrrhiza glabra—functions as a reversible competitive inhibitor of both tyrosinase and dopachrome tautomerase. It binds directly to the enzyme's catalytic site without cytotoxicity, preventing the synthesis of both eumelanin (black/brown pigment) and pheomelanin (red pigment) without altering normal baseline skin coloration.
In addition to glabridin, licorice root contains licochalcone A, a chalconoid with potent anti-inflammatory properties.
It directly inhibits the release of pro-inflammatory prostaglandin E2 (PGE2) and suppresses inducible nitric oxide synthase (iNOS). By halting inflammation immediately after an acne breakout, licorice prevents post-inflammatory erythema (red marks) from transitioning into stubborn post-inflammatory hyperpigmentation (brown marks).

Yes! Licorice root is considered one of the gentlest, safest botanical brightening agents in dermatology. Unlike harsh hydroquinone, licorice does not irritate sensitive skin, cause rebound hyperpigmentation, or bleach normal skin cells.
Yes! Combining licorice root with niacinamide and vitamin C creates a powerful multi-pathway brightening routine. Licorice and vitamin C inhibit tyrosinase enzymes, while niacinamide blocks the transfer of pigment into skin cells.
Because skin cell turnover takes 28 to 40 days, visible fading of red and brown post-acne marks typically begins around 4 to 6 weeks, with significant improvement at 8 to 12 weeks of daily use paired with SPF 50.
