Mechanism of Action
Raspberryketone Glucoside (RKG) employs a multi-faceted approach to improve skin tone and youthfulness. It precisely inhibits melanin synthesis by activating the IL6/JAK1/STAT3 signaling pathway, which consequently downregulates the transcriptional activity of MITFa and the expression of its downstream genes, TYR and TYRP1a. Furthermore, RKG acts as a potent antioxidant and free-radical scavenger, neutralizing active oxygen and lipid peroxides, and scavenging nitric oxide within skin cells to reduce tyrosinase activity. This comprehensive action helps protect skin elasticity and prevent UV-induced damage, enhancing the skin's overall state.

Key findings
- 01 Raspberryketone Glucoside noticeably inhibited melanogenesis in B16F10 cells (in vitro) and on zebrafish (in vivo). This effect was attributed to the activation of the IL6/JAK1/STAT3 pathway, leading to reduced MITFa transcriptional activity and suppressed expression of TYR and TYRP1a genes.

Safety
Safety Profile
Raspberryketone Glucoside has not undergone a direct safety assessment by the Cosmetic Ingredient Review (CIR) or SCCS. While Raspberry Ketone (RK), a related compound, was granted 'Generally Recognized As Safe' (GRAS) status by FEMA in 1965 for food use, this designation does not directly apply to RKG's use in cosmetics.
