Key Ingredients: Conditioned culture fluid of immortalized human dental pulp stem cells, dipotassium glycyrrhizate, fullerene, etc. Effects and Efficacy: Formulated with "Cysay," which enhances regenerative power, at the highest concentration in REVI history, along with dipotassium glycyrrhizate, which has anti-inflammatory and anti-allergic effects, and "Syn-ake," which is said to be 10 times more effective than Argireline in wrinkle care. It enhances the regenerative and restorative power of stem cells, leading to firm skin. *Syn-ake is an ingredient that works on muscles to reduce wrinkles, artificially created from a peptide similar to the action of snake venom. It relaxes and stretches deep, hardened wrinkles caused by facial muscle contractions and aging, smoothing the skin.
