This is a relatively simple formulation. GABA smoothes wrinkles by the mechanisms similar to Botox: relaxing the muscle.
There are ingredients in here that improve the blood circulation in the skin.
Should not be used repeatedly and excessively because it contains eugenol (clove oil), a potent skin irritant and will cause inflammation when overdosed.
But honestly for a price this high I would expect more. For this I took away one star.
Safety alert: Cautious
