Don’t be surprised if you think you might look a little younger after chowing down on your favorite Szechuan dish. According to Indena, an ingredient research and supply company, an extract from the husks of the Szechuan pepper may very well possess anti-aging effects. The extract zanthalene was originally investigated for its anti-itch properties, although once scientists discovered that application caused a tingling sensation, potentially inhibiting synaptic transmission, they decided to take a closer look at the ingredient to determine its anti-aging capabilities.
The study involved a group of 21 females, ages 35 to 65, divided into three study groups. The first group applied formulations containing 1 percent zanthalene and the second group applied a formula containing 2 percent of the experimental ingredient. The third group used a formula containing a completely different ingredient that causes a similar tingling sensation. According to participant evaluations, the group applying the 1 percent formula reported experiencing a lifting effect and improved skin roughness. Results were less favorable with the group using the 2 percent formula.
The contradicting results may be based on varying concentration levels as well as factors associated with participants’ different skin types. The company plans to continue its research to explore the muscle relaxing capabilities of the ingredient.
