We take customer feedback very seriously, and over the past five years we've received an incredible amount of requests from our customers asking for more probiotic formulas. And we believe that more probiotics would only enhance the benefits of the AO+ Restorative Mist and provide more restorative benefits to the skin microbome. So we created our Active Probiotic System, a line of restorative skin probiotic products infused potent probiotic blends and extracts into our products.
