specifically designed for use with the clarisonic opal Created for use in conjunction with Clarisonic’s peeper-perfecting Opal device, this serum was developed by immunology expert Dr. Robb Akridge to be optimized for the dynamics of sonic technology. His multi-layered approach uses marine extracts and botanicals that hydrate, firm, tighten and protect skin from future damage. Designed to help target crow’s feet and extra undereye ‘baggage’, it leaves skin feeling hydrated and refreshed. 1.7 oz
