What it is: A sea-serum that works with the innovative Clarisonic® Opal Sonic Infusion System, designed to effectively deliver the choicest ingredients deep into the skin for dramatically soothing, firming, age-fighting results. What it is formulated to do: Clarisonic co-founder Robb Akridge, PhD, optimized the Anti-Aging Sea Serum specifically to complement the Opal's sonic infusion technology. Using his immunology expertise to promote skin health, he and his team of cosmetic scientists employed a multi-layered complex of marine extracts and botanicals to deliver exceptional results. This set contains: Opal® Anti-Aging Sea Serum. 2 x Replacement applicator tips. Opal's gentle sonic massage infuses Anti-Aging Sea Serum into the outer layers of the epidermis in 30 seconds. The effects are visibly smoother, firmer, more hydrated skin and minimized appearance of under-eye puffiness. Every soothing sonic pulse gently and immediately helps to immediately tighten, refresh, and energize the skin's appearance into a bright, youthful state. What else you need to know: Experience Clarisonic sonic skincare from start to finish: cleanse, then infuse for results that last for hours and benefits that build over time. The Opal Sonic Infusion System is dermatologist and ophthalmologist-tested, and gentle enough for daily use. Opal is rechargeable and convenient.
