Limited Edition, The Conditioning Duo

Hydrate. Seal. Renew. The Conditioning Duo is a targeted performance system for hands, pairing our Activating Hand Serum with limited-edition Flash Masks to enhance absorption and visibly improve skin quality. Using occlusive technology, the masks help keep actives in their optimal window—reducing transepidermal water loss (TEWL) and driving deeper hydration than serum alone. The result is smoother, more hydrated, and visibly refreshed hands. Think of this as a streamlined version of the Power Pair. The Flash Masks deliver a flexible, occlusive seal with less coverage and shorter wear time—making it an effortless entry into treatment-based hand care, or a quick, high-impact reset.
