NWT, Box is a bit dirty from storage. One Mask Retails for: $16 Four pack retails for: $60 The Aceology Probiotic Restoring Biodegradable Mask is a super light sheet mask that soaks your skin in beneficial ferments to replenish and renew your complexion. Our cryogenically-fermented blend of 10 Probiotics, provides a moisturizing, strengthening and smoothing action while a highly absorbable form of Hyaluronic Acid instantly hydrates. The 10 strains of Probiotics are extracted through a two-stage cold-aging technique. The first stage maximizes the active substances in each probiotic; the second stage captures and increases the stability of these actives at cryogenic temperatures (-70°C). The good bacteria found in this complex rehydrates, smooths, improves skin texture, and supports your moisture barrier. Mega-hydrator, Hyaluronic Acid, complements this by drawing moisture into the skin, boosting water retention, and encouraging a plump, smooth complexion. The restorative ingredients in this formula are delivered via a planet-friendly Lyocell biodegradable mask which feels incredibly silky and light on your skin. When pressed onto your face, the smooth fibers adhere comfortably without slipping off, making this hydrating mask one your skin will love drinking up.
