The live probiotic bacteria is encapsulated in very small crystals to keep the cells alive, as well as the prebiotic inulin, also is un-soluble in oils and fats and will feel like small crystals. The crystals are the “good stuff”. Humidity, in the air or on the skin, will often dissolve the crystal very fast, but sometimes humidity is low, and the crystals feels like fine peeling. Add a drop of water to the skin or fingers/hands and the crystals will instantly dissolve.
