If two formulas must be kept separate and be mixed only immediately before use, our Fusion Pack offers formula separation and controlled mixing. One formula is in a thermoform/blister chamber, the other in a packette. When pressure is applied to the chamber, the formula evacuates and mixes into the packette. The formula is only activated when needed, and potency of the actives is maintained resulting in a fresh mixture every time. An applicator pad can also be included for a more luxe application.
