FREEZE-DRYING
REMOVE THE WATER,
NOT WITH HEAT
FREEZE-DRYING FREEZES THE SOLUTION, THEN LOWERS THE PRESSURE UNTIL THE ICE TURNS STRAIGHT INTO VAPOUR. THE WATER LEAVES WITHOUT EVER BOILING, SO THE ACTIVE IS NEVER COOKED. IT IS THE SAME TECHNIQUE USED FOR ASTRONAUT FOOD — AND THE REASON A FREEZE-DRIED STRAWBERRY KEEPS ITS SHAPE, ITS COLOUR AND ITS TASTE.
WHAT IT CHANGES
FOR GRUME
THE MOMENT AN ACTIVE MEETS WATER, IT STARTS TO BREAK DOWN. CONVENTIONAL SKINCARE IS UP TO 95 % WATER, SO IT NEEDS PRESERVATIVES TO STAY SAFE ALL THE WAY FROM THE LAB TO YOUR BATHROOM. WITHOUT WATER, OUR ACTIVES KEEP FOR YEARS WITHOUT LOSING THEIR PROPERTIES. NO PRESERVATIVE. NO TEXTURISER. NO FRAGRANCE TO MASK ANYTHING. ONE BEAD, ONE ACTIVE, NOTHING ELSE.
