Our Amaira products use a airless pump technology that is designed to eliminate the long dip tube that is typical in a dispensing bottle.  This airless technology helps to maximize the amount of product that comes out of the bottle.  It also maximizes the shelf life of the product by eliminating exposure to outside air.   Before using the product, you first need to prime the bottle. Place your finger over the dispenser, and gently pump around 20 times to remove the air from the bottle. You might also have to shake it upside down a couple of times to let the contents flow into the nozzle. Please make sure you do not open the bottle as this can reduce the suction and oxidize the product, shortening its shelf life. Tip: Store your bottles upside down when they are running low to get every last drop out of the bottle and onto your skin.
