Airless Bottles are generally made of PP plastic, and ordinarily used for shave products and facial moisturizers. The bottom of these bottles has a piston that pushes product up and out. With the piston following the product, it means no air is getting into the bottle hence the name “airless bottles”.
This is important because air contains oxygen, and oxygen may cause damage and degradation in cosmetics. Use airless pumps for after-shave gel, face cream, pre-shave oil, and shaving cream.
