That poetically romantic serum dropper may seem like the perfect way to dispense your facial oil or serum, but did you know you may be causing deterioration of the vital nutrients every time you open the product? Because air is an oxidant, it can age whatever it comes in contact with. Many of the ingredients in our facial oils lose their potency and begin to deteriorate over constant exposure to the air. That is the case with every facial oil on the market. Many companies will add vitamin E as a way to prolong the effectiveness of the oils. Unfortunately there are a great deal of potential contaminants in Vitamin E, including GMO's (Genetically Modified Ingredients). To ensure your facial oil retains maximum antioxidant activity for your skin, all of our serums are packaged with pump applicators.
