The special formula with timed and extended-release requires oil. Also, oil does better for the delivery of the oil-soluble vitamins and for lubrication of the vagina in order to prevent pain during sexual intercourse. It is also good for moisturizing the vaginal mucous membrane. A thin film of oil on the mucosa protects it from pathogens like fungi or bacteria. Our product uses only food-grade all-natural vegetable oil (e.g., palm and palm kernel oil) as its base. No synthetic or petroleum-based oil is used.
All live forms including bacteria and molds need water to grow. Mars does not have life. A major reason is that Mars does not have water.
If these products are oil-based, bacteria and mold cannot grow even with loaded nutrients because the products are water-free. Therefore, we can avoid using preservatives. This is better than water-based products. Because water naturally supports mold and bacteria, water-based products must add toxic preservatives, like parabens, to prevent mold or bacterial growth. Parabens have some serious side effects (https://www.100percentpure.com/blogs/feed/5-common-side-effects-of-parabens). Therefore, preservatives-free means safer products.
