Avene dermatological laboratories have invented patented packaging technology, which prevents air, microbes and other contaminants from entering the tube. This keeps the contents of the tube sterile, which means we do not need to add preservatives to the delicate, exceptionally gentle formulations we produce for people with very sensitive skin.
Not only do our Sterile Cosmetics remain uncontaminated in your home, their production takes place in carefully constructed sterile environments, using the same standards kept by the pharmaceutical prodution of medicines, including the systematic control of raw materials. This means that even in the production process we do not need to alter or treat our raw materials in any way that may reduce their efficacy or alter their affect on your skin.
The D.E.F.I (Device for exclusive formula integrity) cap is a revolutionary approach to packaging design. We have completely eliminated the need for preservatives through combining the D.E.F.I Cap with sterile production methods. The products remain completely sealed off throughout their lifespan.
