This was to reduce the amount of unnecessary additives found in the usual moisturisers bought in the shops.
Coconut cream is a good natural moisturiser, made by cold-pressing coconut flesh. This is all that makes up this moisturiser; to keep it from going off it goes in the freezer, which means it will last for up to a month.
The outer casing is made from the leftover part of the coconut flesh from the cold-pressing process. This is combined with silicone, which although not the most environmentally friendly material, is safe to use and can be frozen. Silicone is also durable, so this also means that the case can be used repeatedly, and filled up again with coconut cream which can be cheaply bought from any supermarket.
