Abstract

Two main types of argan oil co-exist: edible and cosmetic. Each type comes from the kernels of argan fruit but following slightly different preparative processes. The nutritional and dermoprotective properties of edible and beauty argan oil, respectively, have remained traditional knowledge for centuries. During the last twenty years, argan oil fame has spread over the world. This success has also attracted the attention of scientists and triggered scientific investigations in both chemical and biology fields. Some traditional claims have been confirmed. This peer-reviewed article is aimed at explaining argan oil preparative process, its limits together with the reasons of argan oil success in the food and skin care domains.
