Huxley Secret of Sahara Oil Essence is a unique, oil-like essence that provides hydration and nourishment without feeling oily or greasy. It is formulated with all natural ingredients like prickly pear seed extract, Yerba mate leaf, & acai berries. It has a lightweight serum texture that absorbs quickly and it doesn't make my oily skin feel greasy at all. This essence leaves my skin feeling very smooth, hydrated & rejuvenated. It does have a strong perfumey fragrance that I am not a fan of.
