Argan oil has been a big hit on the cosmetics scene over the last few years. This wonderful anti-ageing oil is high in Omega-6 fatty acids as well as Vitamin E which is a powerful antioxidant. The process of cold-pressing argan oil takes a long time. It is estimated that it will take 20 hours work to produce one litre of oil, so you can see why it is so expensive. The oil itself has regenerative and firming qualities owing to its fatty acids and antioxidants, which helps maintain the elasticity of the skin.
