At Aveda, The Art and Science of Pure Flower and Plant Essences, we believe that Nature is the best beauty artist of all. This is why we continually strive to increase our use of naturally derived ingredients whenever possible. Naturally Derived: Aveda uses the ISO standard 16218 when calculating the naturally derived percentage of its ingredients derived from plants, non-petroleum minerals, and other natural sources, including water. Naturally derived means that over 50% of the ingredient is natural (by molecular weight). Our commitment to deliver high performance, botanically-based products that are kinder to the planet – which is good for all of us and goes much deeper than our use of naturally derived ingredients.
