Steam distilled from flowers of trees grown in Ecuador and Madagascar, Ylang Ylang essential oil has a sweet, romantic aroma and moisturizing properties, making it a key ingredient in many luxury skin and hair products. Ylang Ylang is often classified as a heart note because it emerges just as the top notes begin to dissipate. Add it to your daily moisturizer, a steamy bath, or homemade hair mask for a relaxing, luxuriously aromatic at-home spa day.
