Ylang Ylang is a widely appreciated essential oil derived from the yellow, scented blossoms of the Cananga tree, which is native to tropical Asia. It is composed of many chemicals, with its own pros and cons. In addition to its pleasant scent, which is used in cosmetics, Ylang Ylang is thought to have antimicrobial and antioxidant properties, as well as being an insect repellent. It is also believed to have a calming effect, which has been supported by some recent studies. Though this could be beneficial when inhaled as part of aromatherapy, it is unlikely to have any impact on skincare.
