Hoya Lacunosa Flower Extract Bad Fragrance Synthetic and Natural No known benefits Hoya Lacunosa Flower Extract at a glance Derived from the flowers of the Hoya lacunosa plant Poses potential risk of skin sensitization due to fragrant compounds Lacking independent research to support supplier claims Alternative names include cinnamon-scented wax plant and porcelain flower extract Hoya Lacunosa Flower Extract description _Hoya lacunosa_ flower extract is derived from the flowers of the _Hoya lacunosa_ plant. Cosmetic suppliers of this ingredient claim that it can soothe and moisturize skin, but at the time of this writing, we could not find reliable third-party research to validate those benefits. Conversely, studies show Hoya lacunose flowers contain volatile fragrant compounds such as linalool. This raises potential concern of skin sensitization, contingent upon concentration. _Hoya lacunosa_ naturally emits a cinnamon-like aroma. One redeeming quality of _Hoya lacunosa_ flower extract lies in its antioxidant compounds. However, given the array of botanical extracts replete with antioxidants and devoid of volatile aromatic components, the use of this particular ingredient seems unwarranted. This plant also goes by alternative names such as wax plant, cinnamon hoya, cinnamon-scented wax plant and porcelain flower. As of August 2023, the Cosmetic Ingredient Review Expert Panel has yet to undertake a formal safety evaluation of Hoya lacunosa flower extract.
