What Is Asperula Odorata Flower/Leaf Extract?
Asperula Odorata Flower/Leaf Extract comes from the flowers and leaves of sweet woodruff, a small woodland herb in the Rubiaceae family. This plant has a pleasant hay-like scent due to coumarin, one of its naturally occurring compounds, along with flavonoids and tannins that offer mild soothing properties. Folk tradition valued sweet woodruff for fragrant sachets and spring beverages, and its gentle skin feel led formulators to explore it for beauty care.
The extract is usually produced by harvesting the aerial parts when the plant is in bloom, drying them to concentrate aroma compounds then soaking them in a cosmetic-grade solvent such as water, glycerin or a mix of water and alcohol. The liquid is filtered and standardized so each batch delivers consistent activity, after which it is blended into creams or serums.
You will most often see Asperula Odorata Flower/Leaf Extract in moisturizers, anti-aging creams, soothing masks, toners and lightweight leave-on lotions where a plant based skin-conditioning touch is desired.

Rating: 0-1 (very low)
Asperula Odorata Flower/Leaf Extract is mostly made of water soluble compounds such as flavonoids, tannins and trace coumarin, with virtually no heavy oils or waxes that could block pores. Formulas typically use it at low concentrations for its soothing touch, so the risk of buildup inside follicles is minimal.
