Rubus Fruticosus (Blackberry) Leaf Extract
What is Rubus Fruticosus (Blackberry) Leaf Extract?
Rubus Fruticosus (Blackberry) Leaf Extract comes from the leaves of the blackberry plant, a common bramble in the Rosaceae family. This botanical extract is obtained through water or solvent extraction of dried leaves, yielding a concentrate rich in tannins, flavonoids, and phenolic compounds. In cosmetics, it serves primarily as a skin conditioning agent with astringent and tonic properties, often incorporated into toners, serums, creams, and masks. It functions by forming a protective film on the skin's surface due to its tannin content, which temporarily tightens pores and provides a smoothing effect. Antioxidants in the extract help neutralize free radicals from environmental stressors. Additionally, it acts as a masking agent, contributing a mild, natural earthy scent to balance formula odors without synthetic fragrances.
