Perilla Frutescens Leaf Extract is a leaf-specific extract of the shiso plant, containing higher concentrations of rosmarinic acid found predominantly in the leaf tissue. The leaf extract provides potent antioxidant and soothing benefits, making it ideal for formulations targeting redness, irritation, and environmentally stressed skin. Leaf-extracted perilla typically has a higher polyphenol content than whole-plant extracts.
