Urtica Dioica (stinging nettle) extract is a plant-derived ingredient valued for its anti-inflammatory, antioxidant, and astringent properties, often used in formulations targeting oily skin, irritation, or scalp conditions. It contains flavonoids, polyphenols, and minerals that may help calm and tone the skin.
