With its natural antiseptic and astringent properties, fennel oil is perfect for both oily and mature skin. As an effective toner and cleanser, it helps balance oily skin while reducing the appearance of fine lines and wrinkles. By boosting circulation to the skin’s surface, fennel oil also helps minimize the effects of water retention. Native to the Mediterranean, fennel has been cherished since ancient times and was cultivated by the Romans for its flavorful fruits and tender shoots.
