Blue tansy, if you struggle with breakouts, is a must-know ingredient. It’s a poisonous flower if ingested, but we’re not suggesting consuming it. Blue tansy’s most important features are its antibacterial, antihistamine, and general anti-inflammatory ones. The color of the product is a vivid, deep blue, making it almost impossible to miss."The essential oil’s gorgeous, deep indigo color reveals itself only upon distillation, where it naturally produces a component called chamazulene," explains Michelle Gilbert, a holistic aromatherapist based in Cleveland, Ohio. "It’s this very transformation that gives us much of its therapeutic benefit."Blue tansy is a potent anti-inflammatory that helps reduce the appearance of redness and settle irritation, explains Patricia Wexler, MD, a New York City dermatologist. A natural multitasker, this calming essential oil can help mitigate various skin concerns, she says, including eczema and acne.The cycle of over-drying and excess oil production is a common problem among acne sufferers. In an attempt to combat the acne, drying agents are used and while they are initially successful at drying up the acne, the skin senses the dryness and begins to produce even more oil. This results in another, sometimes even greater, acne flare-up. Much better results are achieved when the skin’s natural oils are balanced, and the bacteria is dealt with. Herbivore Botanicals uses blue tansy to achieve just this effect.The Blue Tansy Resurfacing Clarity Mask by Herbivore is a natural clarifying and cooling gel mask that gently exfoliates, smooths, and resurfaces skin with a blend of Fruit Enzymes, Willow Bark and Blue Tansy Oil.Blue tansy is the active ingredient in their Lapis Facial Oil, as well. It contains Azulene, which acts as a powerful anti-inflammatory and antibacterial that aids in reducing redness and clarifying the complexion. Formulated for combination, oily, and blemish-prone skin types or any skin in need of relief from inflammation.
