Normally, my skin is not its best self come January. The cold, dryness, and lack of daylight bring out a combination of rednessanddullness—something I always forget is possible until I see it. But this year, miraculously, I’ve avoided my dreaded January Skin™, and I think I have one thing to thank: blue tansy. Three of the products in my regular rotation feature the jewel-toned ingredient: the Kate McLeod Face Stone Moisturizer, Testament Beauty Sleeping Mask, and Lord Jones Sublime Pore Detox CBD Face Oil.
Aside from the fact that I knew blue tansy A) was pretty, B) smelled nice, and C) seemed to calm my sensitive skin, I didn’t know much about the ingredient. So I reached out to Tracy Evans MD, MPH, board-certified dermatologist and the medical director of Pacific Skin and Cosmetic Dermatology, to shed some light.
“Blue tansy (Tanacetum annuum) has blooms that are actually yellow in color and is cultivated in Morocco,” explains Evans. So then, you may ask, how does it get that recognizable scent and color? “The oil has a sweet, herbal fragrance due to its camphor content,” explains the derm. “When the flowers and the stems are gathered and steam-distilled, one of the components of the oil, chamazulene, is released. When this chemical is heated, it turns a deep-blue, indigo color.”
Aside from me and my red, inflamed skin, those with acne-prone skin may find blue tansy beneficial. “Although there is little evidence-based research, two components of the oil may have some positive anti-inflammatory actions that could be helpful for acne,” says Evans. “Sabinene and camphor both can aid in inflammatory disorders. As acne has an inflammatory component, especially when it is red and irritated, this oil may be helpful to calm the redness in the skin.”
While the ingredient is generally well tolerated, it is an essential oil, which some people find irritating. “People who are sensitive to herbal supplements should be cautious before using this topical,” says Evans, who also recommends a patch test. “Before using this oil, check for potential allergies by applying a small amount on the inner arm for three days to make sure no contact allergies appear on the skin.”
