Story

An oil that’s good for your face, body, and hair – and for Yellowstone National Park. With a base of moisturizing oils, it’s got a woodsy, natural fragrance derived from actual Yellowstone florals like mountain hay-grass, sagebrush, and cedarwood. And every bottle supports conservation efforts in the park.

1 oz dropper bottle
Argan and jojoba oils
Mountain hay-grass, sagebrush, cedarwood

About Caswell Massey

Founded in 1752 (that's no typo) in Newport, Rhode Island, Caswell-Massey is truly America's original apothecary — making triple-milled soaps and traditional fragrances the good old-fashioned way. George Washington literally used the stuff, so you can bet it's plenty good enough for your post-workout shower.
