About Us

We exist to revolutionize what beauty means and change the complicated relationship between beauty and makeup.

We believe in free, easy, unrestrained beauty that celebrates simplicity and defies convention. Well-versed in the beauty routines that came before us, we are now liberating them, redefining beauty on our own terms and introducing makeup that feels as good as it looks.

Kosas is a visionary collection of nourishing, skin-flattering color cosmetics. Limited only by our own imagination and not bound by tradition, we create unparalleled blends that feel better, last longer, and make an impact.

We take our name from the philosophy of the five “kosas” of self. According to this philosophy, there are five intersecting and connected layers of self that communicate with each other: a physical layer, a vitalizing layer of energy, a sensory mental layer, a discerning intellectual layer, and a layer of truthful bliss. Beauty lives in each of these layers, not just in the physical.

At Kosas, our clean, skin-loving, botanical formulas and expert color pigmentation honor the beauty in every layer of the self. We undo conventional rules and create products that are beauty rebels, effortlessly applied, flattering across skin tones, and enriched with beneficial skincare ingredients.

With our eyes always fixed on transformation and the future of cosmetics, we are proud to be at the forefront of a beauty revolution, and we’re not about to stop.
