About this Brand

Kosas quite simply takes our breath away. It’s a gold standard for luxe, hydrating, better-for-you ingredients combined with a sense of color and beauty that only an artist could dream up.

Sheena Yaitanes, a painter who studied biology, chemistry, and art history, founded this exquisite brand (pronounced ko-shas) in 2015. She uses a color-mixing technique favored by master artists to create what she describes as “elevated color cosmetics.” Her painting background guides what pigments to use and how to match skin tones to the right products.

  • Luscious products, especially lipsticks and blushes
  • Shades picked artfully to match either warm or cool skin tones
  • Designed for women on-the-go – can be applied in the back of a Lyft
  • Free of parabens, phthalates, BHA/BHT, mineral oil, propylene glycol, polyethylene glycol, phenoxyethanol, fragrance, petrolatum, vitamin A, retinoids, and retinoid derivatives
  • Name “Kosas” reflects the five interconnected layers, or “kosas,” of the self: the physical, energetic, mental, intellectual, and soul
  • Based in Los Angeles, California

From Kosas:

“We source ingredients for two reasons: extreme nourishment and supreme luxury. We choose only the ones that deliver both.”
