We formulate our skincare to be skin-communicating to maximize the health and healing of the body’s largest organ on the outside, the skin.

Kat Burki , CEO and Founder

Our formulas are developed by a founding team that leverages three decades of research in health and nutrition


Kat identified three primary healing principles from Nutritional Biochemistry and applied these to a line of quality, efficacious products for the body’s largest organ - the skin. She works with the industry’s leading formulators to create products with complete ingredient synergy that reduce inflammation and optimize absorption for maximum health and healing of the skin.


After graduating Undergraduate studying Nutrition, Kat Burki received her Juris Doctorate in Healthcare Law.  To focus her career on Policy and Disease Management, she earned an additional Masters degree, studying Epidemiology.  Creating every product herself, she has revolutionized the view of skincare with her Nutritional Biochemistry approach to formulations.


Kat Burki Skincare is the culmination of over 10 years of research into nutritional biochemistry. Every formula is based on award winning research and is backed by clinical studies.


Where others focus on a hero ingredient, we look to the whole delivery system of healing, integrating the science of what we put in our bodies with the science of what we put on it.

Though each formula targets specific skin concerns, all Kat Burki solutions share three common goals: to maximize ingredient synergy (In other words: every ingredient supports the other), to suppress inflammation, and to optimize absorption to ensure the most effective delivery of the formula for your most radiant, rejuvenated, healthy skin yet.
