Thomasina (Tammy) Demos draws wisdom from more than two decades in the skin care industry, her years as a nutrition and fitness coach, and her pre-med degree from Creighton University. With OUSIA, Tammy introduces topical skin nutrition: potent, ethical, and intuitive formulas that optimize skin healing. In a market saturated with products, none spoke louder to Tammy than nature’s own medicine. During her own holistic healing journey, Tammy uncovered bright sources of rejuvenation that she now infuses into OUSIA. Through morning and evening walks with her dogs in the Colorado mountains or while enjoying nature in her hometown of Evergreen, Colorado, Tammy taps into the curative potential from the earth around her—OUSIA is the fruit of that connection.
