About Us

the-fam-0027.jpgSterling Minerals was founded by Katherine "Katie" Corkill when she became inspired to create products that would assist men and women in restoring the radiant healthy skin of their youth. It is her philosophy as an advocate of all things natural and organic when possible, to keep all skin looking young and healthy through protection from the suns’ harmful UV Rays, along with free radicals and environmental pollutants we are exposed to daily. Due diligence in pursuit of scientific research in knowing what goes into and onto our bodies, and how it affects us long term has been a lifestyle for her and her family for more than 25 years. Holistic and wholesome nutrition combined with natural and organic ingredients in skin care products are key to keeping us healthy and beautiful inside and out.

Katherine and her husband both suffered from sun damage, and as they entered into their 40’s their skin treatments began in order to try to correct and erase what years of sunbathing had done to them both. Many skin care products and makeup contain synthetic chemicals which created more discomfort and prolonged healing time. It was during this time Katherine began her quest to create products which would soothe and calm problematic skin without further irritation.

Following consultations with her Dermatologist, Professionals in the Cosmetic Industry, current Clients, and armed with her years of research on Holistic Care, she formulated her own unique mineral makeup line, Sterling Minerals. After two years of trial and error and product testing, a superior proprietary blend of the 1st and original mineral makeup to offer 3 formulas for specific skin types was created.  This was the result from utilizing the finest mineral powders combined with skin soothing botanicals…many of which are still used today in the Ancient Art of Ayurveda.

She then collaborated with Chemists, Aroma Therapists and Herbalists in order to provide a complimentary skin care line integrating modern science technology with nature's own botanicals which would assist with soothing and calming erythema and help prevent further inflammation and irritation for all skin types. Upon completion of another year of research and product testing, her new skin care line which she fondly refers to as ONATI was realized.

The ONATI name she cherishes is about more than just what it stands for, her husband and best friend of over 35 years created the namesake for her innovative skin care line. Through this love and support from her family to help with her tireless efforts to create the entire ensemble of skin healthy products, is what she attributes to the success and fulfillment of her achieving her dream.

Sterling Minerals and ONATI Skin Care were created out of a growing need by many men and women also wishing to stop using irritating, ageing, and harsh ingredients on their skin and to assist them with putting their best “Face” forward in whatever their life’s pursuits. Katherine also wanted to provide products that would reduce down time after a cosmetic procedure or skin treatment from sun damage and to prevent further exacerbation of acne or rosacea.

Her commitment is to continue her never ending research and provide truth, integrity, ethics and education to anyone who seeks it. She will always continue to strive to offer result driven formulas to those who will accept nothing less.

Katherine is also an author of all things relating to the beauty industry, and has written countless articles based on scientific research and data.  She extends this research to her customers and has become the "go to" resource for women wanting to know more about the products they use everyday.  Alongside her colleagues in the science community, she is also a recognized and respected author and beauty industry expert at Personal Care Truth.  She always presents the "sometimes" inconvenient truth in cosmetic research, yet will dispel any pseudo science created simply to malign or inflate benefits of some ingredients by those with a target specific marketing agenda.

To all women……Always exude confidence……Live life to the fullest……Achieve your goals……and let "Sterling Minerals and ONATI" help restore and keep that rose petal softness and lovely glow of youthful, healthy skin we all enjoy.
