Dr. Ruthie Harper
Ruthie Harper, MDAs seen on:


Ruthie Harper, MD, is a leading physician in the areas of non-surgical aesthetics, DNA-based skin care solutions, nutritional medicine, and optimal health and wellness. Dr. Harper developed the SKINSHIFT® line of skin care products and nutritional supplements to improve the health and appearance of your skin as well as your overall health.

Dr. Harper began her career as a Board Certified Internist and was later promoted to Emergency Room Director at Doctor’s Hospital of Jefferson in Louisiana where she quickly realized that traditional medicine provides ways to treat the symptoms of disease, but is not designed to prevent disease or regain optimal health. She retraced her medical training back to basic biochemistry, realizing that if a person had perfect cellular function, they would be optimally healthy and disease free.

This knowledge led Dr. Harper to research and develop scientifically based health and beauty products that move beyond temporary fixes that use drugs or other technologies and transform both the health and the appearance of patients worldwide.

Using science as a foundation, Dr. Harper designs innovative treatment programs for patients seeking to optimize their overall health, beauty, and wellness. Her breakthrough treatments for macular degeneration and thyroid conditions make her a leading expert, frequently speaking at medical conferences across the nation. Her pioneering work also targets disease prevention, including heart disease, diabetes, obesity, cancer, autoimmune conditions, and neurodegenerative diseases.
