What does it mean that Sienna Naturals is dermatologist-tested and approved?

Being dermatologist tested means that all Sienna Naturals formulas undergo clinical trials conducted by an independent laboratory and overseen, evaluated and approved by Board Certified Dermatologists and Registered Nurses. Each product is tested on more than 50 human subjects over the duration of several weeks before they are determined to be non-sensitizing and non-irritating to the skin.
