Proven Results + Responsible Testing: Every Bioelements formula is clinically proven to provide results. We conduct dermatologist testing, and many formulas have strict consumer perception testing by 3rd party experts to quantify benefits. We cite independent clinical evaluations of ingredients, and in-vitro + in-vivo testing to validate claims where applicable. And, we follow strict formula quality control via stability + clinical testing to ensure safety, effectiveness and performance. We never test on animals.
