The numbers, with the conditions attached.

Clinical Proof

Every figure on this page comes from Biodance's own clinical testing. We list what was measured, the condition it was measured under, and who it was measured on — because a percentage without those three things doesn't mean anything.

How to read this page

Rule Why
Change from baseline Every figure is the change itself, never a 100%-relative value — radiance 20.09%, not 120.09%. Both appear in our records as two notations of one value; mixing them reads as two different results.
Direction is named, not signed Figures carry no plus or minus. The metric states which way the measurement moved — hydration increase, pore area reduction — so a rise and a fall can never be read the same way.
Condition always stated After one use, after 15 applications, after eight hours of wear. A figure without its condition is not reported here.
Pore metrics are named Area, volume, size, density and count are different measurements. Without the metric name they look like contradictions.
In-vitro kept separate Lab results are labelled as lab results and never presented as human trial outcomes.
Combined use is disclosed Where a figure comes from using two products together, the pairing is stated.
