Orris root extract. Depending on how it is made, it darkened or lightened pigment in lab-grown skin.
What it does
Iris florentina (orris) root extract comes from the Florentine iris. In one lab study, some of its compounds raised pigment and others lowered it. An ethanol extract darkened lab-grown skin tissue, while chloroform and CO2 extracts lightened it. So the result depends on how the extract was made. No person was tested.
The evidence, graded
emergingIn one study, compounds from Florentine iris (orris) root pushed pigment in opposite directions. Germanaism B raised melanin; iriflorental and iripallidal lowered it. An ethanol extract, rich in the first, darkened lab-grown human skin tissue. Chloroform and CO2 extracts, richer in the others, lightened it. So the label name alone cannot tell you which way a product goes. The researchers work for Amway and have filed a patent.Yim 2025 · Molecules ↗
