What it is
This ingredient is produced by growing callus tissue from sea holly (Eryngium maritimum) in culture and collecting the filtrate of that cell culture. Plant cell culture filtrates are used in cosmetics as a controlled, sustainable way to obtain botanical constituents without harvesting the wild plant. It is included in sunscreens as a conditioning component and does not act as a UV filter.
Safety & warnings
Cell-culture-derived botanical filtrates are generally well tolerated at the low levels used in cosmetics. As with any plant-sourced ingredient, sensitivity is possible in individuals prone to botanical reactions. It is water-based and not comedogenic.
Origin & sourcing
Derived from plant cell (callus) culture of the coastal plant Eryngium maritimum, then filtered to yield the active fraction.
Questions everyone asks
What is a callus culture filtrate?
It is the liquid collected from cultured plant cells grown in a lab, used to obtain botanical actives without harvesting the wild plant.
Does it provide sun protection on its own?
No. It is a skin-conditioning ingredient and is not a UV filter.
