What it is
Crithmum Maritimum Callus Culture Filtrate is produced by growing undifferentiated plant cells (callus) of sea fennel, a salt-tolerant coastal plant, in a controlled culture and then collecting the filtered liquid fraction. This plant-cell-culture approach yields a consistent, sustainable supply of the plant's metabolites without harvesting wild populations. It is used as a skin-conditioning ingredient, typically at low levels within the active or supporting portion of a formula.
Safety & warnings
Plant cell culture filtrates are generally well tolerated; as with any botanical-derived material, sensitive individuals may occasionally react to residual plant constituents.
Origin & sourcing
Biotechnological; derived from in vitro callus (plant cell) culture of Crithmum maritimum, with the culture medium filtered to obtain the active filtrate.
Questions everyone asks
What does callus culture mean?
Callus is a mass of unspecialized plant cells grown in a lab culture; the filtrate is the liquid collected after filtering that culture, offering a consistent, sustainable source of the plant's metabolites.
Does it provide UV protection?
No. It is a skin-conditioning botanical ingredient and does not act as a UV filter.
