What it is
Rubus arcticus callus extract is produced by culturing callus (undifferentiated plant cells) from the arctic bramble, allowing standardized production of plant phytochemicals without harvesting wild plants. In skin care and sun care it is used as a conditioning and antioxidant-associated botanical, typically at low percentages. The cell culture approach is favored for consistency and sustainability.
Safety & warnings
As a water-based botanical extract used at low levels, it is not considered comedogenic and is generally well tolerated. As with any botanical, individuals with known plant sensitivities may wish to patch test. No distinctive allergen concerns are commonly associated with this ingredient.
Origin & sourcing
Plant-derived. It is obtained through plant cell (callus) culture of Rubus arcticus tissue under controlled laboratory conditions, followed by extraction.
