CENTELLA ASIATICA LEAF CELL CULTURE EXTRACT.

Centella Asiatica Leaf Cell Culture Extract operates through a multifaceted biological mechanism, primarily attributed to its rich content of triterpenoid saponins, known as centelloids (including asiaticoside, madecassoside, asiatic acid, and madecassic acid). It significantly boosts fibroblast proliferation and increases the synthesis of crucial structural proteins like type I and III collagen, along with intracellular fibronectin, which collectively improve skin tensile strength and aid in minimizing scars and stretch marks. Furthermore, it stimulates the production of glycosaminoglycans, such as hyaluronic acid, leading to enhanced skin hydration and elasticity. The extract also possesses potent antioxidant properties, with phenolic compounds effectively neutralizing free radicals to protect cells from damage and decelerate skin aging. Its anti-inflammatory action is evidenced by its capacity to inhibit interleukin-6 (IL-6) production and suppress cytokine-induced inflammation. Specific saponins, notably asiaticoside, further reduce inflammation by inhibiting nitric oxide synthesis in vascular endothelial cells and attenuating the activity of inducible cyclooxygenase (COX-2) and lipoxygenase (LOX), key enzymes in inflammatory mediator formation, thereby alleviating redness and discomfort.
