Science
Mechanism of Action
This ingredient is understood to exert anti-inflammatory effects primarily by inhibiting mast cell degranulation and reducing the expression of inflammatory cytokines in keratinocytes. These actions collectively help to decrease skin hyperplasia, parakeratosis, dermal edema, and mast cell infiltration. The broader Alpinia genus is also recognized for its antioxidant properties, which aid in neutralizing free radicals, contributing to overall skin conditioning.
