What Is Perilla Ocymoides Seed Extract?

Perilla Ocymoides Seed Extract is derived from the seeds of the shiso plant. Unlike the leaf extract which is rich in rosmarinic acid, the seed extract contains high levels of omega-3 alpha-linolenic acid (ALA) and lignans with antioxidant properties. It provides nourishing and protective benefits to the skin while delivering a different phytochemical profile than leaf-derived extracts.

Key Skin Benefits

+ Omega-3 fatty acids — ALA supports skin barrier and reduces inflammation
+ Lignan antioxidants — unique seed compounds provide oxidative protection
+ Skin nourishment — fatty acids improve skin suppleness
+ Complementary to leaf extract — different phytochemical profile

Pros

+ Rich in essential fatty acids not found in leaf extracts
+ Dual antioxidant + nourishing activity
+ Natural and renewable plant source
+ Complements perilla leaf extract for full-plant benefits

Cons

− Less researched than perilla leaf extract
− Oil content requires emulsification in water-based formulas
− Oxidation-sensitive — requires antioxidant protection
− Limited supplier availability
