What Is Perilla Frutescens Seedcake?
Perilla Frutescens Seedcake is the solid material that remains after oil is pressed from the seeds of the Perilla frutescens plant, a member of the mint family valued in East Asian cooking and herbal traditions. While the oil has long been prized for its nutty flavor and healthy fats, the leftover seedcake was once seen as little more than farm feed. Researchers later found that this residue still holds helpful skin-friendly compounds such as plant proteins, fiber and a small amount of omega-rich fatty acids, which sparked interest in beauty labs.
To create the ingredient, ripe perilla seeds are cleaned, mechanically cold-pressed to extract most of the oil, then the remaining cake is ground and sifted into a fine powder. Because heat is kept low, the nutrients stay intact. The resulting powder blends easily with water or oils, making it handy for cosmetic formulators.
Today you can spot Perilla Frutescens Seedcake in soothing face masks, daily moisturizers, lightweight lotions, anti-aging creams and after-sun gels where a boost of gentle skin conditioning is welcome.

Comedogenic Rating
Rating: 1 / 5
Perilla Frutescens Seedcake contains only traces of the oil that was pressed out of the seeds and what little fat remains is rich in lightweight omega-3 acids that absorb easily. The bulk of the powder is protein and fiber, both of which sit on the surface without blocking pores. Because of this low oil content and its quick-absorbing nature the ingredient has a minimal tendency to clog follicles, earning it a rating of 1.
That means it is generally suitable for skin that is prone to acne or breakouts.
Real-world pore-clogging risk still depends on the full formula and how heavily a product is layered, so very oily skin types may want lighter textures when possible.
