What Is Perilla Frutescens Extract?
Perilla frutescens, often called shiso or perilla, is a leafy herb in the mint family that grows across East Asia. Perilla Frutescens Extract is made by taking the whole plant, drying or macerating it, then soaking it in a solvent such as water, glycerin or a mild alcohol. The liquid pulls out helpful compounds like omega 3 rich fatty acids, rosmarinic acid and flavonoids, after which the mixture is filtered and concentrated into a stable, skin friendly solution.
The herb has a long record in cooking and folk skin care, especially in Japan, Korea and China where crushed leaves were applied to calm rough or itchy skin. Modern formulators picked up on these soothing traits in the early 2000s and began adding the extract to commercial beauty lines. You can now spot Perilla Frutescens Extract in lightweight serums, calming sheet masks, daily moisturizers, anti aging creams, after sun gels and even scalp or beard products where extra softness is wanted.

Comedogenic Rating
Rating: 1 out of 5. Perilla Frutescens Extract has a very low likelihood of clogging pores because it is used at relatively low percentages in formulas and contains lightweight omega 3 rich fatty acids that absorb easily rather than sitting on the surface. Its molecular profile is closer to a thin botanical infusion than a heavy plant oil, so it generally leaves pores clear. This makes it a safe pick for people prone to acne or breakouts. Most products featuring the extract also pair it with non occlusive carriers that further reduce the risk of congestion.
Summary
Perilla Frutescens Extract is valued in cosmetics as a gentle skin conditioning agent that softens hydrates and supports the skin barrier. Its mix of omega 3 fatty acids, rosmarinic acid and flavonoids helps lock in moisture while offering a touch of antioxidant protection that can calm visible redness and daily stress. Although not as famous as ingredients like aloe or green tea it has carved out a steady spot in K beauty inspired serums moisturizers and calming masks thanks to its light feel and soothing payoff. Overall it is considered very safe with few reported reactions but as with any new skincare ingredient it is wise to do a quick patch test to make sure your skin agrees.
