Perilla frutescens is an annual herb of the mint family (Lamiaceae), native to East Asia (China, Korea, Japan, Vietnam). Commonly known in English by names such as shiso, beefsteak plant, or Japanese basil, perilla features serrated leaves in green or purple varieties and aromatic stems.
This botanical extract is a "barrier-builder," designed to soothe chronic sensitivity, restore lost moisture, and protect the skin from the visible signs of aging.
What It Does
-
Antioxidant Protection: Perilla extracts contain high-levels of phenolic compounds like rosmarinic acid, flavonoids (e.g., apigenin, luteolin) and unsaturated fatty acids. These afford free-radical scavenging and oxidative-stress mitigation.
-
Anti-Inflammatory & Soothing: Studies report that perilla leaf extract suppressed inflammatory enzymes (e.g., NO, COX-2), reduced mast-cell infiltration and down-regulated pro-inflammatory cytokines in skin models.
-
Barrier & Skin-Shield Support: The seed form (and oil thereof) is rich in omega-3 alpha-linolenic acid and linoleic acid; this supports barrier-lipid synthesis, improves hydration retention and refines texture. Tone / Clarifying / Calm-Complexion Support: Emerging evidence suggests that perilla may help calm redness, reduce sensitised skin responses, and support an even-tone appearance. UV / Environmental Stress
-
Resilience: One study found that perilla leaf extract improved keratinocyte response to UVB exposure, implying benefit for photo-aged or stressed skin.
Suitability & Target Skin Types
Perilla extract is highly versatile. It is especially beneficial for:
-
Sensitive, red or reactive skin needing calming support
-
Oily or combination skin where barrier and texture support is needed
-
Environmental-stress exposed skin (pollution, UV) seeking antioxidant and resilience support
-
Mature or dehydrated skin where antioxidant and barrier-repair support are advantageous
Because of its gentle yet active nature, perilla extract fits well in everyday skincare as well as calming treatments. As always, patch-testing is recommended for highly sensitive skin.
Key Benefits of Perilla Seed Extract in Skincare
- Unmatched Omega-3 Content: With up to 60% Alpha-Linolenic Acid, it provides deeper nourishment and more significant anti-inflammatory benefits than most traditional carrier oils.
- Redness and Allergy Relief: Rich in rosmarinic acid and luteolin, it acts as a natural antihistamine for the skin, making it an ideal ingredient for those with rosacea, eczema, or seasonal skin allergies.
- Potent Antioxidant Protection: It contains high levels of polyphenols and Vitamin E, which neutralize free radicals caused by UV exposure and pollution, preventing "inflamm-aging."
- Collagen Preservation: Recent studies suggest that Perilla seed extract can inhibit collagenase (the enzyme that breaks down collagen), helping to maintain skin firmness and elasticity.
- Lightweight & Fast-Absorbing: Despite its high lipid content, it has a "dry oil" feel that penetrates the skin quickly without leaving a heavy or greasy residue.
