What Is Evening Primrose Oil?
Evening Primrose Oil (EPO) is cold pressed from the seeds of Oenothera biennis. It is renowned for its unusually high essential fatty acid content (linoleic and gamma-linolenic acid), excellent anti-inflammatory benefits, and gentle, rapidly absorbing skin feel.
EPO is a top-tier omega-6-rich specialty oil delivering feather-light hydration, deep barrier restoration, and, through its high GLA content, potent anti-inflammatory and skin-calming effects. Beautifully suited for non-greasy, acne-prone, and mature skin, EPO offers powerful functional and sensory benefits for modern bath and body care, as well as premium evidence-based skincare.
Fatty Acid Profile: Linoleic + Gamma-Linolenic Acids
Evening Primrose Oil's effectiveness comes from its exceptional omega-6 fatty acid composition, particularly its high GLA content—one of the few plant oils to naturally contain this therapeutic fatty acid:

Complete Fatty Acid Composition
- Linoleic Acid (Omega-6, C18:2): 65–75% — Essential for barrier repair, anti-inflammatory, moisture retention
- Gamma-Linolenic Acid (GLA, Omega-6, C18:3): 9–11% — Potent anti-inflammatory, barrier restoration, healing, calming
- Oleic Acid (Omega-9, C18:1): 5–11% — Softening, penetration enhancement
- Palmitic Acid (C16:0): 5–8% — Texture support, mild occlusivity
- Stearic Acid (C18:0): 1–3% — Structure, firmness
- Arachidic Acid (C20:0): 2% max — Moisturizing, lightness
- Eicosenoic Acid (Omega-9, C20:1): 2% max — Ultra-trace levels
- Alpha-Linolenic Acid (Omega-3, C18:3): 0.5% — Trace anti-inflammatory support
Why This Matters: The combination of high linoleic acid (65-75%) and GLA (9-11%) creates a powerful omega-6 profile that delivers deep hydration, barrier support, and sebum control—especially for dry, sensitive, and problem skin. GLA is a direct precursor to prostaglandins that support skin repair and calm inflammation.
Bioactive Compounds: Beyond Fatty Acids
Evening Primrose Oil is rich in skin-active compounds that enhance its barrier-repairing and anti-inflammatory properties:

- Unsaponifiable Fraction: 1-2% total — Higher than many oils, providing additional skin benefits
- Sterols: 27% of unsaponifiables, mainly β-sitosterol and stigmasterol — Barrier protection, anti-inflammatory
- Fatty Alcohols: ~13% including 1-tetracosanol, 1-hexacosanol — Skin soothing, emollient
- Squalene: ~5% — Antioxidant, healing, skin-identical lipid
- Tocopherols (Vitamin E): α: (7mg/kg), γ: (187mg/kg), δ: (15mg/kg) — Decent antioxidant benefit, γ-tocopherol dominant
- Phenolic Acids: Small amounts — Antioxidant, soothing benefit
- Other Vitamins/Minerals: Traces of A, B, C, E, calcium, potassium, magnesium
Skin Benefits: What Evening Primrose Oil Does
Intensive Barrier Repair & Deep Hydration
EPO's omega-6 rich profile (linoleic + GLA) delivers deep hydration, barrier support, and sebum control—especially for dry, sensitive, and problem skin. GLA is a direct precursor to prostaglandins that support skin repair and calm inflammation, making EPO ideal for barrier restoration and preventing TEWL (trans-epidermal water loss).

Potent Anti-Inflammatory & Calming
The high GLA content (9-11%) and high linoleic acid profile work together to visibly reduce redness, swelling, dry skin, and flare-ups. EPO is excellent for eczema, psoriasis, dermatitis, rosacea, and acne, providing powerful anti-inflammatory and skin-calming effects.
Eczema, Psoriasis & Dermatitis Support
EPO's anti-inflammatory and barrier-repairing properties make it exceptionally effective for inflammatory skin conditions. The GLA content helps calm irritation, reduce flare-ups, and support skin healing in eczema, psoriasis, and dermatitis.
Moisturizing, Plumping & Anti-Aging
EPO's high linoleic acid and GLA content soften skin, promote a more radiant complexion, and reduce roughness. It supports collagen synthesis, improves firmness, and provides moisturizing benefits that leave skin soft and plump.
Sebum Regulation & Acne Support
The high linoleic acid content and GLA regulate oil production and unclog pores, making EPO ideal for acne-prone skin. It balances sebum without causing breakouts, providing hydration while supporting clear skin.
Wound Healing & Skin Repair
EPO speeds repairing of minor wounds, scars, and irritation. The GLA and antioxidant/polyunsaturated content help even skin tone and brighten the complexion, supporting overall skin health and repair.
Gentle for Sensitive Skin
EPO's feather-light, non-greasy texture and anti-inflammatory properties make it suitable for use in baby/children's products, after-sun, and sensitive formulas. It's gentle enough for the most reactive skin types.
