What Is Sacha Inchi Seed Oil?
Sacha inchi seed oil is cold-pressed from the seeds of Plukenetia volubilis, an Amazonian plant known as the Inca peanut. Globally recognized for its exceptional omega-3 content, robust tocopherol (Vitamin E) concentration, and ultra-light sensory profile, it is considered one of the plant world’s most polyunsaturated carrier oils.
With a total unsaturate content of approximately 88–93% and a rare omega-3 to omega-6 ratio of ~1.3:1, sacha inchi seed oil absorbs extremely rapidly, leaves a silky dry-oil finish, and is well-suited for formulas focused on nourishment, skin comfort, and a healthy-looking complexion. Its non-comedogenic rating of 0–1 makes it appropriate for all skin types, including oily and acne-prone skin.

Skin Benefits
The following describes cosmetic properties based on ingredient research and traditional formulation use — not medical claims.
Nourishment & Skin Comfort
The exceptional omega-3 and omega-6 content, combined with phytosterols, contributes to a deeply nourishing, comfortable skin feel. Sacha inchi seed oil is commonly used in formulas designed to help skin look and feel moisturized, soft, and comfortable — even on very dry or delicate-feeling skin.
Support for a Calming Skin Feel
Alpha-linolenic acid (omega-3, 44–55%) and phytosterols (β-sitosterol, stigmasterol, campesterol) contribute to a calming sensory experience on reactive or environmentally-stressed skin. Sacha inchi seed oil is often included in formulas designed to help skin look and feel calmer and more comfortable.
Antioxidant-Rich Care
With 176–226 mg/100g of tocopherols — predominantly γ-tocopherol and δ-tocopherol — plus carotenoids and polyphenols, sacha inchi seed oil provides a high-potency antioxidant profile associated with the appearance of a healthy, radiant-looking complexion and protection from environmental stressors.
Support for the Appearance of Mature-Looking Skin
Tocopherols, carotenoids, and essential fatty acids contribute to antioxidant-rich care associated with the appearance of smoother, more supple, and more radiant skin. Sacha inchi seed oil is commonly used in formulas targeting the appearance of dry fine lines and dullness in mature-looking skin.
Non-Comedogenic & Skin Feel Balance
With a comedogenic rating of 0–1, sacha inchi seed oil will not clog pores and is well-suited for oily or acne-prone skin. Its high linoleic acid content is associated with a balanced, comfortable skin feel in cosmetic research.
Hair & Scalp
Lightweight and fast-absorbing; moisturizes dry ends without weighing hair down, supports scalp comfort, and nourishes with essential fatty acids and tocopherols. Suitable for use in hair masks, scalp serums, and conditioning treatments.

Unsaponifiables & Bioactives
Tocopherols / Vitamin E (176–226 mg/100g)
Predominantly γ-tocopherol and δ-tocopherol, plus α-tocopherol. Among the highest tocopherol concentrations of any carrier oil — powerful antioxidant protection and oxidative stability.
Phytosterols
β-sitosterol, stigmasterol, campesterol, Δ5-avenasterol. Support a calming skin feel and contribute to the appearance of comfortable, nourished skin.
Carotenoids & Polyphenols
Associated with antioxidant protection and the appearance of a more even, luminous complexion. Contribute to the oil’s pale green color.
Minor Bioactives

- Apply water-based serums (if using)
- Dispense 2–4 drops into palm
- Warm between hands and press gently into face, neck, or body
- Follow with moisturizer (optional) or use as final step
- Morning: Apply before sunscreen — absorbs extremely quickly and won’t interfere with SPF
- Evening: Use as final step or mix 1–2 drops into night cream
- Body use: Excellent for dry, delicate-feeling, or mature skin; apply to damp skin after bathing

Formulation Notes
| Use Level | 1–15% in serums, creams, and balms; up to 100% as a standalone facial, body, or scalp oil |
| Blending | Pairs well with stable oils (meadowfoam, jojoba, squalane) to improve oxidative stability and extend shelf life |
| Heat | Add at cool-down phase (below 35°C) to preserve omega-3 fatty acids and tocopherols |
| Stability | Moderate — high PUFA content increases oxidation risk; high tocopherol/carotenoid content provides strong natural resistance. Add vitamin E at 0.1–0.5% to further extend shelf life |
| Layering | Layers well with vitamin C serums, peptide serums, and botanical actives; apply oil after water-based actives |
| Packaging | Dark glass preferred; store airtight, cool, and dark; refrigerate after opening |
Storage & Shelf Life
| Shelf Life | Moderate; use within recommended timeframe and refrigerate after opening |
| Storage | Airtight, cool, low light; refrigerate after opening strongly recommended |
| Stability | Moderate — very high PUFA content increases oxidation risk; add vitamin E at 0.1–0.5% and blend with stable oils to extend shelf life |
