Ingredient review
Plukenetia Volubilis Seed Extract
INCI: PLUKENETIA VOLUBILIS SEED EXTRACT
A gentle, omega-rich seed extract that helps nourish and protect the skin barrier without clogging pores.
In plain English
This extract comes from the seeds of the sacha inchi plant, a rainforest vine native to the Amazon. It's packed with omega-3, omega-6, and omega-9 fatty acids, plus vitamin E and other antioxidants. When applied to skin, it helps replenish moisture, support the skin barrier, and defend against environmental damage. Because it's non-greasy and low on the comedogenic scale, it works well for many skin types, including oily and acne-prone skin.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A cold-pressed or solvent-extracted oil from the seeds of Plukenetia volubilis, also known as sacha inchi or Inca peanut. The oil is rich in alpha-linolenic acid (an omega-3), linoleic acid (an omega-6), and tocopherols (vitamin E).
How it works
The fatty acids in sacha inchi seed extract mimic the skin's natural lipids, helping to reinforce the moisture barrier and reduce water loss (transepidermal water loss, or TEWL). The antioxidants, especially vitamin E, neutralize free radicals that can cause premature aging. Its lightweight texture allows it to absorb quickly without leaving a heavy residue.
Pros
Rich in omega-3s
Sacha inchi seed extract is one of the few plant sources high in alpha-linolenic acid (omega-3), which helps calm inflammation and support a healthy skin barrier.
Lightweight feel
Unlike some heavy oils, this extract absorbs quickly and doesn't leave a greasy film, making it comfortable for daytime use under makeup or sunscreen.
Cons and cautions
Limited research
While the fatty acid profile is promising, there are few peer-reviewed studies specifically on sacha inchi seed extract in topical skincare, so evidence is mostly theoretical.
Potential allergen
As a seed-derived ingredient, it may trigger allergic reactions in people with seed or nut allergies. Always patch test if you have known sensitivities.
Best for
- People with dry or dehydrated skin looking for a lightweight oil
- Those with sensitive or reactive skin who want a gentle, nourishing ingredient
Use caution if
- Individuals with a known allergy to sacha inchi seeds or tree nuts should patch test first
Usage tips
Safety summary
Sacha inchi seed extract is considered safe for topical use with a low irritation and comedogenic risk. As with any plant extract, rare allergic reactions are possible, so patch testing is recommended for those with seed allergies.
Research notes
Research on sacha inchi oil focuses on its nutritional and anti-inflammatory properties when consumed orally. Topical evidence is limited but supported by the well-documented benefits of its constituent fatty acids and vitamin E for skin barrier function and antioxidant protection.
