Ingredient review
Plukenetia Volubilis Seedcake
INCI: PLUKENETIA VOLUBILIS SEEDCAKE
A gentle, natural exfoliant from Sacha Inchi seeds that also provides antioxidant benefits, but research is limited.
In plain English
Plukenetia Volubilis Seedcake is the leftover material after oil is pressed from Sacha Inchi seeds. In skincare, it's ground into a fine powder and used as a physical exfoliant to gently buff away dead skin cells. It also contains natural antioxidants that may help protect the skin from environmental damage. Think of it as a mild, plant-based scrub ingredient that's less abrasive than some nut shell powders.

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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
The seedcake is the solid residue left after cold-pressing Sacha Inchi seeds to extract the oil. It's rich in fiber, protein, and residual antioxidants like tocopherols (vitamin E).
How it works
When ground into a fine powder, the seedcake particles physically exfoliate the skin's surface, helping to remove dead skin cells and unclog pores. The antioxidant compounds may also help neutralize free radicals, offering mild protection against oxidative stress.
Pros
Gentle exfoliation
The fine powder texture provides mild physical exfoliation, making it suitable for regular use without harsh abrasion.
Antioxidant boost
Residual antioxidants from the seed may help protect skin from environmental stressors like pollution.
Cons and cautions
Limited research
There are few peer-reviewed studies specifically on seedcake as a cosmetic ingredient, so its benefits are mostly anecdotal.
Potential allergen
As a seed-derived ingredient, it may cause reactions in people with seed or nut allergies.
Best for
- People looking for a natural, gentle exfoliant
- Those with normal to combination skin
Use caution if
- Individuals with very sensitive or broken skin
- Those allergic to nuts (Sacha Inchi is a seed, but cross-reactivity is possible)
Usage tips
Safety summary
Plukenetia Volubilis Seedcake is considered safe for topical use in rinse-off cosmetics. As with any physical exfoliant, avoid overuse to prevent skin irritation. Patch test if you have sensitive skin or seed allergies.
Research notes
Research on Sacha Inchi oil is more extensive than on the seedcake. The antioxidant content is inferred from the oil's known profile, but direct studies on seedcake in skincare are limited.
