What it is
A natural extract derived from the seedcake (the solid residue left after oil extraction) of the European plum (Prunus domestica). It contains a mix of polyphenols, flavonoids, and fatty acids.
How it works
The polyphenols and flavonoids in plum seedcake extract act as antioxidants, neutralizing free radicals that can damage skin cells. The residual fatty acids provide light emollient effects, helping to soften and smooth the skin's surface.
Pros
Gentle antioxidant support
Plum seedcake extract helps defend skin from daily oxidative stress without causing irritation, making it a good choice for sensitive skin types.
Lightweight hydration
Unlike heavier oils, this extract provides a subtle moisturizing effect that won't clog pores or feel greasy, ideal for layering under sunscreen or makeup.
Cons and cautions
Limited research
Most evidence for plum seedcake extract comes from lab studies, not large human trials, so its exact benefits in skincare are not fully proven.
Potential allergen
Though rare, people with stone fruit allergies may experience a reaction, so patch testing is recommended before widespread use.
Best for
- People looking for a gentle antioxidant to add to their routine
