What it is

A natural extract made from the solid residue (seedcake) left after pressing quinoa seeds for oil. It contains proteins, peptides, and antioxidants that can benefit the skin.

How it works

It provides a film-forming effect that helps retain moisture and may reduce visible redness by calming the skin's surface. The peptides in the extract can also support the skin's natural repair processes.

Pros

Derived from a byproduct of quinoa oil production, appealing to those seeking sustainable, plant-based skincare ingredients.

Cons and cautions

Most evidence comes from lab studies or small trials; large-scale human studies confirming its benefits are still lacking.

Modest efficacy

Compared to well-studied soothing agents like niacinamide or panthenol, its calming effects may be less pronounced.

Best for

  • Those looking for a gentle, natural soothing ingredient

Use caution if

  • Individuals with a known allergy to quinoa or related plants

Usage tips

Use in a serum or moisturizer formulated for sensitive skin.
