Marine Plankton Extract — Lifting & Tightening
INCI: Plankton Extract (CAS 91079-57-1 · EINECS 293-445-7)
A marine active of French origin, rich in high molecular weight polysaccharides. In the ocean these polymers are what plankton produce to shield themselves and hold nutrients close in a demanding environment; on skin, the same polysaccharides form a light, cohesive film across the surface.
That film is what delivers the tightening effect — an immediate, temporary lift as it dries and contracts, smoothing the appearance of fine lines at the epidermal surface. It is a physical, surface-level effect rather than a biological one, which makes it well suited to instant-result formats: eye treatments, firming serums, masks and ‘flash lift’ products where the result should be felt straight away.
Pairs well with longer-acting actives — peptides, niacinamide, plant cell culture extracts — where the plankton delivers the immediate sensory result and the other actives do the slower work.
Add to the cool-down phase. For external use in cosmetic formulation only. Not for internal use.
