Chlorella Vulgaris/Lupinus Albus Protein Ferment

Chlorella vulgaris and lupinus albus protein ferment is a composite ingredient created by fermenting proteins derived from chlorella (a freshwater microalga) and lupinus albus (white lupin, a legume). Fermentation breaks down these plant proteins into smaller, more bioavailable molecules that the skin can more readily utilise.In skincare formulations, this ingredient functions primarily as a skin conditioner and protective agent. It works to support the skin's natural barrier function and help maintain hydration levels, making it a suitable choice for formulations targeting barrier health a…

The fermented protein molecules are smaller than their unfermented counterparts, allowing them to penetrate or adhere more effectively to the skin's surface. Once there, they form a conditioning layer that helps lock in moisture and reinforce the lipid barrier.The amino acid profile of these plant proteins also supports the skin's natural moisturising factor (NMF) — compounds that help the stratum corneum retain water. By replenishing these amino acids topically, the ingredient helps sustain hydration and barrier integrity.

This ingredient is typically found in moisturisers, serums, and barrier-repair products. Apply to clean skin, either alone or layered with other treatments. It works well in both morning and evening routines. If using in a serum or essence, apply before heavier creams to allow the fermented proteins to make contact with the skin.

Generally well-tolerated across skin types. Those with sensitivities to legumes or algae should patch-test first, though sensitisation risk is low in cosmetic concentrations. No significant cautions reported in standard use.
