Parachlorella Beijerinckii Exopolysaccharides

Parachlorella beijerinckii exopolysaccharides are complex carbohydrate polymers produced by a strain of freshwater microalgae. These molecules are extracted and used in skincare formulations for their film-forming and skin-conditioning properties.In cosmetic products, this ingredient functions primarily as a protective agent that creates a lightweight film on the skin's surface. This barrier can help reduce transepidermal water loss and provide a smoother feel, making it useful in moisturisers, serums, and protective products.

Exopolysaccharides are naturally occurring polymers that, when applied to skin, form a thin, adhesive layer. This film sits on the stratum corneum (the skin's outermost layer) and works mechanically rather than through chemical transformation.The protective layer created by these polysaccharides slows the rate at which water evaporates from the skin, which is particularly valuable in moisturising and barrier-support products. The film is also flexible enough to move with skin without feeling restrictive or heavy.

This ingredient is typically incorporated into moisturisers, serums, and barrier-repair products. It works well alongside humectants (such as glycerin) and occlusives (such as plant oils) to optimise hydration. Apply to clean skin morning or evening as part of your regular skincare routine. No special handling or timing restrictions apply.

Generally well-tolerated and suitable for most skin types, including sensitive skin. Algae-derived ingredients are not known to be common allergens, though patch testing is always advisable if you have a history of sensitivity to marine or botanical ingredients.
