What Is Parachlorella Beijerinckii Exopolysaccharides?
Parachlorella Beijerinckii Exopolysaccharides are long-chain sugars that come from the microalgae Parachlorella beijerinckii. These sugars are released by the algae during a controlled fermentation process, then collected and purified for skincare use. Although algae have been studied for decades, interest in their protective sugars grew in the past few years as brands looked for plant based alternatives to synthetic film formers. Today laboratories cultivate the microalgae in closed tanks, feed them a nutrient mix, let them ferment and finally separate the clear exopolysaccharide solution from the biomass. After filtration and drying, the powder is ready for use in cosmetic formulas.
You will most often see Parachlorella Beijerinckii Exopolysaccharides in sheet masks, hydrating serums, soothing gels, anti-aging creams and protective lotions where a light, flexible film on the skin is desired.
Parachlorella Beijerinckii Exopolysaccharides’s Cosmetic Benefits/Uses
In skincare these algae derived sugars serve more than one purpose and can improve both feel and performance of a product.
- Film forming: Creates a thin breathable layer that locks in moisture, smooths skin surface and gives a soft finish
- Skin protecting: Shields the skin from daily environmental stress such as pollution or dry air helping reduce irritation and transepidermal water loss
Who Can Use Parachlorella Beijerinckii Exopolysaccharides
This algae derived sugar is considered gentle enough for all skin types. Dry and mature skin benefit from its moisture sealing film while oily and combination skin appreciate the lightweight feel that does not add extra grease. Sensitive or redness prone complexions can also tolerate it well thanks to its soothing protective action. It is not known to trigger acne or clog pores.
Because it is sourced from microalgae and processed without animal derivatives, the ingredient is suitable for both vegetarians and vegans.
No specific warnings exist for pregnant or breastfeeding women. The large sugar molecules remain on the surface and are not expected to enter the bloodstream. Still this is not medical advice and anyone who is pregnant or nursing should show the full product ingredient list to a healthcare professional before use just to be safe.
Parachlorella Beijerinckii Exopolysaccharides are not photosensitizing so they will not make skin more prone to sunburn. The ingredient also plays well with common actives like retinol, vitamin C and exfoliating acids without reducing their effect.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Parachlorella Beijerinckii Exopolysaccharides can vary from person to person. The points below cover potential reactions yet they are uncommon when the ingredient is used at recommended levels in a well formulated product.
- Mild redness or stinging in individuals with an algae allergy
- Transient tight feeling if the finished product forms too thick a film
- Rare contact dermatitis triggered by residual ferment by-products
- Product pilling when layered over heavy silicone primers which can cause mechanical irritation
If any irritation or unexpected reaction occurs stop using the product immediately and consult a qualified healthcare provider.
Comedogenic Rating
Rating: 0 (non comedogenic). The large, water soluble sugar chains stay on the surface, create a breathable film and rinse away easily without blocking pores. They add no extra oil or wax so they do not feed acne-causing bacteria. Suitable for skin that breaks out easily. Only the overall formula matters; if the product also contains heavy oils that could change how it behaves on very clog-prone skin.
Summary
Parachlorella Beijerinckii Exopolysaccharides act mainly as a film former and skin protectant. Their long sugar chains spread into a lightweight veil that locks in moisture, smooths texture and helps defend against pollution and dehydration. Brands are increasingly interested in these algae sugars as a plant based alternative to synthetic polymers, yet they are still more of a rising star than a mainstream staple so you may spot them in select serums, masks and creams rather than every shelf.
Overall safety is high; the molecules are too large to penetrate deeply and reports of irritation are rare. As with any new cosmetic, patch testing is a smart step so you can confirm personal compatibility before full-face use.
