What Is Auxenochlorella Protothecoides Lysate Filtrate?
Auxenochlorella Protothecoides Lysate Filtrate comes from a freshwater microalga called Auxenochlorella protothecoides. When the algae cells are gently broken down, or lysed, the inner goodies like proteins, amino acids, sugars, vitamins and minerals are released. The mix is then filtered to remove cell debris, leaving a clear liquid that is easy to add to creams and serums.
Interest in microalgae for beauty soared in the early 2000s as brands searched for plant based actives with a smaller environmental footprint. Auxenochlorella stood out for its fast growth and nutrient packed profile. Labs soon learned that breaking the cells apart made these nutrients more available to skin, which led to its debut in anti aging and hydrating formulas.
The process starts with controlled tank cultivation where light, nutrients and temperature are monitored for optimal growth. The harvested algae is then mechanically or enzymatically lysed, followed by fine filtration to ensure purity. The resulting filtrate is stable, water soluble and has a light green tint.
You will most often spot Auxenochlorella Protothecoides Lysate Filtrate in daily moisturizers, firming serums, sheet masks, eye creams, after sun gels and specialty treatments aimed at boosting radiance or improving skin texture.
Auxenochlorella Protothecoides Lysate Filtrate’s Cosmetic Benefits/Uses
This ingredient is prized for one main function in skincare.
Skin conditioning: The filtrate coats the skin with a thin, breathable film that pulls in and holds moisture, helping dry or tired skin feel softer and look smoother. Its natural proteins and sugars support the skin barrier, while vitamins and antioxidants help fend off dullness caused by everyday stressors. Regular use can leave skin looking more supple and refreshed.
Who Can Use Auxenochlorella Protothecoides Lysate Filtrate
This marine derived filtrate is generally well tolerated by all skin types, including dry, oily, combination and sensitive skin. Its water based nature means it feels light on the skin and does not usually clog pores, so acne prone users can incorporate it without much worry. There are no known reasons for those with very reactive or redness prone skin to avoid it, although an individual allergy to algae is always possible.
Because the ingredient is sourced from microalgae and no animal by products are involved in its production, it is suitable for both vegans and vegetarians.
No data links Auxenochlorella Protothecoides Lysate Filtrate to problems during pregnancy or breastfeeding. That said this is not medical advice and anyone who is pregnant or nursing should run any skincare product they plan to use past a qualified healthcare professional to be on the safe side.
The filtrate does not increase photosensitivity, so there is no special need to alter sun protection habits beyond normal daily SPF use. It also plays well with common actives like niacinamide, hyaluronic acid and gentle exfoliating acids, making it easy to slot into most routines.
Potential Side Effects/Adverse Reactions
Side effects and reactions to the topical application of Auxenochlorella Protothecoides Lysate Filtrate can vary from person to person. The following list covers potential issues, but they are uncommon when the ingredient is properly formulated and used as directed.
- Mild temporary redness or warmth often linked to overall formulation rather than the filtrate itself
- Itching or tingling in individuals with an existing algae or seafood allergy
- Contact dermatitis presenting as localized rash or bumps in rare cases of sensitivity
- Breakouts if the finished product also contains heavy occlusive oils and the user has very clog prone skin
- Eye irritation if the product accidentally gets into the eyes during application
If any negative reaction occurs stop using the product immediately and consult a healthcare professional.
Comedogenic Rating
Rating: 0 / 5. Auxenochlorella Protothecoides Lysate Filtrate is a water based extract that contains mostly proteins, amino acids and sugars with virtually no heavy oils or waxes, so it does not create the kind of surface film that can trap dead cells inside pores. Laboratory data and supplier literature report no pore clogging tendency, and real world use in lightweight gels and serums backs this up.
Suitable for acne prone skin thanks to its non greasy nature and low molecular weight components that rinse away easily.
Keep in mind that finished products may pair the filtrate with richer emollients. If breakouts develop look at the full ingredient list rather than blaming the filtrate itself.
Summary
Auxenochlorella Protothecoides Lysate Filtrate is mainly a skin conditioning agent that pulls moisture to the surface, reinforces the barrier with natural proteins and delivers vitamins and antioxidants that brighten a dull complexion. Its water solubility lets it sink in fast without residue, leaving skin feeling supple and refreshed.
The ingredient enjoys modest popularity in K beauty style hydrators and sheet masks but has yet to hit mainstream status, partly because microalgae extracts are still a niche marketing story outside dedicated skincare circles.
Safety studies rate it as low risk for irritation or sensitization and it carries a comedogenic rating of zero, making it friendly for nearly all skin types including sensitive and acne prone. As with any new skincare product it is wise to do a quick patch test to rule out personal allergies before applying it to the entire face.
