We verify all information on this page using publicly available nomenclature standards from The Personal Care Products Council (PCPC), the European Commission's CosIng database and documentation provided directly by ingredient manufacturers. Our analysis is based on technical data from these sources to ensure accuracy and reliability.

What Is Phormidium Elemis Lysate Filtrate?

Phormidium Elemis Lysate Filtrate comes from Phormidium elemis, a blue-green alga that thrives in mineral-rich aquatic settings. Scientists discovered that when the cells of this microalga are gently broken apart, or lysed, they release a mix of proteins, peptides, vitamins and sugars with skin-friendly properties. The liquid left after this process is filtered to remove cell debris, leaving a clear filtrate full of bioactive compounds.

The use of algal extracts in skincare rose in popularity during the late 1990s when formulators began looking for sustainable plant and marine sources of antioxidants. Phormidium Elemis Lysate Filtrate joined the lineup as testing showed it could hydrate and protect skin against everyday environmental stress. Manufacturing starts with controlled tank cultivation of the alga to avoid pollutants. Once harvested, the biomass is lysed through gentle mechanical or enzymatic means, then passed through fine filters to collect the water-based filtrate that goes into cosmetic blends.

You will most often find this ingredient in lightweight moisturizers, anti-aging serums, sheet masks and after-sun treatments where its hydrating and antioxidant qualities add value without a greasy feel.

Phormidium Elemis Lysate Filtrate’s Cosmetic Benefits/Uses

This multitasking ingredient supports skin health and product performance in several ways:

  • Antioxidant – Helps neutralize free radicals generated by UV light and pollution, which can lead to dullness and early fine lines. Including antioxidants in a formula can boost its protective claims and appeal to users seeking preventive skincare.
  • Humectant – Draws water from the environment and deeper skin layers toward the surface, delivering a quick hit of moisture and giving skin a plumper, smoother look. Humectants also improve spreadability so the product glides on easily.
  • Skin Conditioning – Supplies nutrients and soothing molecules that leave skin feeling soft and balanced. This enhances overall sensory experience, making the product feel more luxurious and comforting.

Who Can Use Phormidium Elemis Lysate Filtrate

This ingredient suits most skin types, including dry, normal, combination and oily skin, because it hydrates without leaving a heavy or occlusive film. Sensitive skin generally tolerates it well thanks to the gentle nature of algal extracts, but anyone with a known algae or marine allergy should proceed cautiously as a precaution.

Phormidium Elemis Lysate Filtrate is derived from microalgae grown in controlled tanks and involves no animal-derived materials, so it is considered appropriate for both vegans and vegetarians.

No data links this filtrate to hormonal disruption, so products containing it are typically seen as safe for people who are pregnant or breastfeeding. That said, this is not medical advice and pregnant or nursing users should have their healthcare provider review any new skincare product before adding it to their routine.

The ingredient does not increase the skin’s sensitivity to sunlight, so it is not classed as photosensitising. Normal daily sun protection practices remain recommended for overall skin health.

Potential Side Effects/Adverse Reactions

Responses to topical Phormidium Elemis Lysate Filtrate differ from person to person. The points below outline potential reactions yet these are uncommon when the ingredient is properly formulated and used as directed.

  • Mild redness or stinging may appear in individuals with very reactive or compromised skin barriers
  • Allergic contact dermatitis could develop in those who have an uncommon sensitivity to algae-derived proteins
  • Eye irritation if the product accidentally gets into the eyes, especially in higher concentration serums
  • Interaction with over-exfoliated skin where existing irritation may be temporarily intensified

Discontinue use and consult a medical professional if any persistent discomfort or visible irritation occurs.

Comedogenic Rating

Rating: 0/5. Phormidium Elemis Lysate Filtrate is water based, oil free and lightweight so it does not clog pores or leave residue that could trap dead skin cells. Its humectant molecules draw water rather than sebum to the surface which further reduces any risk of congestion.

Suitable for acne-prone or breakout-prone skin.

No published data suggest it worsens comedogenicity when blended with other common cosmetic ingredients, but the final formula always matters so check the overall product if you are highly sensitive.

Summary

Phormidium Elemis Lysate Filtrate works as an antioxidant that defuses free radicals, a humectant that pulls moisture into the upper layers of skin and a skin conditioner that smooths and softens through its mix of peptides, vitamins and sugars. These actions help maintain a fresh, comfortable complexion.

The ingredient is gaining traction in modern moisturizers and serums, especially in brands that emphasize marine sourcing and eco conscious formulas, though it is not yet as ubiquitous as classic aloe or hyaluronic acid.

Current safety data show a very low risk profile with minimal irritation or allergy reports, making it suitable for most people. As with any new skincare addition, perform a quick patch test to confirm personal tolerance.
