Fucus Vesiculosus Extract
Formulate Labs offers Fucus Vesiculosus Extract in a standard or concentrated hydroglycerin stock solution, rich in key actives like polysaccharides, phlorotannins, and fucoxanthin, providing formulators the pure INCI active without supplier-specific trade-name complexities.
From the rich depths of brown seaweed
Derived from the brown seaweed *Fucus vesiculosus*, commonly known as bladderwrack, this extract is often referenced in the market as **Fucus vesiculosus powder** or **brown seaweed**. Formulate Labs provides the pure **INCI name: Fucus Vesiculosus Extract**, ensuring formulators receive the specific active, not a supplier's proprietary blend or SKU.
Dual mechanism: **Fucus Vesiculosus Extract** supports skin's structural integrity by promoting fibroblast-populated collagen gel contraction through enhanced integrin expression, contributing to a firming and toning appearance, while also preserving the dermal matrix by inhibiting collagenase and elastase. Its constituent polysaccharides, notably alginic acid and fucoidans, form a non-occlusive, moisture-binding film on the skin's surface, helping to reduce transepidermal water loss (TEWL) and support skin hydration. Rich in phlorotannins and fucoxanthin, the extract also provides potent free-radical scavenging benefits, downregulates tyrosinase activity for a brightening effect, and inhibits hyaluronidase to maintain the skin's natural hyaluronic acid content.
Use levels: Formulate Labs offers this active as a Standard or Concentrated hydroglycerin stock solution. Recommended application rates for this specific stock solution are typically 1% in facial anti-aging formulations and 5–10% in body firming products to achieve desired cosmetic effects.
Market context: Formulate Labs provides the pure INCI active, offering formulators direct access to the core components found in various trade-name materials. This allows for greater flexibility and control in formulation design, contrasting with market offerings like 'Liporeductyl-class actives' often positioned for body care (cellulite appearance, microcirculation), 'Phytoliquid Fucus-class actives' marketed within 'clean beauty' (revitalizing, moisture-binding botanicals), and 'FSS Phytogel PF-class actives' positioned as sustainable film-formers and viscosity modifiers (protective matrix, alternative to animal gelatin).
We ship standard or concentrated extract stock with selectable preservation - ready to meter into finished formulas at the use rates in the formulation guide below.*
Formulate Labs offers the pure INCI active, distinct from various market trade-name materials (Liporeductyl-class actives, Phytoliquid Fucus-class actives, FSS Phytogel PF-class actives).

Scientific research highlights the multifaceted cosmetic benefits of Fucus Vesiculosus Extract. Clinical studies demonstrate its efficacy in improving skin elasticity and reducing skin thickness, contributing to a more toned appearance. Further investigations have identified key bioactives, such as fucoxanthin and phlorotannins, which are responsible for its significant antioxidant, brightening, and hydrating properties through mechanisms like tyrosinase and hyaluronidase inhibition. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.
Topical application of a 1% aqueous extract for five weeks measurably decreased cheek skin thickness and improved elasticity, suggesting support for a more toned, firm, and structurally sound skin appearance.
Identifies fucoxanthin and phlorotannins as key bioactives providing significant antioxidant benefits, inhibiting tyrosinase and hyaluronidase to support skin brightness and hydration.
The phlorotannins within the extract demonstrate robust free-radical scavenging capabilities, functioning as effective cellular protectors against oxidative stress.

Bulk composition at the selected Fucus Vesiculosus Extract loading. Base carrier components scale proportionally when preservative is added; extract stays at the selected loading. Updates dynamically when you change base or preservation above. Full CAS disclosure is on the SDS/TDS for the selected variant (FL-FUV-W2-MBS4-5PCT-001).
SDS + TDS are issued per selected recipe. Links swap when you change selections above. A sample COA shows the standard extract QC panel (pH, organoleptic, TAMC/TYMC). Lot-specific COAs ship with every order.
We cook the raw botanical powder into the selected carrier. The botanical carries polar phenolics, flavonoid glycosides, and related extractable fractions. Those markers support antioxidant and skin-conditioning cosmetic stories. This is not a solvent isolate or a standardized marker extract. Lot identity appears on the COA and TDS.
This is a ready-to-use cosmetic extract stock, not a finished consumer product and not a standardized marker isolate. We cook the raw botanical powder into the selected hydroglycerin or oil carrier. Aqueous lots are released on pH, organoleptic, TAMC, and TYMC (total counts only). Oil macerates are released on organoleptic only. A sample COA is on this page; the lot-specific COA ships with the order.
