Cucurbita Pepo Seed Extract
Unveil Formulate Labs' Cucurbita Pepo Seed Extract (INCI), an upcycled, bioactive proteic fraction from pumpkin seedcake, available as a standard or concentrated hydroglycerin stock. Rich in active peptides, amino acids, zinc, and essential fatty acids, this ingredient (also known by common names like pepita) supports the extracellular matrix and helps preserve dermal integrity for advanced anti-aging and firming formulations.
Upcycled seedcake extract
Botanical Identity: Derived from the pumpkin (*Cucurbita pepo*) seedcake, Formulate Labs' offering is the INCI Cucurbita Pepo Seed Extract, not supplier-specific SKUs or generalized trade names like Cucurbita pepo seed powder or pepita. This upcycled extract is a bioactive proteic fraction, exceptionally rich in amino acids, zinc, and essential fatty acids.
Dual mechanism: The active peptides within this extract support the extracellular matrix by boosting the synthesis of key structural proteins like collagen and fibrillin. Concurrently, it helps preserve the dermal matrix by downregulating the activity of matrix metalloproteinases (MMPs) and cathepsin L, enzymes known to contribute to dermal degradation.
Use levels: For Formulate Labs' Standard or Concentrated hydroglycerin stock, recommended use levels range from 1.0% to 10.0%. A typical use level to achieve clinical efficacy for anti-aging and firming benefits is 4.0%.
Market context: The peptide found in Elastonyl®-class actives is marketed specifically for firming and anti-stretch mark benefits, attributed to its ability to repair elastic fibers by inhibiting proteolytic enzymes. Suppliers like Provital, Greentech, and Codif position their plant-protein extracts as sustainable, upcycled alternatives to synthetic peptides, leveraging the clean beauty and circular economy trends. Brands such as Pravada Beauty Labs and Lotioncrafter frame similar ingredients as components in a smoothing multi-peptide complex intended for luxury firming creams, body treatments, and revitalizing eye serums.

Formulate Labs' Cucurbita Pepo Seed Extract is supported by peer-reviewed research demonstrating its efficacy in addressing visible signs of aging, supporting skin integrity, and providing photoprotective benefits. 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.
This study shows the extract helps ameliorate visible signs of aging related to oxidative stress in cellular models. Its ability to increase alkaline phosphatase (ALP) activity suggests a role in supporting overall cellular health and skin integrity.
In a wound-healing model, pumpkin seed fractions demonstrated support for the skin's natural repair process, promoting complete re-epithelialization and more organized collagen fiber networks. This action is beneficial for improving skin texture and the appearance of firmness.
This research confirms that the extract has significant photoprotective properties, helping to shield the skin from UVB radiation. By suppressing over 22% of UVB, it aids in preventing the premature appearance of photoaging, such as fine lines and wrinkles.

Bulk composition at the selected Cucurbita Pepo Seed 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-CPS-W1-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.
