The extract

The Science Behind Cucurbita Pepo Seed 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' 5% 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.

Pricing context: Publicly available B2B pricing for specialized, cosmetic-grade protein hydrolysates is sparse. While raw, food-grade pumpkin protein is a commoditized ingredient, advanced cosmetic extracts command a premium based on purity, molecular weight profile, and efficacy data. Formulate Labs offers competitive pricing, with a sample (500 g) at $230.00, standard (1 kg) at $350.00, and bulk (17 kg) at $297.50 / kg.

Published research

Peer-reviewed literature for due diligence.

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.

Oxidative Stress & Cellular Health

Oh, J. et al.

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.

Skin Repair & Collagen Organization

Bardaa, S. et al.

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.

Photoprotective Properties

Nakavoua, A. et al.

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.
