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.
