Science
Mechanism of Action
As a peptide, this extract works to significantly increase dermal density, initiating skin restructuring that both smooths the skin's surface and diminishes the appearance of wrinkles. It achieves this by upregulating genes crucial for Extracellular Matrix (ECM) organization and repair, such as Connective Tissue Growth Factor (CTGF) and FOXO3. This biological action promotes healthy cell adhesion, migration, and proliferation, facilitating the proper alignment of collagen and elastin fibers within the dermal matrix to repair and prevent dermal elastosis.

Key findings
- 01 A clinical study utilizing a product containing NaturePep® Sacha Inchi (Hydrolyzed Plukenetia Volubilis Seed Extract) demonstrated a 45% reduction in facial sagginess over 28 days. The study also reported a decrease in skin roughness by over 20% across three distinct parameters within 21 days.

The Formula
Formulation
Stability
For optimal stability in emulsion formulations requiring heat, it is recommended to incorporate this ingredient during the cooling phase, specifically when the temperature drops below 40°C (104°F), and after the emulsion has fully formed. It should always be incorporated into a formulation, not applied directly to the skin.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet evaluated this ingredient. While 'HYDROLYZED PLUKENETIA VOLUBILIS SEED EXTRACT' is listed as 'RESTRICTED' for EWG VERIFIED products without adequate substantiation, EWG notes general concerns regarding the P. volubilis plant itself, including recorded allergic reactions (some severe) and potential in vitro hepatotoxic effects from certain P. volubilis substances. Although general references to 'Carcinogenic to humans' are cited, EWG's specific score for 'Cancer' for this ingredient is 'No Data'. Hydrolyzed vegetable proteins are generally approved as food additives by the FDA. In vitro studies have indicated no cytotoxic effects from P. volubilis seeds at concentrations up to 400 μg/mL in specific cell lines.
