Hydrolyzed Pumpkin Seedcake

Hydrolyzed pumpkin seedcake is a plant-derived ingredient created by breaking down the protein-rich residue left after pumpkin seed oil extraction. The hydrolysis process breaks these proteins into smaller peptide chains, making them more suitable for cosmetic formulation and potentially easier for the skin to utilise.In skincare, this ingredient functions as a skin protectant. The peptides it contains can form a protective film on the skin surface, helping to support the skin's natural barrier and reduce transepidermal water loss (TEWL).

Hydrolyzed pumpkin seedcake contains amino acids and small peptide chains that deposit onto the skin surface. These peptides form a lightweight occlusive layer, similar to other plant-derived proteins used in skincare, which helps prevent moisture evaporation and supports barrier integrity.The ingredient also contains natural compounds present in pumpkin seeds, such as tocopherols and fatty acids, which may contribute minor protective and conditioning effects.

This ingredient is typically found in moisturisers, serums, and hydrating products. It works well as part of a layered routine and can be used alongside other hydrating or protective ingredients. If incorporating a new product containing this ingredient, introduce it gradually to monitor how your skin responds.

Generally well-tolerated in most formulations. Those with specific seed allergies or sensitivities should review full product ingredient lists, though topical use is typically lower-risk than ingestion.
