What Palmitoyl Pentapeptide-4 Is
Palmitoyl pentapeptide-4 is a small peptide (PubChem CID 9897237) built from a fatty acid chain attached to a short amino acid sequence. It is manufactured as a cosmetic ingredient rather than a systemic drug. The label classifies the product under a non-standardized allergenic extract category, which reflects how the filing was coded rather than a pharmacological drug class.
What Palmitoyl Pentapeptide-4 Is Approved For
The label covers a single product, a Stretch Marks cream, intended to reduce the appearance of scars and improve skin elasticity. Directions on the label call for applying the cream over the body, with emphasis on the abdomen, each morning and evening. This is a topical cosmetic use rather than a treatment for an underlying medical condition.
