Science
Mechanism of Action
Polyamide-1 functions by depositing a coherent, stable film onto the surface of the skin, hair, or nails upon application. This continuous film acts as a physical barrier, which can assist in moisture retention, enhance product longevity, and improve the textural feel of the applied formulation.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed a broader class of nylon polymers, generally deeming them safe and unlikely to penetrate the skin. However, this specific assessment does not directly apply to Polyamide-1. There is no specific SCCS opinion directly available for Polyamide-1. While related polyamide resins are listed in the FDA's inventory for food contact substances, this pertains to packaging rather than direct cosmetic safety. The Environmental Working Group (EWG) rates Polyamide-1 with 'LOW' concerns for cancer, allergies & immunotoxicity, and developmental & reproductive toxicity, though it highlights 'Low Availability' of scientific data.

Verdict
While Polyamide-1 is recognized for its film-forming properties in various cosmetic applications, there is currently insufficient specific safety and efficacy data to provide a conclusive assessment for precision skincare.
