Palmitoyl Tripeptide-5 Amidopropyl Ascorbyl Phosphate Hcl

Palmitoyl Tripeptide-5 Amidopropyl Ascorbyl Phosphate HCl is a hybrid ingredient that combines a stabilised form of vitamin C with a short peptide chain. Vitamin C (in this esterified form) is a well-established antioxidant, whilst the tripeptide component is a small protein fragment designed to support skin conditioning. This combination is formulated to enhance skin texture and resilience.The ingredient functions primarily as a skin conditioner, helping to maintain the skin's barrier function and overall appearance. It is typically used in serums and treatment products at modest concentra…

The vitamin C portion works as an antioxidant, neutralising free radicals that can damage skin cells and contribute to visible ageing. The esterified (stabilised) form makes it more shelf-stable and less irritating than raw ascorbic acid, whilst still offering antioxidant benefits.The tripeptide acts as a signalling molecule, potentially supporting the skin's natural conditioning processes and barrier maintenance. Together, these components work to protect and condition the skin rather than driving dramatic structural changes.

Use as directed by the product instructions, typically once or twice daily in a serum or treatment. Apply to clean skin before moisturiser. This ingredient works well in layered routines and does not typically require special pairing restrictions, though it may be combined with other antioxidants for enhanced protection. Allow the product to absorb fully before applying subsequent layers.

Generally well-tolerated by most skin types. The stabilised vitamin C form is typically gentler than pure ascorbic acid. Those with very sensitive skin or known sensitivities to peptides should patch-test first.
