Peptides are short chains of amino acids, the building blocks of proteins such as collagen. In skincare, different peptides are studied for their ability to support the biological pathways linked to skin smoothness, resilience and visible signs of ageing.
Acetyl Hexapeptide-8 has been widely studied in relation to the appearance of expression lines and the signalling pathways associated with repeated facial movement.
Palmitoyl Tetrapeptide-7 is researched for its role in skin communication and pathways associated with inflammation and the extracellular matrix, making it an interesting peptide for supporting overall skin condition.
Palmitoyl Pentapeptide-4 is a well-known signal peptide studied for its relationship with collagen and other structural components of the skin, with research exploring its potential to support smoother, firmer-looking skin.
Together, these peptides represent a modern approach to skincare focused on supporting the signals and processes associated with smoother, more resilient-looking skin, rather than making claims about replacing collagen or reversing skin ageing.
