Tripeptide-56

Tripeptide-56 is a signalling peptide derived from matrikines—naturally occurring fragments of extracellular matrix proteins. It functions as a skin conditioning agent that communicates with fibroblasts, the cells responsible for producing structural proteins in the skin.In formulations, it is often paired with other actives to enhance stability and efficacy. The ingredient works at a cellular level rather than providing surface-level hydration or occlusion.

Tripeptide-56 acts as a matrikine mimic, mimicking natural signals that the skin produces to maintain and repair its structural proteins. It communicates with fibroblasts via integrin pathways, triggering them to upregulate genes involved in collagen and fibronectin synthesis.This mechanism differs from surface-level hydrators; instead, it works to reinforce the skin's underlying architecture from within the dermis.

Tripeptide-56 is typically found in serums, moisturisers, and targeted treatments. It works best as part of a consistent routine and is often paired with complementary actives such as antioxidants or other peptides. Allow time for cumulative effects—improvements in skin firmness and structure may take several weeks of regular use.

Peptides are generally well-tolerated and rarely trigger irritation. Suitable for most skin types, including sensitive skin. No known contraindications, though patch testing is advisable if you have very reactive skin.
