Syn-Coll, otherwise known as Palmitoyl Tripeptide-5 or Tripeptide-5, is a synthetic peptide that was developed to enhance the production of type I collagen. It appears to repair damages caused by photo-aging, and Syn-Coll has also been suggested to support the regeneration of skin protein production, such as elastin or collagen. Syn-Coll (Palmitoyl Tripeptide-5) is the synthetic equivalent of Thrombospondin 1 (TSP-1). TSP-1 is an extracellular matrix protein and is found in the skin near collagen and elastin. Syn-Coll appears to mimic the functions of TSP-1, possibly aiding in the prevention of collagen degeneration via stimulating the release of TGF-𝛃 induced by TSP-1.[1] TGF-β is an essential growth factor potentially significant in preserving skin integrity and facilitating the development of skin structures, mainly through the promotion of collagen synthesis. Additionally, Syn-Coll, a synthetic peptide, has been the subject of extensive research in animal models and laboratory experiments. The findings tentatively indicate that Syn-Coll might enhance collagen production and potentially inhibit its degradation. The inhibition of collagen breakdown by Syn-Coll is possibly due to its ability to suppress the activity of matrix metalloproteinases (MMPs), including MMP1 and MMP3, which are enzymes studied for their role in the degradation of collagen in the skin. The peptide is palmitoylated, to potentially extend its bioavailability in experiments involving different skin tissue models.
