Syn-Coll and Collagen Production Stimulation

by | Sep 21, 2022 | Research

Syn-coll peptide or Palmitoyl Tripeptide-5 is a peptide that has been hypothesized to increase the production of Type I and Type III collagen while inhibiting its degradation (1). It is also known as Palmitoyl Tripeptide-5 or Tripeptide-5. Syn-coll peptide appears to induce these functions by activating the transforming growth factor.

Research has suggested that Syn-coll may function similarly to Thrombospondin-1 by stimulating the breakdown of collagen caused by transforming growth factors. A naturally occurring peptide called TSP-1 is considered to promote TGF- activity. Syn-coll peptide is suggested to host the same properties as TSP-1 in increasing Type I and III collagen levels in dermal (skin) fibroblasts. According to experimental results, Syn-coll may raise type I and III collagen levels by 2-3 folds above normal levels(2). Varga et al. further suggest, ‘Our results indicate that TGF beta causes a marked enhancement of the production of types I and III collagens and fibronectin by cultured normal … dermal fibroblasts. The rate of collagen production by fibroblasts exposed to TGF beta was 2-3-fold greater than that of control cells. These effects were associated with a 2-3-fold increase in the steady-state amounts of types I and III collagen mRNAs and a 5-8-fold increase in the amounts of fibronectin mRNAs as determined by dot-blot hybridization with specific cloned cDNA probes. In addition, the increased production of collagen and fibronectin and the increased amounts of their corresponding mRNAs remained elevated for at least 72 h after the removal of TGF beta. These findings suggest that TGF beta may play a major role in the normal regulation of extracellular matrix production in vivo and may contribute to the development of pathological states of fibrosis’ (2) TSP-1 is a protein found in the extracellular matrix (ECM), and it is considered to be found alongside collagen and elastin.

Research regarding Palmitoyl Tripeptide-5, like TSP-1, suggests that this peptide may improve wound healing (3). It appears to participate in the development of skin structures. The Syn-coll peptide may inhibits matrix metalloproteinase I and III activity (MMP1 and MMP3). Enzymes that degrade collagen are known as matrix metalloproteinases. These enzymes may be beneficial because they recycle collagen, but appear uncontrollably increased to abnormal levels in conditions such as inflammation. As a result, premature skin damage, lines, and creasing along the skin structure may appear (3).

Syn-coll may potentially support the elimination of toxins and reduce the development and depth of wrinkles on the skin surface. Syn-coll appears to interact with the skin, keeping toxins at bay. This procedure may shield from free radicals.

By possibly inhibiting MMP1 and MMP3 activity, Syn-coll peptide may potentially help to prevent collagen breakdown. These hypotheses suggest that Syn-coll peptide may promote the formation of Type I and Type III collagen while inhibiting collagen breakdown by the enzymes, as mentioned earlier.

Syn-coll, a synthetic peptide component, has been hypothesized to have two primary effects. It appears to increase collagen production by replicating the activation of latent transforming growth factor beta, TGF (Tissue Growth Factor), considered a critical component in collagen synthesis. It appears to protect collagen from breakdown by inhibiting matrix metalloproteinases (MMP). Both activities may work together to keep the skin’s structural integrity intact. Compared to a placebo, Syn-coll peptide may be up to 3.5 times more impactful in wrinkle depth reduction. According to the researchers, Palmitoyl Tripeptide-5 may be 60% more effective than Palmitoyl Pentapeptide (5).
