How gotu kola can boost skin firming and help reduce cellulite

  • Asiaticoside is one of the four main chemicals responsible for the tissue repair activity of the Indian herb gotu kola (centella asiatica)
  • Asiaticoside is already known to boost the production of collagen type I (the skin firming protein) in collagen cells, and in this study it was found that asiaticoside exerts this effect without causing fibrosis.
  • This is very useful in cellulite reduction, strecth mark healing and wound healing, where we need to boost collagen levels but without causing fibrosis
  • So in practice, gotu kola extracts rich in asiaticoside can aid in wound healing, stretch mark reduction and cellulite reduction / prevention, as active ingredients in creams or even taken orally
  • Source: Asiaticoside induces human collagen I synthesis through TGF-beta receptor I kinase (TbetaRI kinase)-independent Smad signaling
  • Abstract: Skin aging appears to be principally related to a decrease in the levels of type I collagen, the primary component of the skin dermis. Asiaticoside, a saponin component isolated from Centella asiatica, has been shown to induce type I collagen synthesis in human dermal fibroblast cells. However, the mechanism underlying asiaticoside-induced type I collagen synthesis, especially at a molecular level, remains only partially understood. In this study, we have attempted to characterize the action mechanism of asiaticoside in type I collagen synthesis. Asiaticoside was determined to induce the phosphorylation of both Smad 2 and Smad 3. In addition, we detected the asiaticoside-induced binding of Smad 3 and Smad 4. In a consistent result, the nuclear translocation of the Smad 3 and Smad 4 complex was induced via treatment with asiaticoside, pointing to the involvement of asiaticoside in Smad signaling. In addition, SB431542, an inhibitor of the TGFbeta receptor I (TbetaRI) kinase, which is known to be an activator of the Smad pathway, was not found to inhibit both Smad 2 phosphorylation and Type 1 collagen synthesis induced by asiaticoside. Therefore, our results show that asiaticoside can induce type I collagen synthesis via the activation of the TbetaRI kinase-independent Smad pathway.
