The present invention relates to the Synthesis of Triterpenoid peptides and mechanism of action for Anti ageing and skin care. The present invention is directed towards anti-aging skin care compositions comprising peptides which are made by linking herbal actives to a pentapeptide for enhanced anti ageing activity by regenerating the dermal matrix. In detail, the present invention relates to the synthesis of Triterpenoid peptides, providing an enhanced and synergistic activity for reducing the consequences of ageing such as appearance of fine expression lines and wrinkles on the skin by cosmetic modes of application. The Triterpenoid peptides of the present invention with its novel dual action mode can be used for skin ageing & collagen insufficiency. Its Triterpenoid group acts by preventing oxidation and excess activity of serine proteases like elastase and collagenase that result in wrinkling of skin. With added peptides which boost the collagen and other matrix protein, Triterpenoid peptides provide a complete protection against pre mature ageing and functions as a best anti ageing ingredient.
