What is a bovine collagen ?
So called “bovine collagen” is a fibre of pentanary insoluble collagen cut from the nape of young cattle. This protein has such a large molecular mass, that it really has no chance to penetrate the barrier of the stratum corneum other than by invasive sclerotherapy for which fragments of these fibres are used. It is a biologically inactive emulsifier because it is only a pulp of fragments cut from peptide chains and used as filler in diet supplements or as a component in cosmetics.
