Inside-out beauty

A sporting injury almost 20 years ago led James to discover the incredible benefits of collagen from the inside-out.


James’s skin was often tested as a pentathlete, suffering from acne throughout his time competing. James wasn’t anticipating the results collagen would have on his skin, and to this day, collagen is part of his everyday routine.

James’s passion for collagen and his transformation soon led to Proto-col’s birth in 2003. He still has the same goal, to make collagen-infused health and beauty products accessible to men and women everywhere.
