A four-ingredient oil versus a multi-ingredient cream. Here is what is in each and how they feel.
Penetrex is a cream and roll-on gel with a long ingredient list, including arnica, vitamin B6, MSM, glucosamine and boswellia, plus camphor and peppermint oil. Outback Original Oil has four ingredients, no camphor or menthol, and soaks in as a light oil. If you want the shortest label and no scent of camphor, Outback is the simpler choice.
