Joshua Solution 14ml is a higher concentration of the smaller 4ml roll on tube of doctors cold sore solution.

Many people ask why it is not the same solution in the roll on tubes? Well, in order for the roll on to work correctly a gelling agent has been added therefore diluting the active ingredients within the solution.

We recommend that you use the 14ml bottle of Joshua Solution in the home and the doctors cold sore solution roll on tube whilst out and about or at work. Obviously the 4ml roll on tube is more convenient and easy to carry around.
