"It seems to me that the first licence to P&G relates to a non-powered wand to be used in conjunction with the Olay Regenerist product range. Would that mean there won't be repeat sales if the wand has a relatively long life span??"

A very good point and one which I had not previously considered. From a marketing point of view my guess would be the applicator is supplied with every jar of the product regardless of if the wand has an infinite lifespan.
