Dry lips while playing harmonica

I sometimes have problems with my lips becoming very dry while playing. Of course I try to find a slot within the song where I have a second to make them wed again wih my tongue, but this is not always working out sufficiently ....

Yet my question is if there is any kind of product or liquid with which I could treat my lips beforehand so that they less quickly dry out .... Of course such product should not be causing the harmonica to become sticky....

Wonder if other people also experience this problem, and how they cope with / solve this situation

Many thanks in advance for your feedback
