Hairspray bad for skin?

I use a lot of hairspray for my up-do hairstyle and consequently I usually get a lot of over spray all over my ears. I never really thought much of it, until one of my friends pointed out and asked why my ears are always glistening and supershiny. Is alcohol based hairspray bad for the skin of my outer ears? I never had any skin irritation (or should I say EAR-itation) on the skin of my ears, but Im thinking anything alcohol based should probably stay off the skin as much as possible?
