It’s winter here, and so often my lips end up pretty chapped or cracked. This is pretty irritating, especially since I’m a brass player. I often use products like Lip Medex or DCT. You know, lip goo. Comes in a wee little jar and you smear it on your dried out lips to protect them from wind, sun, whatever. Last year, some other brass players I know told me I should specifically not use Lip Medex because it’s got camphor (or however it’s spelled) in it. They told me it would somehow damage my lip tissue or it was bad for the surrounding muscles or some such thing. Is there any truth to these ideas?
