Best medical-grade adhesives?

I'm looking for recommendations on skin-safe adhesives—specifically for body use. The main requirement is that it can't be harsh or trigger an allergic reaction, since I need to secure a hearing aid in place.

What is this type of skin-applicable adhesive actually called? Is there a specific term like "cosmetic adhesive" or something else?

I haven't really dealt with this stuff personally, so I can't exactly give you a firsthand testimonial or anything... but if you want to make your life a little easier while you're hunting around, check out this link. Might be right up your alley:
