Nerves (nervs)
Fibers in your body that send signals to your brain when you touch something.

Nickel (ni-kel)
A type of metal in some jewelry. It's a common cause of contact dermatitis, which is an itchy skin condition - so you should try to avoid jewelry that has nickel in it.

Niobium (ny-o-bee-um)
A metal that is used in some earrings. It's good because it usually doesn't cause an allergic reaction.

Nits (nits)
Lice eggs that attach to hair near the scalp or on other parts of the body or to clothing. Lice are tiny bugs that like to live in hair.

Nodules (na-juls)
One of the most serious kinds of pimples. When blocked pores get super irritated, they can form nodules, which feel hard.

Nonacnegenic (non-ak-nee-jen-ik)
This means a skin product doesn't have oil and won't plug your pores, so it usually won't cause pimples.

Noncomedogenic (non-kum-eed-oh-jen-ik)
Like nonacnegenic, this means a skin product doesn't have oil and won't plug your pores, so it usually won't cause pimples.
