Whats the difference between a pimple, a wart, and an ingrown hair?

no this is not a riddle...haha|||A pimple is caused by a clogged pore that causes an infection. An ingrown hair is similar to a pimple but the cause is that the very end of the hair failed to come out of the skin. This hair trapped under the skin continues to grow causing infection. A wart is caused by a virus. Unless the wart is on your hands you should show it to a doctor. There are different kinds that need different treatment.
