A pair of fine-tipped tweezers will remove things lodged under your skin and keep you pretty -- quite a multitasker.
More importantly, though, keeping tweezers in your at-home treatment kit allows you to remove foreign objects from your skin -- namely, splinters and ticks.
Most splinters have one end sticking out from your skin. Grab that end with your tweezers and pull it out slowly to be sure it doesn't leave any pieces behind.
Tick removal is a little more difficult. Take hold of the tick's head with your tweezers and pull away from your skin. Be slow and gentle to avoid crushing the tick. Ignore the myths about using nail polish, petroleum jelly or hot matches to get ticks out -- you need tweezers for this task.
