How soon do symptoms of a skin allergy appear?

ANSWER

An allergic skin reaction can start right after you touch something. You can also suddenly become allergic to something that has never bothered you before. So, don’t rule out something you’ve used for years. But your symptoms may not show up for a day or two after you’re exposed.
