The irritation of the skin triggered by a reaction to Urushiol (found in the resin of poison oak) usually appears within 48 hours after contact, and it can be pretty quickly – there are people who have developed the symptoms of the rash in just 30 minutes.
On the other side of the spectrum, we have people who have experienced the rash 14 days after the exposure, and usually in those cases where the rash takes more time to appear, the allergic reaction is more severe. The symptoms of a poison oak allergic reaction include redness, blistering, swelling and sever itching.
How long does it take to heal poison oak?
It depends on the severity of the case. In mild cases of poison oak, it will take a week or 10 days to fully heal the skin. In severe cases, it could take more than three weeks to get rid of the rash. If you have pale skin, you are more prone at developing the symptoms of a poison oak rash.
