Itchy face after oil usage

Patient: 3 day ago i got Tea Tree oil and i read that it can reduce pain from pimples so i put it on my face. But i forgot that i have some allergies, plants allergy etc and tea tree oil is from a plant. So i got an allergic reaction the places i put the oil on are red and itchy and i don’t know what to do. I put ice there but it is just relief for a while. Should i be concerned or it will go away in few days? Is there anything that will help me? thanks. (sorry for my english)

Symptoms: itchy, red face
