I have a rash on my face, is it a skin infection?

Had a rash appear on my chin two weeks or so go I thought it was deep cystic acne as it was very swollen red and hot with and orange coating over the top. it’s now scabbed and
Healed but I’ve not come out with it on my cheek? they are very sore to touch love
Never suffered from acne so maybe it’s a
Skin infection?
