Cortisone shot for Acne

Patient: I got a Cortisone injection on a big zit yesterday. I’ve had pretty good skin for a year now, and this was the first one in a while (popped up because I poked it). All I’ve been doing in that area since is just cleansing it with an exfoliating cleanser and just letting it heal on its own. Should I be putting anything else on it, like BP (which I use regularly), or just cleanse it and let it heal on its own?
