Hi, My recommendations for a cleanser post microneedling would be more of a gentle cream type cleanser that is not drying to the skin. Most antibacterial washes are quite harsh and drying. If you are concerned about infection due to the microneedling procedure, have it done with a reputable medical professional and taking care to avoid touching the face post proceedure are two things you can and should do. We naturally have all sorts of natural bacteria on our face that is protective and antibacterial soaps are not discriminating in terms of what they kill, so overall you are better off not using post proceedure, or at all for that reason. I hope that helps, Dr. Heskett
