The ointment is in a petrolatum base. While not technically comedogenic, it is extremely thick. Because of this it will form a layer on your skin rather than absorb into it. So what that means is it creates an enclosed moist environment in your skin with no oxygen supply....the perfect breeding ground for acne.
Also, the actual label will read Neosporin+Pain Relief. I don't think the Neo cream is available without the pain relief ingredient. I've talked to someone who has used both the Neo+PR
and a generic brand without the PR
ingredient and there is apparently no difference in effectiveness.
I purchased the cream at Wal-mart but it should be available at any pharmacy.
