Hello and thanks for the query.
You can put some neosporin along the suture line. This would be safe and not XXXXXXX nor will it cause a breakdown of the healing tissue.
I recommend you apply a thin film three times daily which should aid the healing process. Within 7 to 10 days I would expect the irritation to be almost completely resolved.
Thanks again for submitting your query. I hope you have found this response to be timely and adequate. Should you have additional concerns regarding this issue I would be happy to address them.
Regards,
Dr. Galamaga
