I had this done, four treatments total. My face was really red the first few days, but it was barely noticeable after day 2. It looked like I had a bad sunburn (but not freakishly bad or anything). I don't think you'll scare your kids.
If it wasn't so expensive, I would love to get a few more treatments (I have bad acne scars) but they faded noticeably after each treatment, so I'm happy enough.
