I think I'm going through exactly the same thing with my son Will (15 months). He had his 3rd laser treatment over 10 weeks ago on his facial pws birthmark and it is still redder than what it was prior to this. It was quite an aggressive treatment with some scabbing. We saw great results with the first two, however, I'm feeling rather anxious at this point. I was wondering too whether laser treatment can make a pws birthmark redder. Like many of you on this thread I hope that it's just part of the healing process.
