Hi my son had three laser sessions on his bottom lip.
After the first the H stared in about 3 weeks growing again. The sign that it started growing was that it was swelling and red spots started appearing
After the third laser (now 11 months have passed) the sweeling gradually diminishes, there is no great scarring and has 6 or 7 red spots that are steady, not gowing and the doctor said that they will go away in time.
I believe that laser was the best decision because surgery might remove part of the lip in order to clean it from the H.
You just have to be patient and o not get disppointed because the H might be appearing again and again.
Have faith you wii eventually beat it!
