Hi Tommy,
You said it yourself, “around the treated area”. So that means what you are experiencing is absolutely normal. Your hairs will not come back thicker (if they come back at all).
Now, if you told me you had pits or other types of scarring, I would then think you should be stressed. However, that does not appear to be the case.
Relax and be thankful that you’ll be hair free soon!
Cheers,
