Bruising left from laser treatment. Should I be worried? (photo)

hello, had a few spider veins on my face and chest: removed them by laser (not sure which one thou). This is what i am left with . I did read that some lasers can cause bruising (even if this is not my first time and it never happened before), but i am worried whether the skin has been blistered. Also not sure what cream shall i use to make all this disappear faster (antibiotic cream? plain hydrating cream? ). Can this get worst since i only did it this morning?
