No one can give a definite answer if anything will work! We certainly hope that the applied products, whatever they may be, will help. I’m telling you what I would advise and at the top of the list would be to let Mother Nature heal this and that will take time. YOU are the one that has to decide which way to go given the options presented. At this point, and hearing how you are demanding that something be done quickly, I would just say to follow what your dermatologist suggests. His or her years of education and practice trump mine and they can see you.
Your English is great, by the way, and I would say something again in plain English or whatever the language you speak, to this person that performed poor electrolysis on you something to the effect about the costs this has incurred to you. At the very least, since this is costing you, present your receipts for medicants and derm visits to her and ask her to pony up (reimburse you).
I’m still thinking that this will heal. The skin can re-structure itself pretty well if you give it TIME and not do anything to it that hampers the normal healing process.
Follow the advice of your dermatologist and see where it takes you.
