I already got my feet diagnosed by a dermatologist and he said it is hyperpigmentation. He cannot explain why I have it though. He says lasers could make it worse, but I am willing to chance it anyway because they already look horrible. He said if i wanted to find out if the hyperpigmentation is linked to something harmful, he could biopsy it, but still he wouldn't have a proper solution for the hyperpigmentation. So can these lasers help me in this case? Has any doc seen a case like this?
