Hello, External applications are no great help in cases of such pigmentation. A course of antoxidants either in form of nutritional suppliments or diet rich in b-carotene would be of help.Indeed it is a question of time before this disappears.
For such type of hyperpigmentation, you can go in for laser treatment, Chemical peeling or microdermabrasion. Avoid picking, harsh scrubbing, and abrasive treatments unless prescribed by a dermatologist during this period.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Hi there- I was wondering how your condition is now? Did the hyper pigmentation finally fade? I have the same thing on my legs from the knees down- I had a pedicure where limes were rubbed all on my legs below the knees, then went outside to the park with my kids. It has been one month, but the color just keeps getting darker and darker! Have been to three doctors. Would love your input and if you have any tips. Thanks- and I hope you are doing better.
