Pigmented scars on the legs can be improved with a combination of Melarase AM and Melarase PM creams. I would begin treatment with Melarase cream twice daily to reduce discoloration.

Melarase creams for leg scars that are discolored
It is difficult to see in the pictures if it is a bug bite or something else happening in the dermis of the skin. I would recommend seeing a dermatologist and getting a biopsy with sending skin specimen to a dermatopathologist give you a read. This will give you a better idea and can help guide treatment options.
