hi..i have like a half spherical brown tiny ball on my face..i used to put "molutrex" on it.. i used this medicine for 10 days..this medicine burns it.....it disappeard, but the skin color where it was ,is different from my skin (maybe from the burn)..but i have no pain sinve like 7 days after i stoped using "molutrex"...the idea is just that this tiny ball disappeared but i had a skin color dismatch..so my question is: does the skin color rematch during days? ...my age is 23 years old.im a 81 kg man.. 187 cm height...i dont't have any medical problems
