Dark scars and Melarase PM
Ideally, I would start with Melarase PM cream mixed with Plato's Scar Serum to help reduce pigmentation.
Post Inflammatory Hyperpigmentation - treatment options
PIH of a recent onset (days to weeks) responds to topical agents like azelaic acid, short contact, short duraation hydroquinone, kojic acid and so on. For spots that persist, we use a picosecond laser. Do make sure to use a good sunscreen, to maximise treatment outcomes.
