PIH treatment with Melarase creams
I would recommend a combination of Plato's Scar Serum, Melarase PM, and Melapads to help with the PIH>
Treatment of postinflammatory hyperpigmentation
Thanks for your question. Retin A can certainly be helpful for this condition, but it would work better if combined with other agents which improve the distribution of pigment and melanocyte function. In the ZO SKin Health line, Melamix (containing 4% Hydroquinone) is combined with Retin A at night and Melamin (also 4% Hydroquinone) is used in the daytime. 4% Hydroquinone products should be used for a maximum of 18 weeks consecutive, at which point you should switch to non hydroquinone brighteners such as ZO Skin Health Brightenex (facial lightening) and Brightamax (non facial/body skin lightening). Medical grade vitamin C can also be helpful- concentration should be 10% or more.
Procedures such as microneedling with platelet rich plasma "Vampire facial" can help also.
Intense pulse light ("photofacials") can coagulate existing pigment to get it to shed faster, but given your tendency towards PIH, you should be on a skin conditioning program (hydroquinone) for a good 6 to 12 weeks before any energy based intervention, and even before microneedling, to ensure that the healing phase after your procedure does not lead to unwanted pigment response.
