Is dermal melasma on Asian Indian skin treatable?

Yes. You are an excellent candidate for Permea by Solta. I suggest using ZO (Dr. Zein Obagi's line) Melamin AM-with Sunscreen, and Melamix-mixed with Retin-A 0.05%PM for 4-6 weeks prior to tx. For optimal results, you'll need to do laser 4 times minimum with 4 weeks in between. Be well#laserandmelasma   #hydroquinone   #therapy

Thank you for your question.  Skin discoloration is a very prevalent problem in women over the age of twenty.  It is also increasingly common in men with increased sun exposure.  
Risk factors include thyroid disease, sun exposure, hormones, pregnancy, family history, PIH, and birth control. Melarase AM and Melarase PM have been extremely effective in reducing pigmentation associated with skin discoloration and hyperstimulation of melanocytes. 
In my practice, patients with hyperpigmentation benefit from twice daily application of the creams. Melarase AM in the morning, followed by Melarase PM in the evening. Melarase AM contains four active sunblocks, so sunscreen is not needed unless your sun exposure is very high or you had a recent procedure/laser. SPF of 30. Melarase PM contains active skin lighteners to even out skin pigmentation. If you are concerned about the development of pigmentation, contact our office to discuss details and to obtain a regimen for Melarase.

You can get improvement but there is no cure. It can always flare and needs a short and long term treatment plan.  Best, Dr. Emer.
