However, there are well known causes like pregnancy, oral contraceptive pills, certain painkillers. You have been on the right treatment for plasma, results can take some time, usually 2-3 months and even longer. It is important to protect from sun during the treatment for plasma, otherwise you might see the desired results. I hope you are using a sunscreen, though you didnt mention good sunscreen should have broad spectrum UV A coverage in addition to UV B coverage, in order to be able to prevent tanning, and it needs to be applied in sufficient quantity and every 2-3 hourly. I dont see sunscreen in your treatment. A sunscreen with minimum 30 SPF would be adequate. It should mention both UV B and UV A coverage. Therefore, it is important to select the right sunscreen for desired effects It should be applied in the following quantity:--3ml for face and necka little more than 12 teaspoon--3ml for each arma little more than 12 teaspoon. A sunscreen should be applied every 2-3 hours. You can opt for a few Chemical peeling sessions from a dermatologist. Peels are very useful for Pigmentation over face. They can be used either alone OR in combination with skin lightening creams. Regards
