I have dark patches occuring on my face.  it started with slight marks on the cheeks which increased in size and now the mark also came on forehead.  doctor diagnosed it as melasma and prescribed Melalite-XL cream for 6 weeks and later reducing it with melalong.  There has been no improvement in the marks though.  I tried using Eumosome - m on the marks and i saw visible difference with the marks getting lighter.  I feel its not melasma.  Can you advise your diagnosis please.  Thanks a ton.

Dear Pam, Welcome to Chat Doctor. After reading your problem the most common possibility appears to be Plasma only. I think you are a young female of age between 20-30. Now there could be second possibility of Post Inflammatory Hyperpigmentation(appearing after any skin problem). But as per your question it does not appear that any rash or something occurred on your face. Now for Plasma, it is a condition of hyperpigmentation occurring mainly over cheeks and sometimes on forehead too in superficial or deeper pigmentation.  It is considered to be a hormonal problem due to female hormones. Though it can occur frequently in men too. Now that you were prescribed with Melalite-XL cream for 6 weeks and later with Mel along. Both of these contains HY Chat Doctor.  The deeper pigmentation does not respond to this, which is the reason of no improvement in the marks. Response to Eurozone is variable thing, as is a type of topical STEROID- and every skin condition responds well in the beginning, but is a double-edged sword-giving benefit in beginning but later making dependency and innumerable side effects. So Kindly stop using that if you are not using for long term or slowly taper it off. You can ask your doctor for best and safest possible therapy for you which can be used for a longer period of time. Hope to HAE justified with your problem and query, With best of wishes for healthy glowing skin,
