You have been using MELALITE XL cream since long.
This cream contains hydroquinone + Tretinoin
It is a triple combination commonly used by dermatologists for treating hyperpigmentation
, but one has to use this cream with caution.
It has to be applied only at night.
Moreover, it should not be rubbed over the skin and very small amount has to be applied.
At a stretch, this cream is not to be used for more than 2-3 months.
Long term use of these agents on the face can lead to various problems like skin thinning,photosensitivity
, hair growth, redness, pigmentation etc.
So firstly, I would advise you to stop using this cream .
You can start using a lightening agent like kojic acid with vitamin C twice a day. Along with it, you should continuously use a sunscreen( spf>26) over your face before going out in the sun.
Also take oral vitamin C supplementation continously for a month or so.
If inspite of all these measures, you feel that the pigmentation continues to persisit, then I would advise you to see a dermatologist who might be able to help you with other techniques like chemical peels
, dermabrasion , lasers etc .
Hope it helps
