Hi and welcome to HCM. You have been using melacare since one year now. Melacare cream is a topical cream containing 3 active ingredients which are Hydroquinone, Tretinoin and Mometasone.This cream is commonly used for facial pigmentation but it is very important to use it under strict medical supervision. It is not to be used continuously for more than 2 to 3 three months at a stretch and u have to applly only in night time. Mometasone is a strong steroid and long term use of this may lead to redness, itching, thinning of skin, excessive hair growth,photo sensitivity. Prolonged use of hydroquinone especially during day time can lead to permanent pigmentation over face. First thing STOP USING THIS CREAM RIGHT NOW. For the skin pigmentation that you have developed, you need to start using some milder lightening agents in the form of kojic acid during day time and azelaic acid during night. Both of these have to be applied only over the affected areas. Use a sunscreen lotion with spf more than 26 regularly over your face atleast 20 minutes before going out in the sun. Reapply it every 3-4 hourly if you have prolonged sun exposure. Take oral vitamin c supplementation alongside atleast twice a day. It acts as a systemic lightening agent. Consume lots of fruits, vegetables, eat lots of citrus fruits. Try these for 2-3 months safely, however if you feel that there is not satisfactory improvement, then I would recommend you to see a dermatologist as there are various other treatment options available in the form of chemical peels, dermabrasion and laser treatments which can be done for facial pigmentation. I think i answered your query. All the best Regards Dr Santosh
