Hello and welcome to healthcaremagic The cream (melacare) that you have been using is a drug combination of a potent topical steroid (mometasone), tretinoin and hydroquinone. It is a prescription product. Dermatologist s commonly prescribe them for facial hyperpigmentation/ melasma. It won t cause skin cancer, however, it is not meant for regular use and should never be used without a dermatologist s advice and in any case not for more than 2-3 months since the steroid content of this cream can cause various side effects like acne, photosensitivity, skin thinning and telangiectasia and facial hair growth (hirsutism) which is specially troublesome in females. You should definitely stop using it any further. Rather I would suggest you to use a broad spectrum sunscreen, throughout the day and a skin lightening cream containing one or more of the following agents like kojic acid, glycolic acid, arbutin, liquorice, magmebsium ascorbyl phosphate etc at night. These ingredients are safer even if used over a longer duration of time. OR else you could also opt for a few peeling sessions from a dermatologist to enhance your skin. Glycolic acid peeling would produce the desired results of skin lightening, even tone and reduced pore size. Regards
