Hi, Kojivit plus cream can be used for various conditions of skin, which require skin lightening like acne, sun burns, pre-mature aging, vitamin E deficiency, post inflammatory pigmentation, etc. It contains kojic dipalmitate, arbutin, mulberry extract, grape seed extract, allantoin, glycolic acid, vitamin E etc. All these constituents act together to block melanin pigments and act in skin lightening effect. As most of the skin lightening products contain simple kojic acid, where as Kojivit plus cream contains kojic acid palmitate and due to this constituent, Kojivit plus cream is more effective than simple kojic acid. This is the reason that this cream gives fast and more effective results from the very first day. Hence, due to its melanin blocking property, you can safely use it for dark circles and patches also. Though, it is almost a safe drug, still, in rare cases local reactions like redness, skin peeling or irritation etc. may be there. If these side effects occur, the drug should be discontinued and opinion of the dermatologist should be taken for further management. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Satnarain Bansal, General & Family Physician
