Hello!Thanks for your query! Melacare Forte cream has hydroquinone( skin-bleaching agent),steroid and a retinoid.This is used to lighten areas of darkened skin such as freckles, chloasma (also known as melasma), age spots, and acne scars.It should not be used very continuously as u have.Prolonged use of Hydroquinone has been associated with the development of exogenous ochronosis (a persistent blue-black pigmentation).The steroid which is contained in the product also leads to a lot of steroid related side effects like thinning and atrophy of skin.Used over a period of time they suppress the melanogenesis process,and once you stop it, the come back! Instead of this , if you can prevent the day to day darkening of your skin, by using a broad spectrum sunscreen every 4 hourly, you will see a significant lightening of the color. U can do a few sittings of Chemical peels from a dermatologist as these help more in exfoliation and lightening.They are also safe when done properly. Hope this helps..Take care
