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
