Hi there Arun.
Dermatology is sadly a very visual field
& as such, one would prefer a clear digital image of the lesion & you may upload it on this HCM website using the upload data icon to the right of your screen.
You may alternatively try to use a Kojic acid
based cream in the evenings & a sunscreen in the mornings for best reults providing you are not allergic to any of the creams components.
Remember to use the sunscreen from dawn to dusk & reapply when sweating or bathing or washing & to be applied each 3-4 hrs..else the pigment lightening cream will cease to be effective.
Good luck & here's to a clear skin soon!
