Asked for female, 13 years old from Hyderabad
As you grow up and start doing out more the exposure to sunlight increase. And that causes tanning. Being indian we have dark complexion in our genes.
So it is not possible that you become fair like before except if you stop going out completely which is not practical.
Yes with proper skin care and some good products. The skin color can be improved greatly.
Like when you go out cover the skin as much as possible.
Take more fruits and juices freshly prepared and not packaged. For high amount of antioxidants.
You can also use glutathione products. Preferably injections if want faster results.
For more information you can consult me at Lybrate.
