How To Get Glowing Skin?

Hi..

Im 22 years old.

I have brown skin, but it was shiny and healthy till few months back.

I got some skin infection because of some unknown reason. I consulted a skin specialist and he prescribed a gel(Klear up). After using that cream, that infection went off along with the glow of my skin:-(

I need my skin glow back. Kindly advice.
