At the age of 23, the chances of height increase are very less and you are having a standard height as per our geographical location. The most of the Indians have this height. So stop worrying and don't get lured by fake claims for height increase by medication. Purchase shoe with heal to increase one to two inch height in appearance. In market shoes with inner heal are also available. But I suggest you to improve your personality with confidence and don't consider height as a matter of success. You are the best person and prove it by expressing yourself with confidence. Good luck.
