I m 28years female suffering from dark circles as I m working on computer my eyes are weak so I m using contact lens for my eyes vision. 1 Dr. suggested me kojivit gel and carofit plus tab for cure. I just want to ask that for how many months should I take medicine Dr. and can I exchange carofit plus to another tab because I couldn't found this tab in chemist shop. Are dark circles really diminish by using all this because its not heredity for me when I m in fever its get so dark sometimes its get low. What is the true care to remove these ugly circles pls suggest me. Thank you.
