Can I Regain My Original Skin Tone? - #49581

I'm 23 year female now, recently I got know that I was born very much fair but at that time I was suffering with Zondice, I was in Under Weight around 2 kgs, also I drank some fluids in womb, inorder to treat these issues I was kept under ventilation for 23 days itseems and some kind of medications, for that I havebeen drastically changed my skin tone from complete fair to complete dark, also after coming home, I was supposed to slept on cot under the dhuni to cope up with the cold climate aa I was born in winter season regards this,until today I didn't get the color when I was born. My question is, do I really get the tone of the color at the time of our birth, if so what are the ayurvedic practices for it to gain, also I known that I wasn't born reddish, it's purely fair ones, then I really miss that skin tone, I want to regain my birth color, will that be possible, I request you to tell me the solution for this concern. Thank you.
