White spots on my back

Hi,
My name is Milos and I live in Serbia.
I was born with a small white spot on my back.
But last year few more white spots came on my back and chest.
They grew a little bit and they are now 2 cm wide.We thought it is from the sun but then we went to the doctor and he said it might be from the stress or I have less pigments on my skin.
He gave me a medicine ''Lotion Melagenina Plus''.
I was using it but nothing happened.
Also doctor said it might go off after Puberty.
Do you have some suggestions to take off that white spots?

May be spots of vitiligo.External application of steroid like betnovate help in getting back the pigment.A photo would have been better to give a  diagnosis.
