I have dark spots on the face & neck also on my Hand. One of Dermatologist suggest me Tri o Bloc on Night, Eumosone in Morning, Whitesol in Night (2 days in a week) also He suggest me to take B Complex tablet daily for 40 days. I take this treatment by 2 months but no much effect on dark spots.

Also I check Harmone test and Vitamin D 12, but it's normal.
Pl. suggest me
