yeah ive heard of things like this before...
never tried it, some guy said on his comments on the thread that it does help reduce puffyness but not the darkness....
Ive just come down to the fact its in the genes, ive been sweating alot and working out weekly past few weeks and no difference so its just the way I am and have to accept it.
There will always be 100 cures to dark circles but just like hair loss nothing 100% working or confirmed.
