TAN?! HELP 😯

I was born 10 weeks early so my skin has always been pale. However with my heritage I should have come out much much darker! You can see my veins circulating through my entire hand up my forearm. And on my feet you could make out nearly ever vein. As if I am paper with the light shining in.

Anyone know any semi permanent ways to darken my skin? Without a sunbed or tanning. (I don't tan well I just burn)
