M.Sc International Health Science
Skills you need are some sort of passion so you can put in the hours of forced memorization. Attention to detail, and at early stage understanding the science behind everything.
Thus, for you to become a biochemist, you have to love staying long hours at a lab looking through a microscope investing multiple results from your research while also looking into how could that be best applied on things that might be useful to people outside the lab.
So you need to learn biology, how living things work on microscopic levels, and also chemistry to see how the elements from the periodic table work, only then proceed to combine both.
Honestly I don’t know how wide the need for biochemists is, but if you’re willing to put in the time, the work and the passion together I believe it’s an interesting field to explore.
