I am this color

And my goal is
To achieve this.. I was going to do
Retin A 0.05 and hq 4% for my face
Initially I wanted to do 10%hq on my body.. but I can't find any where in GTA that's sell the hq powder! I was going to do this with a peel as well !
If I use skin light body cream 2% in the morning , and my 4% in the night (which is hard because the tube is so small) along with a peel..
Do you think I'll reach my goal in 3-4 months?
