Am I Doing the Right Thing After First Application of Cosmelan?

I had my first application last October 26 which was done at the doctor's clinic.The doctor told me to let the cream stay on my face overnight and I wash it in the morning and afterwards I started applying the home cream which is melasma 2 up to this day which is my 12th day. I am doing the right thing? I understood and aware about the redness, tightness, and flaking. Until when I will be using the cream so I can see the real view of the improvement?
