Tattoo removal: worried about ink oxidizing and that I have tan skin - advice? (photo)

Got a tattoo 6 days ago and I want it gone. I’m of East Asian descent and the part of the tattoo I’m worried about removing has yellow ink as well as yellow mixed with white ink. I’m afraid of the white ink oxidizing and making the whole process useless. If that happens is it fixable? Also considering tattoo excision just to avoid the fear of oxidization and to guarantee an entire removal but I don’t know if my tattoo is even viable for that considering it’s about 4.3in x 3.5in
