mine did the same thing…my tattoo was so bright and shiney when i got it then 4-5 days later it began peeling…and i got scared because the color under it was not as shiney and bright. but don’t worry especially since your ink isn’t finished. its all normal.
for the shading part…put your ointments on until your told not to and then lotion and let it heal on its own…keep it aired out…i got mine on my shoulder and wore tank tops for a couple weeks …mine doesn’t look as light and weird as it first did…so don’t worry. good luck!
