Hi, had this tattoo for just over 3 weeks now. The scabs have been and gone, and I've noticed there are some white ish bits in some places. I'm aware of the 'milky' stage after scabbing, but the two white bits toward the bottom are lower than the rest of the tattoo like it's missing skin. These were also the last bits to scab, just wondering if this is normal or will need touching up?
