Candace, the dark pink is quite normal and can take years to fade. I had one removed on the side of my knee over two years ago and it's lighter, but still pink. You might be developing a keloid scar. I have that in a couple of areas where I had liver surgery. There's some over the counter stuff you can buy to help with that but unless it's in an area that's very noticeable, I'd just let it go. Hubby has some that are HOT pink and stick way up on his shoulders and back.
Sounds like normal healing to me and between the two of us, we've had probably 45 spots removed.
