For lack of a better term, I call this the healing zipper. When you push the needle in and make the tunnel or pocket for the implant, then deposit the implant into this space, the body kind of heals in reverse and will push the implant back toward the incision. Sometimes it’s just a millimeter but sometimes it’s significantly more. Important thing is that this is normal and it will all settle out… Unless you develop a migration problem, which is different.
