If after two weeks, you notice the pigment is completely gone, then this is normal. It is entirely possible that your specialist did not go deep enough with the cuts. The artist needs to cut into the dermal-epidermal junction for the pigment to stay deep enough and last. If the wound only reaches the superficial epidermal layer, your body ends up pushing the pigment entirely out as it heals. When the pigment is placed deep enough, the skin heals over it, rather than evicting it.
You can usually tell if your specialist has reached a thick enough layer because you will hear a “tearing” sound in the skin. There is usually some pain, but not a lot due to the area being numbed beforehand. If you start to notice the pigment is in the healing scabs, this is an indicator that it is being pushed out and was not placed deep enough. After two weeks, it will be gone entirely. The unfortunate side to this is that you will have to get the procedure done again, preferably by a different artist.
