The one-shade rule
New ink goes under existing ink, not over it. Skin is translucent and everything you add sits in the same layer as what is already there, so the result is the sum of both. That means a cover-up can only ever be darker than the piece underneath, and in practice it needs to be about one full shade darker to read cleanly.
Which is why a faded grey script covers easily and a solid black tribal piece from 2003 does not. It is also why the honest first step is often laser: three to five sessions to lighten, then a cover with real options instead of a black shape that is technically a cover-up and aesthetically a compromise.
What we will tell you at the consult
One of three things, and we say which in the first ten minutes.
Coverable as it is. The old piece is light or broken enough that a new design can absorb it without dictating the whole composition. Most faded work, most single-pass line work, most old script.
Coverable after laser. Three to five laser sessions, six to eight weeks apart, then we cover. This is a nine-month path and it is the honest answer perhaps a third of the time. We will name a clinic; we do not take a referral fee.
Better as a rework. Sometimes the piece underneath is decent and what it needs is to be extended, re-lined and pulled into something larger rather than hidden. This is the answer people are least expecting and like most.
