5 Signs Your Tattoo Ink Has Gone Bad

Not sure if that bottle is still good? These five signs tell you when tattoo or PMU ink has gone bad and should be thrown out.

1. The Ink Has Separated

Some settling is normal and fixes with a shake. But if pigment and liquid stay split after mixing, the formula has broken down and the bottle is done.

2. The Color Has Shifted

A tone that looks duller, darker, or off from when you bought it has likely degraded. Color shift means unstable pigment and unpredictable healed results.

3. You See Clumps or Graininess

Lumps, grit, or a thickened texture are clear spoilage signals. Never push clumpy ink through a cartridge or needle.

4. There Is an Odd Smell

Ink should be near odorless. A sour, chemical, or otherwise strange smell means bacterial growth or chemical breakdown. Discard it.

5. The Date Has Passed

If the bottle is past its manufacture or open date and you cannot confirm storage, do not risk it. Fresh stock is cheaper than a lost client or a complication.

What to Do Instead

Retire questionable bottles and keep a steady supply of fresh, dated, sealed ink. Store it well (see our storage guide) so you waste less and protect every result.
