SMP can develop a blue or cool-toned appearance, but blue and green discoloration are not inevitable. Light scattering through skin can make dark pigment look bluish; pigment selection, placement depth, dot size, healing, and technique also affect the result. Green shifts should not be assumed to have the same established explanation. An unexpected color deserves an in-person assessment rather than a diagnosis from a photograph. No practitioner can guarantee that implanted pigment will never change in appearance.
What You Should Know
- A bluish appearance can reflect how light interacts with pigment beneath skin, not simply the original ink color.
- Placement, dot size, and healed contrast need to be evaluated together.
- Blue and green shifts should not be presented as equally established phenomena.
When to Seek Professional Advice
If your SMP looks unexpectedly cool-toned, arrange an assessment that considers healed skin, lighting, pigment history, and placement before agreeing to additional pigment.
