SMP can cause infections or allergic reactions because it is a skin-penetrating tattoo procedure. Contaminated ink can cause infection even when the artist uses hygienic techniques, and some tattoo reactions appear long after treatment. These risks are established for tattooing generally, not as a specific SMP complication rate. Fever, pus, spreading redness, or worsening pain requires prompt medical evaluation. Follow the aftercare instructions already provided, but do not use routine aftercare or a studio follow-up as a substitute for medical care when warning signs occur.
What You Should Know
- Clean technique and safe products address different sources of risk.
- An initially uncomplicated result does not rule out every later tattoo reaction.
- Warning signs require medical evaluation rather than a cosmetic correction appointment.
When to Seek Professional Advice
Before treatment, ask about hygiene and the products being implanted. After treatment, seek prompt medical evaluation for fever, pus, spreading redness, or worsening pain instead of waiting for a routine studio review.
