Recurring mistakes in tattoo removal. A case series

Area of Science:

• Dermatology
• Aesthetic Medicine
• Laser Physics

Background:

• Tattoo removal utilizes selective photothermolysis to destroy pigment particles.
• This process requires specific laser parameters: short pulse durations (nanoseconds) and high intensities.
• Over 10% of Western populations have tattoos, increasing demand for safe removal methods.

Observation:

• A study examined 12 patients treated with suboptimal laser parameters for tattoo removal.
• Patients presented with adverse effects including hypo- and hyperpigmentation.
• Scar formation was also diagnosed at the treatment sites.

Findings:

• The applied laser pulse durations were significantly longer than required for selective photothermolysis.
• Low light intensities failed to destroy tattoo pigment particles effectively.
• Improper parameters led to pigment heating and non-specific thermal injury to surrounding skin tissue.

Implications:

• Millisecond pulse lasers and low-intensity light sources are unsuitable for effective and safe tattoo removal.
• Adherence to precise laser parameters is crucial to prevent adverse outcomes.
• Further research into optimal laser settings for tattoo pigment ablation is warranted.
