TECHNOLOGY COMPARISON

Picosecond Lasers vs Q-Switched Lasers (Nanosecond)

Understand the difference in pulse durations. Picosecond lasers shatter pigment via photomechanical disruption, while nanosecond lasers use photothermal effects.

Picosecond Lasers

Pros

  • ✓Trillionths of a second pulse duration
  • ✓Shatters ink/pigment into much finer dust
  • ✓Requires fewer sessions with less collateral heat damage

Cons

  • ×Equipment is massively more expensive
  • ×Can cause pinpoint bleeding (petechiae)

Q-Switched Lasers (Nanosecond)

Pros

  • ✓Industry standard for over 20 years
  • ✓Highly effective for dark, amateur tattoos
  • ✓More affordable treatments

Cons

  • ×Higher heat delivery increases risk of scarring
  • ×Struggles with stubborn colors like green and blue

Clinical Verdict

Pico Lasers represent the evolution of pigment removal, offering faster clearance with less thermal damage, though Q-Switched remains a highly capable baseline tool.
