Objectives: The picosecond laser offers a much shorter pulse duration of just 1012 seconds and combines photothermal with photomechanical effects on the target tissue with higher effects and less side effects due to heat. This allows to treat some complicated indications better than with nano second technology. We want to Show which indications do better qwith Pcio technology
Introduction: Traditional laser modalities for pigment and tattoo removal operate on pulse durations in the nanosecond domain, which is too long to effectively break all ink colours and particle sizes into small enough particles. Picosecond (10-12) lasers -due to their shorter pulse lengths - lead to quicker heating of the target and consequently, more effective tattoo clearance.
Materials / method: In classic indications like black, brown, dark blue pigment and tattoos PicoCare hits the targets in two ways: photothermally chromophore specific plus photmechanically . This combination allows a much faster and more complete clearing in fewer sessions with less pain than the with ns lasers.
The toning effect with low fluence and high frequency multiple shot and multiple pass laser energy delivery of mainly 1064nm in combination with the picosecond pulse provides dual benefits. to fracture melanosomes an dto create laser uinduced optical breakdown.
Results: Multicolour tattoos usually need various wavlengths and multiple sessions and still might not clear completely.In several studies the picosecond laser achieved 75-percent clearance in just 1 or 2 treatments instead of 5-10 sessions.with the addition of newer wavelengths allowing for more indications. Wavelengths of 670, 650 or 585 allow the treatment of vascular disorders respectively indications where vessels are involved. This is true for mixed melasma with increased vascularisation or Verrucae planae and vulgares
Conclusion: PicoCare is a tool which is effective and cost effective.These examples show new prospects for the picosecond laser and as the use of these lasers become more widespread we will find more ways of establishing their potential.
