Optical Dissolution of Dermal Pigments
Establishing the principles of selective photothermolysis and the acoustic fragmentation mechanisms used for pigment removal.
Laser tattoo removal is based on the principle of Selective Photothermolysis. This requires a specific wavelength of light to be absorbed by a target (chromophore) in a duration shorter than its thermal relaxation time.
The Photoacoustic Effect
When a high-energy pulse hits a pigment particle, it undergoes rapid thermal expansion. This creates a sonic shockwave (photoacoustic effect) that shatters the particle into fragments small enough for the lymphatic system to remove.
- »Wavelength (nm): Must match the color of the ink (e.g., 1064nm for black, 532nm for red).
- »Pulse Duration: Nanoseconds vs. Picoseconds. Shorter pulses produce higher peak pressure with less collateral heat.
- »Spot Size: Determines the depth of penetration; larger spots reach deeper into the dermis.
Patrick's Perspective
"Overseeing tattoo removal in my past studios gave me a deep respect for dermal biology. Using light to create sonic shockwaves is an intense procedure. It requires more respect for the body's natural limits than almost any other procedure we do."
