Tattoo Removal St. Petersburg
Q-Switched lasers come in many forms but are most commonly known for their use in tattoo removal. The concept of Q switched is that energy is built up and delivered by dumping all of the energy in one packet. This allows the chromophore (tattoo pigment) to absorb the energy causing it to fragment. Smaller fragments of tattoo pigment are then taken up by the macrophage white blood cells in the skin and taken away slowly eliminating the tattoo.
The success of tattoo removal is dependent on many variables including size, color, smoking status, and whether or not it was professionally done or done by an amateur. Larger tattoos require more treatments for obvious reasons. Green, blue, and black inks are the easiest tattoos to remove while red, orange, yellow and white are more difficult. The laser Dr. Newman uses can deliver both 1064 nm wavelengths and 532 nm wavelengths to treat both dark and lighter pigments. Smokers have been found to have reduced efficacy in tattoo removal presumed to be due to impaired white blood cell function which is essential in taking away the smaller fragments of pigment after laser energy is delivered. Amateur tattoos are easier to remove because the pigment is less dense and placed more superficially into the skin. Finally, older tattoos are easier to remove because they are typically fading meaning less pigment is present.
Laser tattoo removal is not painless. There can be some discomfort but is typically tolerable in short intervals. Aftercare may include applying Vaseline or Bacitracin ointment to the treated area and avoiding sunbathing or swimming. Treatments can be repeated in 4 to 6 weeks. Laser tattoo removal can create scar in the process of treating the tattoo because heat can cause thermal injury. Patients should not attempt tattoo removal without understanding and accepting this risk.
