About this listen

 In today's episode, Mike and Lisa discuss the physics and biology behind the process, explaining how lasers interact with tattoo ink to create steam bubbles that facilitate ink removal. Mike shares his extensive experience in the field, dating back to 1986, and clarifies common misconceptions about tattoo removal technologies, including the differences between Q-switched and picosecond lasers. The episode also addresses myths surrounding frosting, the significance of sound during treatments, and the challenges of removing various ink colours. KEY TAKEAWAYS The process involves using lasers to heat tattoo ink particles rapidly, causing them to absorb energy and create steam bubbles that break apart the surrounding cells, allowing the ink to disperse. The most common lasers used for tattoo removal are Q-switched and picosecond lasers. Q-switched lasers deliver energy in nanosecond pulses, while picosecond lasers deliver energy in shorter, picosecond pulses, which can lead to slightly more effective ink removal. Frosting, the white or grey appearance on the skin after laser treatment, is often misunderstood. While it can indicate a successful treatment, it is not a necessary clinical endpoint, especially as treatments progress. The idea that a cracking sound during treatment indicates effective tattoo removal is incorrect. This sound can occur when the laser is used improperly, leading to unnecessary skin damage. While lasers can technically treat all ink colours, the energy required for certain colours, like yellow, may be too high and could damage the skin. White ink is particularly difficult to remove due to its reflective properties. BEST MOMENTS "When you hit a tattoo with laser energy, the ink in the tattoo will absorb some of that energy, will heat up very, very rapidly and will quickly exceed the boiling point of water." "The lasers we use are either Q-switched, which deliver nanosecond pulses, or picosecond lasers. These pulses are extremely short, and you have to do that to generate the extremely rapid temperature rise." "I found that, for particle sizes down to something like five microns in size, there wasn't really any significant difference, but below five microns, there was some appreciable difference." "If they come in for a consultation, they're like, does it hurt? I'm like, well, yeah... it does hurt. Use ice pack cooling to try and reduce the pain as much as we can." "The problem is that your spot size is so small, your energy density is so high that you will damage the skin. No two ways about it." ABOUT THE HOSTS Mike began his career in medical lasers in 1986 with a physics degree and a post-grad in bioengineering. He helped develop the scar-free removal of tattoos using a Q-Switched Ruby Laser in Glasgow, and the world's first IPL system. Known well in the industry for his hard truths, no BS attitude and logical answers. As the author of three books, articles for medical journals, a well read blog, a Laser Protection Advisor and contributor to the BMLA, Mike is the Laser Guru. Lisa's claim to laser fame is being Mike's daughter. Growing up with lasers and never avoiding a physics lesson from her Dad, it was natural to enter the industry. Leaving a corporate career with a baby to jump into self employed life came with challenges. Despite that Lisa has been well recognised for her teaching style, practical tips, bringing the compassion to the science, and laser mentoring.
