    What's Important About Continuous Training?
    Jul 10 2025
    In this episode, Lisa and Mike discuss the critical topic of continuous training in the laser and aesthetic industry. They take a look at some alarming stories of clinics potentially providing inadequate training to technicians, leading to poor treatment outcomes for clients, particularly in laser hair removal. They highlight the importance of reputable training and the need for practitioners to understand the science behind their work, and also touch on various qualifications, including VTCT and ITEC, and emphasize the significance of ongoing professional development to ensure safety and efficacy in treatments. KEY TAKEAWAYS Continuous training is crucial in the laser and skin treatment industry to ensure technicians are knowledgeable and skilled in using equipment effectively, which directly impacts client results. There are significant concerns regarding the quality of training provided at some clinics, leading to poor treatment outcomes for clients, such as excessive sessions without satisfactory results. If technicians are not achieving good results, the responsibility lies with the management and owners of the clinics, who must ensure their staff are properly trained and equipped to provide effective services. Misinformation can easily spread within the industry, often from trainers who may not have the correct knowledge, which can lead to practitioners applying incorrect techniques or advice. When selecting a training provider, it is essential to research their credentials, ask about their training sources, and ensure they have a solid reputation to avoid investing in inadequate training that may not meet future regulatory standards. BEST MOMENTS "So yeah, allegedly, what always came out that people believe is what's happening is that technicians in these companies are being either told to do this or just not taught properly." "If they're not generating good results, then that's the responsibility of the managers and ultimately the owners of the clinic because they're supposed to provide a service." "It's making people think laser hair removal doesn't work. It's actually giving everybody quite a bad name, which isn't ideal for us." "You can have the best laser on the planet and if you're not using it correctly, you won't get good results. Simple as that." "This is just kind of coming into highlighting the importance of training and getting reputable training." 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.

    In this episode, Mike and Lisa return to their Explain Like I'm 5 series to explore the origins of lasers. Starting from Einstein's concept of stimulated emission in 1917 to the creation of the first laser by Theodore Maiman in 1960, Mike and Lisa break down complex concepts such as monochromaticity, coherence, and non-divergence, making them accessible to listeners of all ages. They discuss the mechanics of how lasers work, including the roles of gain mediums, mirrors, and the process of stimulated emission. KEY TAKEAWAYS Lasers operate based on the principle of stimulated emission of photons, a concept introduced by Einstein in 1917. The acronym LASER stands for "Light Amplification by Stimulated Emission of Radiation." A typical laser consists of a gain medium (which can be a crystal, gas, or liquid), two mirrors (one fully reflective and one partially reflective), and a power source to stimulate the gain medium. The mirrors help amplify the light by reflecting photons back and forth. For a laser to function effectively, a population inversion must be achieved, where more atoms are in an excited state than in a ground state. This is necessary to ensure that stimulated emission can dominate over spontaneous emission. Different types of lasers exist, including solid-state lasers (like Nd:YAG and ruby lasers), gas lasers (like CO2 lasers), and diode lasers. Each type has unique properties and applications, with diode lasers being particularly versatile due to their ability to generate various wavelengths by combining different semiconductor materials. BEST MOMENTS "LASER means, LASER is an acronym, stands for Light Amplification by the Stimulated Emission of Radiation. In this case, radiation being light energy." "So wait, why did he invent it? Because he could." "So coherence basically means that all the photons, they're all doing the same thing, they've all got the same wavelength or frequency, they're all moving in the same directions." "If you don't have enough electrons in the right metastable state, then the whole thing will eventually just kind of peter out." "The problem is that some of these drops in energy states will not generate new photons, but they'll generate phonons."

  • Laser Tattoo Removal - 'Mythconceptions'

    Laser Tattoo Removal - 'Mythconceptions'
    Jun 26 2025
    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."
