    Regulations (Again!)
    Feb 18 2026
    Keywords regulations, small businesses, aesthetic treatments, licensing, training standards, injectables, safety, enforcement, local authority, accountability Summary The conversation delves into the upcoming regulations affecting aesthetic and laser businesses in the UK, focusing on their implications for small businesses, safety standards, licensing, and training requirements. The speakers discuss the need for proper enforcement and accountability within the industry, emphasizing the importance of consumer protection and the challenges that may arise for practitioners and clinics as new standards are implemented. Takeaways The new regulations aim to protect consumers and ensure safety in aesthetic treatments. Licensing and training standards are crucial for practitioners in the industry. Remote prescribing for injectables poses significant risks and should be regulated. Training academies must be held accountable for the quality of education they provide. Local authorities will play a key role in enforcing new regulations. Small businesses may face challenges in adapting to new licensing requirements. Proper oversight is necessary to ensure compliance and safety in clinics. The conversation highlights the need for a recognized standard in training and practice. Good practitioners should welcome regulations that improve industry standards. Future discussions will be necessary to assess the impact of these regulations. sound bites "There should be a recognized standard." "We need proper oversight for safety." "We should revisit this after May."

  • The Uncomfortable Truth About Laser Hair Removal

    The Uncomfortable Truth About Laser Hair Removal
    Feb 12 2026
    In this myth-busting deep dive into the science of aesthetics, Lisa McMahon and physicist Mike Murphy take laser hair removal out of the ‘magic wand’ category and into reality. Plot twist: the hair isn’t the star of the show, it’s just the messenger. The duo breaks down the surprisingly complex world of the hair follicle, spills the tea on stem cells and the dermal papilla (DP), and explains why so many treatments shrink hair instead of kicking it out for good. Whether you’re a seasoned pro or just laser-curious, this episode mixes physics, biology, and a few “wait, WHAT?” moments to reveal why timing the follicle’s growth phase is the real secret to long-lasting results. KEY TAKEAWAYS The hair shaft acts as a conduit that contains melanin to absorb light energy and convert it into heat, but the actual goal is to dismantle the follicle structure. For effective permanent removal, the laser must successfully target and destroy the stem cells in the bulge and the dermal papilla (DP* at the base of the bulb. As a hair follicle grows during the Anagen phase, the bulb descends deeper into the skin (towards the subcutis), making it progressively harder to kill as it gets further from the surface. If a treatment uses insufficient fluence (energy), it may only partially damage the DP. The follicle then regenerates with fewer cells, resulting in a thinner, lighter hair. Most hair visible on the surface is in the Catagen or Telogen phase, meaning it lacks a matrix and cannot be effectively treated. The true targets for permanent removal are actually invisible beneath the skin during early-to-mid Anagen. BEST MOMENTS "The hair is not the target. The hair is a conduit to essentially dismantle the follicle." "If you kill all the stem cells in the bulge but you leave behind some DP cells, then the DP can regenerate some stem cells." "The matrix can have up to five times the concentration of melanin compared to the hair... that makes it a really, really good target for light." "Catching the follicle at the right time is quite tricky because if you don’t catch it at the right time, the DP might just be too deep." "Science doesn’t lie; we just keep moving around a bit." 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.

  • Why Is Laser Hair Removal Still Guess Work?

    Why Is Laser Hair Removal Still Guess Work?
    Feb 5 2026
    In this episode, Lisa and Mike, dive into the common frustrations surrounding laser hair removal and why results can vary so significantly between individuals. Joined by Lisa’s newborn, Baby Bryan (Rosha), they discuss how subpar training and a lack of fundamental biological understanding within the industry contribute to inconsistent outcomes. KEY TAKEAWAYS Many laser technicians are taught to ‘under-treat’ or follow rigid, incorrect protocols, leading to more sessions with fewer results. Energy output on a screen may not match what is actually being delivered; machines naturally lose efficiency over time and require regular professional calibration. Different body areas have different growth cycles (e.g., leg hair has a very long anagen phase), meaning treating every area at the same four-week interval is often ineffective. Thicker hairs tend to be deeper in the skin. Effective treatment requires enough energy (fluence) to reach the follicle's base, which varies by body site. Firing multiple low-energy shots (e.g., three shots at 10 Joules) does not equal the depth penetration of one high-energy shot (e.g., one shot at 30 Joules). BEST MOMENTS "You pass your test, and then you're free to drive on the roads, and that's when you learn to drive properly. It’s the same in the laser game." "A lot of people out there, they don't know what they don't know." "Calibration is really only valid for that day. All machines, they all lose efficiency over time." "If you're targeting hair with a 'sub-lethal threshold', you will not kill the follicles. They will regenerate, they'll grow back, and the hairs will be finer." "The higher the fluence, the deeper it goes. It's as simple as that. And the deeper you can penetrate into the skin, the more follicles you'll hit."
