Lasers in Skin

In today's episode, Mike and Lisa delve into the critical topic of skin cooling during laser treatments. They discuss the importance of maintaining optimal temperatures to prevent pain and thermal damage to surrounding tissues, particularly collagen. Mike explains the thermodynamics behind laser energy absorption and the necessity of using effective cooling methods, such as ice packs, to draw heat away from the skin. The duo also addresses common misconceptions about air and cryo cooling systems,

In this episode Mike and Lisa sit down with Dr. Marc Reid, author of "You Are Not a Fraud: The Scientist's Guide to Imposter Syndrome." Together they delve into the complexities of imposter experiences, exploring their origins, manifestations, and strategies for managing them. With personal anecdotes and insights from Dr. Reid's research, including a survey of over a thousand participants, the discussion highlights the commonality of these feelings among professionals, particularly during career

In this very first episode of the Lasers in Skin podcast, physicist Mike Murphy and his daughter, Lisa McMahon, introduce themselves and share their unique backgrounds in the world of lasers and skin treatments. Mike recounts his journey from studying physics and astronomy to pioneering laser tattoo removal and becoming a laser protection advisor. Lisa reflects on growing up surrounded by lasers and her transition from a corporate HR role to working alongside her father in the laser training

In this episode, Mick and Lisa dive into the fascinating world of vascular removal treatments, specifically focusing on their favourite methods using IPL and long pulse YAG lasers. Lisa shares her excitement and detailed protocol for treating blood vessels, discussing the importance of pre-cooling the area, selecting the right fluence, and the technique of applying gel to the IPL tip. They explore the nuances of treating different types of vessels, including stubborn cherry angiomas and deeper leg

In this episode, Mike and Lisa dive into the concept of fluence, a critical factor in laser treatments. They explain fluence as the concentration of energy delivered to the skin, emphasising its importance in achieving successful results for various procedures like hair removal, tattoo removal, and treating blood vessels. They also cover related terms such as pulse width and wavelength, using relatable analogies to simplify complex physics concepts. KEY TAKEAWAYS Fluence refers to the

In this episode, Mike and Lisa dive into a lively question-and-answer session, addressing a variety of topics related to laser technology and safety. They discuss common misleading claims made by laser suppliers, particularly regarding hair removal capabilities and output power, emphasising the importance of understanding fluence over mere wattage. The duo also shares humorous anecdotes, including Mike's penchant for dad jokes and a lighthearted debate about safety goggles versus ice pack cooling

ABOUT US 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
