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 dis...

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 rela...

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 a...

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...

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...

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.
