In this episode, Mike and Lisa delve into a recent critique of their training methods regarding laser hair removal, specifically addressing concerns raised by a laser supplier about their promotion of higher fluences and external cooling techniques. Mike & Lisa clarify the science behind pulse widths, fluences, and the importance of targeting stem cells rather than just the hair itself. Mike and Lisa also touch on the implications of using higher fluences on handpiece longevity and the overall effectiveness of treatments, encouraging practitioners to prioritize results and client satisfaction.

KEY TAKEAWAYS

• The relationship between pulse width and fluence is crucial in laser hair removal. A higher fluence can lead to longer pulse widths, but the key factor is ensuring that the energy delivered is sufficient to heat the stem cells effectively, regardless of the pulse width.

• Pre-cooling the skin with ice packs before treatment can significantly reduce pain and the risk of unwanted side effects, such as blistering and pigmentation changes. This allows practitioners to use higher fluences safely.

• The denaturation time, which is the time required to irreversibly damage the target cells, is more critical than the pulse width alone. The temperature and duration of exposure are what ultimately determine the effectiveness of the treatment.

• The podcast discusses criticism of their training methods, particularly regarding the use of higher fluences. They argue that using higher fluences with proper cooling leads to better results, even if it may reduce the lifespan of the handpieces.

• There are common misconceptions in the industry about starting with low fluences and gradually increasing them. The podcast emphasizes the importance of starting at the correct fluency from the beginning to achieve effective results without unnecessary delays.

BEST MOMENTS

"We promote skin cooling, higher fluence, which in diodes equals longer pulse width. They're saying that will be bad for the treatment because they believe you should have a short pulse width."

"If you use a lower fluence, that means you're firing in less energy. And less energy means lower temperatures. Lower temperatures mean you need much longer times to cook the cells."

"The temperature of the hair is, like I said, pretty much irrelevant. What is important is getting the right amount of energy into the hair."

"If you're going to end up sitting there with a lot of disgruntled clients... then that's not good for your business or your reputation."

"The higher the fluence, the shorter the time you need to denature the cells. And that's why the pulse width becomes unimportant."

In this episode, Mike and Lisa interview Caroline McLean, an advanced skin practitioner from Skinology in Glasgow, who shares her extensive 20-year experience in the industry. They discuss Caroline's unique approach to using IPL for pigmentation, which contrasts with Mike and Lisa's established protocols. Caroline elaborates on her combination therapies, including the use of a cold laser bionic and CO2 treatments.

KEY TAKEAWAYS

• Caroline McLean utilises a unique IPL protocol for treating pigmentation, which involves higher fluence settings and double passes, contrasting with traditional methods. This approach allows for immediate darkening of the pigment, indicating effective treatment.

• Cooling the skin before, during, and after IPL treatments is crucial. Caroline emphasises the need for thorough cooling to minimise erythema and edema, ensuring client comfort and optimal results.

• Clients are advised on aftercare, including cooling the skin, avoiding acids and retinoids, and using recovery balm. This helps manage expectations regarding the healing process and potential side effects like tenderness and swelling.

• Caroline integrates various treatments, such as LED therapy (Dermalux) post-IPL, to enhance healing and monitor skin reactions. This holistic approach combines skincare, lifestyle factors, and treatment modalities for better outcomes.

• A significant part of Caroline's practice involves educating clients about their skin conditions, treatment processes, and realistic outcomes. This includes discussing the importance of skin preparation and the potential need for multiple sessions to achieve desired results.

BEST MOMENTS

"I will usually do two passes and kind of cross hatch them. I want to see that pigment getting darker."

"I don't treat darker skin tones, so I wouldn't treat any sort of Asian skin tones or any mixed skin tone with an IPL."

"The biggest combination therapy is combining your skincare with your treatments with your lifestyle and your holistic sort of side of it as well."

"I want to know how they're going to respond to something. If they then come back to me and their skin is not recovering, then that's on me."

"I think it would have to be my severe inflammatory acne clients, being able to help somebody heal their skin is pretty amazing."

In today's episode, Mike and Lisa dive into the fundamental concepts of laser physics through a fun "Explain Like I'm Five" format. They explore key terms such as fluence, pulse width, and wavelength, breaking down complex ideas into simple analogies. Mike explains how fluence, measured in joules per square centimeter, is crucial for achieving effective results in laser treatments, while pulse width is likened to the duration of a bus journey delivering energy to the skin.

KEY TAKEAWAYS

• Fluence refers to the concentration of energy delivered to the skin during laser treatments, measured in joules per square centimeter. It is crucial for achieving effective results in procedures targeting hair follicles, blood vessels, and pigmentation.

• There is a minimum threshold fluence that must be exceeded for a treatment to be effective, as well as a maximum threshold to avoid causing damage to surrounding skin tissues. Finding the right range of fluence is essential for successful outcomes.

• Pulse width (or pulse duration) is the length of time that energy is delivered to the skin. It can vary significantly depending on the type of laser used, and it does not directly correlate with the reaction time of the tissues being treated.

• Wavelength determines the color of the light used in treatments and is measured in nanometers. Different wavelengths penetrate the skin to varying depths, which affects their effectiveness in targeting specific structures like hair follicles or blood vessels.

• The concept of useful penetration depth combines both wavelength and fluence. It is important for ensuring that the energy delivered can effectively reach and treat the intended target within the skin, especially for deeper structures.

BEST MOMENTS

"Fluence is basically how concentrated the energy is on the skin surface, in a spot."

"To me, fluence is king. That's the main driver of pretty much all these reactions."

"So fluence is basically your make or break for any of these treatments that we are doing?"

"Pulse width is just a technical thing designed into the laser, but it doesn't actually translate into the cooking or the denaturation process within the tissues."

"There's no point the bus of photons reaching the target if they're all tired and they can't do anything."

In this episode, Mike and Lisa delve into the complexities of online forums related to laser treatments, including laser hair removal and tattoo removal. They express their concerns about the often toxic environment of social media, where misinformation can spread easily and new practitioners may take inaccurate advice as gospel. The duo emphasise the importance of conducting thorough research and seeking multiple perspectives before accepting any information found online.

KEY TAKEAWAYS

• Social media forums, especially those related to laser treatments, can provide both valuable information and misleading advice. It's important to verify information from multiple sources rather than accepting it at face value.

• When seeking information, it's advisable to consult scientific literature and various reports from different researchers to form a well-rounded understanding, rather than relying on a single source.

• Healthy debate and discussion in online forums are crucial for community learning. However, some groups may suppress differing opinions, which can hinder the sharing of accurate information.

• It's important to recognise that even experts can be wrong. Updating knowledge based on new evidence is a sign of growth and should be embraced.

• Many individuals in these forums are seeking support and guidance. It's essential to foster a respectful and helpful environment rather than engaging in ego-driven arguments.

BEST MOMENTS

"I'm just getting a bit sad about some stuff online and want to put it out there, really, see your thoughts."

"If you do see stuff on the Facebook forums or any kind of forum, do your own research to back it up or get some different opinions."

"The problem is that if people are just being deleted or blocked, then the argument is essentially being shut down."

"I'm happy to say that previously, a couple years ago, my information was incorrect. I've updated it and now the information I'm putting out there, hopefully, is correct."

"Some people are just like arguing in the comments about who's better."

In this week's episode, Mike and Lisa look into the intriguing relationship between waxing and laser hair removal treatments. They explore the traditional belief that waxing should be avoided before laser treatments due to the risk of removing the hair target, but Mike presents a compelling argument based on the biology of hair growth phases. They discuss the importance of melanin in targeting hair follicles and suggest that waxing may actually enhance the effectiveness of laser treatments by reducing pain and minimizing harmful plume exposure for operators.

KEY TAKEAWAYS

• Traditionally, it has been advised not to wax before laser treatments because waxing removes the hair, which is the target for laser energy. However, recent discussions suggest that waxing may not be as detrimental as previously thought, and could potentially be beneficial.

• The hair growth cycle consists of three main phases: anagen (growth), catagen (transitional), and telogen (resting). Only hairs in the anagen phase can be effectively targeted by laser treatments, as they contain melanin, which is necessary for the laser to work.

• Melanin is the target chromophore for laser hair removal. While it is typically found in the hair shaft, significant amounts of melanin are also present at the base of the hair follicle, which can be targeted even if the visible hair is not dark or fully developed.

• Waxing can reduce pain during laser treatments by removing visible hair that could generate heat and discomfort. Additionally, it minimizes the amount of plume (burnt tissue) released into the air, which can be harmful to both clients and operators.

• There is speculation that waxing may help synchronize hair growth cycles, leading to more effective laser treatments. However, more research and real-life examples are needed to confirm this theory and determine the best protocols for combining waxing and laser treatments.

BEST MOMENTS

"So the interesting thing that I realised while studying all this was that the new hair shaft is growing or starts to grow in anagen 3. It's not fully melanised until late in anagen 3."

"So, any hair we can see that's not in catagen or telogen must be in late anagen. And that's good for us."

"If you hit those with laser IPL light, it makes no difference. If it's an anagen, it means the follicle is already in the subcutis, in the fatty tissue."

"If you wax them before you do the treatment, then immediately after the treatment, there's no visible hairs at all."

"So I suspect that if you were to wax and then treat with laser IPL, you'd probably have a hair-free environment for quite some time."

In this episode, Mike and Lisa delve into the anticipated new regulations for laser treatments set to be introduced in Scotland in 2026. Drawing from Mike's extensive experience in the industry since opening the world's first tattoo removal clinic in 1989, they discuss the current regulatory landscape, the potential qualifications required for practitioners, and the importance of medical oversight for certain treatments. There is confusion surrounding existing regulations and a need for clarity as the industry evolves.

KEY TAKEAWAYS

• New regulations regarding laser treatments in Scotland are expected to be proposed in 2026, with ongoing discussions about the qualifications required for practitioners.

• The first laser clinic for tattoo removal opened in Glasgow in 1989, and despite expectations for new regulations over the years, significant changes have yet to be implemented.

• Current recommendations suggest different qualification levels for various laser treatments, with Level 4 for IPL and laser hair removal, Level 5 for laser tattoo removal, and higher levels potentially requiring medical oversight.

• There is a lack of clarity regarding what constitutes "medical oversight" in the context of laser treatments, leading to confusion among practitioners about compliance and training requirements.

• Those currently using lasers should consider obtaining the necessary qualifications before the new regulations take effect, as failure to comply could result in business disruptions and insurance issues.

BEST MOMENTS

"When I first started in this industry about 375 years ago. We opened the world's first clinic in Glasgow, right? It was the first clinic in the world to offer Q-switched ruby laser treatment of tattoos."

"It appears to me that they don't take these things with any sort of serious level of priority. Which is a real shame because it has become a bit of a wild west out there."

"Our advice right now is just wait and see what's going to happen. If you know that you are doing these treatments, look into getting your full qualifications if you've not got them yet."

"The current setup suggests that if you're using CO2 lasers for skin treatments, then you need to have medical oversight. So there needs to be some sort of a medically qualified person in the loop somewhere."

"If you decide to go ahead and use the lasers outside of the requirements of the regulations, then your insurance probably will be void. If something goes wrong, your insurance company will just walk away."
