Lasers in Skin

Today, Mike and Lisa investigate the most common concerns surrounding laser hair removal, as discussed in various online forums. They explore the concept of paradoxical hypertrichosis, synchronised hair growth, and the effects of laser treatments on hair colour, including the potential for hair to appear grey or lighter. 

KEY TAKEAWAYS

There is a common misconception that laser hair removal can cause paradoxical hypertrichosis, where hair grows in areas that previously had none. However, many reports of increased hair growth after treatment are likely due to synchronised hair growth, which occurs when hair follicles are treated w...

In today's episode, Mike and Lisa look at the complexities of safely and effectively treating deeper skin tones, particularly those with higher melanin concentrations. They discuss the importance of understanding how melanin affects laser treatments, noting that darker skin absorbs more energy, which can lead to increased risks of cellular damage and pain. Both Mike and Lisa challenge common misconceptions about using lower fluences for darker skin, advocating instead for higher fluences combined with enhanced cooling techniques to achieve optimal results.

In this episode, Mike and Lisa delve into a concerning trend in the laser and IPL industry: the potential capping of fluence output by machine manufacturers. They discuss recent experiences shared by practitioners who found their machines unable to deliver the higher fluences promised in their manuals, raising questions about the implications for treatment efficacy. Mike and Lisa advocate for the need to empower users with the ability to access the full potential of their devices, rather than imposing arbitrary limits that could hinder results.

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.

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.
