Episode 219 hosts Professor Syed Haq, a Cosmetic Physician from London, UK. Syed divides his time between preventative medicine & aesthetics. He has previously been an advisory board member for Ipsen, Allergan Aesthetics and is a Hugel Aesthetics KOL for Letybo.  In our mini series 'The Tox Talks', we feature expert injectors who have significant experience in using a particular brand of a botulinum toxin as well as teaching it's use to other injectors.  These episodes explore our guests experiences using that brand, the evolution of their injecting techniques and we get special insights into the subtle nuances of getting the best of out that particular toxin. In this episode we focus on a newly-launched product called 'Letybo', a toxin produced by Hugel Aesthetics based in South Korea. Letybo is also known as Botulax and has been used in the Asian market since 2009.  We explore: Syed's training and career to date His role as a consultant for several pharma companies & most recently Hugel Aesthetics His insights into how the use of toxins has changed over the years The science behind Letybo The difference between vacuum dried & freeze dried toxins Some of the key outcomes of the Letybo clinical trials Syed's thoughts on a toxin's protein load & the incidence of toxin resistance  Why the market needs more toxins Comparing units of different toxins - is this too simplisitc? How Letybo is reconstituted Why the depth of a toxin injection matters How a variety of factors can contribute to variable results  How to introduce a new toxin choice to your patients  What needles & syringes he prefers to use for toxins His thoughts on charging for toxins per area vs per unit   SUPPORT THE PODCAST: If you enjoy listening to IA every week and would like to help support the podcast in a small way, we have a simple donation option: Buy us a coffee   IA PATREON: Did you know that we have an online injectable education & business mentoring platform called 'IA Patreon'?
