Last few ThursdaysI was invited to listen to a laser talk by a very old laser manufacturing company Quanta System. This company has at least 30 years experience in creating medical aesthetic lasers of high quality with previously more focused towards OEM for other major suppliers of medical aesthetic supplies such as Syneron, Cynosure and a few others. I was surprised to see them promoting their own range since it was not common before. Besides, Delta Medisains was kind enough to invite me on a day that luckily I was pretty free and prior I had turned them down few times. Thank you Frances for the invitation, it was certainly interesting and educational.
The only problem I have now is that I realized, I did not take enough photographs to put into the blog, since I was more intrigue asking more and more questions. Nothing hypes me up more in the morning than learning about new technology. (Okay fine, hot Italian men do hype me up to, but that’s a different type of hype). By the way, the speaker was an Italian dermatologist, Dr Paolo Sbano (No, that was not the reason I got up early that morning, really was the laser company). He was really good at explaining the use of the laser, the difference between the 3 beams, combined treatments, side effects and how to avoid complications. From the way he was explaining I could see he was really passionate about his work, and he was pretty technical. Sorry Paolo, for the questions I bombarded you with but it was a really intriguing device.
So what is it really? It is actually a laser device that has multiple q-switch beams. There are 3 wave lengths, 532 nm (ND YAG), 694nm (Ruby) and 1064nm (ND YAG). Each wave length tackles different levels of the skin and the q-switch allows less thermal damage to the surrounding tissue. Therefore it is very effective in removing pigmented lesions such as tattoos and pigmentation. The 532 nm waves focuses more on red coloured pigment and shoots more superficially. The 694nm Ruby does more of green and blue, and the 1064nm gets rid of darker shades of pigments or tattoos. Yellow is in between the red and green, and they have also found lightening of yellow pigments as well. The device also has a fractional mode that allows more penetration, deeper and safer because you need less fluence of the more aggressive laser and thus complications and down time can be controlled. Rights, maybe it is getting a bit more technical here.
Quick explanation. Laser stands for Light Amplification by Stimulated Emission of Radiation. What it basically means is that if you have a medium, and you stimulate with high energy to form a beam of light, well that is laser. In all instances, laser can only be a single monochromatic beam. Therefore, you require different mediums to create different wave lengths. Usually in medical laser devices, we use crystals to produce the beam. ND YAG (Neodymium-Doped Yttrium Aluminium Garnet) produces two types of beams based on the amount of energy given to it, i.e. 532nm and 1064nm. Ruby is ruby (yes, that precious red stone that every woman would like to keep in their possession) also in solid state, usually in a rod and gives out the 694nm wave length. This explains why laser machines are so expensive, because of the quality of the medium used and also the assembling of the device that requires high grade mirrors and glass to avoid unnecessary reflections and excess heat built up in the device or the skin. And this is also why clinics who use real medical grade laser devices charge more than beauty salons. The device is at least 10x more than what a normal salon device cost. And there are differences in terms of results, even between laser makers themselves. You need to have played enough or researched enough to understand the differences. Yes, it is a specialised field. So if your doctor is not trained, they wouldn’t have a clue on how to use the device to its maximum potential whilst avoiding the unnecessary side effects of laser burns or post-inflammatory hyperpigmentation post treatment.
So what is q-switch? No, it is not a switch on the laser marked with a Q. Basically, it tells the doctor and manufacturer how the laser beam is being shot from the laser. The q-switch mode is a really fast nanosecond short pulse laser form that allows you to shoot the skin directly to the target depth with enough force to break the pigment targeted (remember, this is a pigment laser), but without the heat that comes with conventional method of shooting laser. Thus, it reduces downtime and there is less heat damage to the surrounding tissue. It became a hype in the past decade as a very safe method of shooting lasers with no downtime or severe side effects and is able to treat pigmented lesions and tattoos effectively. This however, was then founded to be not necessarily true and that there are emerging cases of hypopigmentation and scarring after using q-switch laser. Hence this is why proper training is required for doctors to avoid complications.
I’m really excited to try out this laser but the only problem is when will we finally manage to schedule a demo for me. My schedule has turned crazier every minute with so many activities in between. Personally, I still love to write and share my experiences. You can actually follow my account on Instagram to see what I’m up to @dr.marr . Will update more on this laser once the demo is done. Have a good weekend peeps.
