Le LASER en esthétique : tout ce qu'il faut savoir !

"Hello, I have an appointment for laser treatment!" - "Uh... yes, but which one?" ⚡ When dermatology aims to remove something from the skin, we can use tools that remove everything in their path (scalpel, liquid nitrogen, electrocoagulation, etc.) or machines that emit precise energy to target a specific area. Indeed, since the invention of televisions, microwave ovens, and cell phones, the practical applications of these wave fields have been constantly multiplying. In dermatology, we don't use gamma or Wi-Fi wavelengths, but rather other wavelengths that are absorbed by specific elements of the skin's biological tissue. For example, the skin pigment, brown, contained in a spot or a hair, is strongly absorbed by a wavelength of 755 nm. While blood, hemoglobin, and the red pigment in skin absorb even more energy at 532nm and even have a second maximum absorption peak at 595nm And that's really cool because, as a result, lasers act a bit like homing devices, concentrating their action on a specific element in the skin, sparing as much as possible all the other tissue components. As you can see, there are A LOT of lasers in dermatology! And what's more, several wavelengths can work on the same target... And on top of that, several brands of machines of varying quality (safety and effectiveness ratio!!) exist for each wavelength. In short, it's a real headache to explain to you each time the choice we make... and above all, STOP ASKING THE RECEPTIONIST "HOW MUCH DOES THE LASER COST?" Because it doesn't mean anything… 😂 _______ Music: Bensound - https://www.bensound.com _______ Feel free to subscribe, turn on notifications 🔔, and leave a comment with topics you'd like to see explored further. _______ 🗞️ To stay up-to-date, find me on: ➜ Instagram:   / dr_marie_jo.  . ➜ TikTok:   / dr_marie_jourdan   _______ See you soon! 💫
