The topic of laser hair removal is by far one of the most wanted to touch since the beginning of the blog. I think it is one of the issues that most concern women, not to say that it is possibly the most. Personally I have gone through different types of lasers, with very different experiences in all cases. All this has led me to decide to dedicate a specific section under the tag Hair Removal that I hope will be to all of help to learn together and share experiences.
For today I come with a global entry on the subject as an introduction and with the collaboration of Laura , reader and blogger in Love Yourself and Makeup . From here thank you for the research you have done for us, as well as for the resolution of all the doubts that have arisen to me along the way as we mounted the entrance. We have been preparing this entrance for many months, so we are very excited. To top it all off we are lucky that she is a beautician by profession and specialized in the technique, so we can certainly create a very interesting debate around this subject so crucial for a multitude of women.
A LITTLE HISTORY
The beginning of laser technology begins with Einstein when heformulatesthe concept of “stimulated light emission” in 1900. Maiman in 1959 was the precursor of applying these theories in the treatment of the skin, thus developing the first laser Ruby , which applies a monochromatic light of 694 nanometers.
Soon after, in the year 1963, the dermatologist Leon Goldman initiated the treatment with ruby laser in different cutaneous pathologies .
In the 80’s Anderson and Parrish developed the principle of selective photothermolysis, contributing to greatly improve laser technology and giving a great boost to its use. The key point of this concept is the destruction of the hair follicle without damaging the surrounding structures.
In 1995 Goldberg used the Yag neodymium laser to depilate. From this moment on, comparative studies are beginning to demonstrate the effectiveness of the laser in depilation.
PHOTODEPILATION AND LASER ARE THE SAME?
When we speak of photodepilation and laser, it is customary to confuse terms. In both cases we refer to the depilation thanks to the light transformed into heat, ie: PHOTODEPILATION = INTENSE PULSED LIGHT (IPL) AND LASER What we usually catalog as photoepilation is the pulsed light system or IPL. When in fact the term photoepilation encompasses all forms of laser hair removal (pulsed light, ruby laser, alexandrite, diode, yag …). LASER stands for “ Light Amplified by Stimulated Emission of Radiation” meaning that it is a device capable of extending a beam of light as a result of a stimulated and controlled action, Which is called selective photothermolysis . One of the differences between the laser and the IPL is that in the first the beam of light is collimated, which means that it goes in a direction and in parallel, and in the ipl is not collimated: there is divergence of light, has Different directions. That is why the IPL covers a greater amount of hair and skin but is less specific, while the laser acts on areas and groups of more specific hairs, being more precise.
Lastly, it is important that you know that the very light and very dark phototypes are the only ones in which the photoepilation may be ineffective, so it is appropriate that these cases be evaluated beforehand by a professional that indicates if it could be fit .
In my opinion, epilation itself is not a widespread need, since many people have virtually no hair or it is scarce or even invisible. In order for us to understand each other, it is not worth it in all cases. But it really is a matter of hygiene for a lot of people and in many other cases it is an aesthetic problem that can even be a source of stress and anxiety . Not all people have to worry about this issue, but many dedicate a significant time of our lives to the depilation (be it traditional blade, wax and its variants). If we add up that time invested, in the end it can become a rather striking sum. In my opinion and after my past and current experiences with the laser, as long as one can afford it and the epilation occupies a significant space of time in your life, it can be a great relief and a perfect solution.
