Foreword by Dr. Mário Trelles
"When one decides to write a book (not an easy task, to be sure), I believe that the author decides to use free verse and to relate personal experiences. It is like pouring water into a fountain, adding experiences without them being noticed as being added to the existing water. Or, at least, one could even tint that water a little with the color of what we communicate, but knowing that with the passing of time the new hue would disappear. But, if one has the courage to start writing a technical text, the task is much more difficult, because first it involves reading-studying-reviewing and finally capturing the personal profiled version of a knowledge, in such a way that it can easily reach the more readers, the better.
The wording of textbooks is often “petrified” and we hardly notice the changes that are included in them to update them, because science requires time to assimilate and, furthermore, validate them. The change would have to be great in order to remove the bases of what is known to the point that it would allow us to discard “what is written and recognized”, with contributions that, where possible, explain and can be interpreted in a non-confusing way.
So, when I read this book, I felt my enthusiasm refreshed, as I revisited a familiar topic, worked with a different approach, which helped me find enlightening paths (without the clumsy atavisms of repeating and repeating lessons), which could well serve me in my frequent academic occupation.
I believe that by recommending its reading I will serve above all interested patients who wish to know more about how the laser can remove hair and, even more so, if they wish to learn how it is possible for its action to develop by pointing to a chromophore that "belongs to it".
When reading Sabrina Gomes' book, I found a very mature text, in which it is clear that the author did not allow herself to be tempted by imagination and, on the contrary, offers the fruit, the synthesis of her knowledge. The development of the book is intelligent and makes good sense, as it explains laser hair removal and hair removal performed with intense pulsed light systems in a pleasant, accessible and fun way.
Its reading is completely understandable (despite the long list of synonyms that the word may have) as it is a clear and easy-to-read manuscript in which the author - with great ingenuity - makes difficult and tedious topics, such as the physical foundations of lasers, atomic transitions, selective absorption phenomena or extended thermal therapeutic action, appear transparent and accessible. And also for the reader who has not previously had contact with the therapeutic properties of lasers and/or has not received explanations of how light acts in its hair removal action.
To insist, the book is pleasant and instructive and it would even be advisable for each patient to have the opportunity to read it if they wish to understand, at least in broad strokes, how light is not only capable of eliminating hair but also treating and curing, which until a few years ago was difficult to do; diseases that with treatments obtained (most of the time) grotesque solutions, which today can be avoided by giving the patient the opportunity to experience satisfaction, this feat is of recognized importance when considered in the list of symptoms that the individual must have to feel healthy.
This is what the World Health Organization means when it refers to self-esteem and the satisfaction of being able to look in the mirror and feel happy with the image you see reflected back. And this is relevant, because photoepilation as an elective treatment is not just an act that aims at beauty; it is about finding the satisfaction of looking better and liking yourself.
My most sincere congratulations to Sabrina for her work, along with my best wishes for her success in her occupation, accompanied by her interest in learning and learning, without rest."
