Why is the laser wavelength important for tattoo removal?

  Just like every patient is different, every tattoo removed by laser tattoo is unique.

  Professional laser practitioners want to remove any tattoo, regardless of the ink color in the design. For this, you need multiple laser wavelengths to complete the job.

  The removal of tattoo inks of different colors requires different laser wavelengths.

  All of these are based on the concept of light absorption. ——Some tattoo pigments absorb certain wavelengths of light better than others. In order to provide effective tattoo removal treatment, you need to ensure that the laser wavelength you use is completely absorbed by the tattoo ink you are treating.

  Our goal = focus.

  The working principle of tattoo removal is to decompose the tattoo ink particles in the skin. To achieve this, the laser generates pulses on the tattoo and directs light energy to the ink. The energy is absorbed by the tattoo ink particles and instantly shattered into tiny fragments.

  If the ink does not absorb the laser, the ink will not break…and the tattoo will not be removed.

  Light energy can be visible or invisible, depending on its wavelength. When light energy is visible (wavelength between 390 nm and 700 nm), we treat it as colored light.

  Different objects absorb and reflect light of different wavelengths in different ways. Tattoo ink has the same effect. For example, a red tattoo absorbs all visible colors except red. The tattoo looks red in our eyes because it reflects red and not other colors.

  Therefore, if your goal is to smash the ink in a red tattoo, you should not treat it with red light because it will reflect all the light without absorbing energy.


  Common Wavelengths for Tattoo Removal The most widely used wavelengths for tattoo removal include 1064 nm, 532 nm, 694 nm and 755 nm. Each of these wavelengths can handle a specific set of tattoo ink colors:

  Among these wavelengths, the most common ones are the wavelengths -1064 nm and 532 nm produced by Nd:YAG lasers.

  Some laser companies provide laser machines that combine multiple laser wavelengths into a two-in-one or three-in-one system, such as Astanza duplication and Trinity. These systems are usually the first choice for serious practice because they allow for versatility of treatment and higher efficacy.

  Nd:YAG laser | 1064 nm, 532 nm.

  Nd:YAG laser can generate wavelengths of 1064 nm and 532 nm.

  The wavelength of 1064 nm is very suitable for removing black or dark tattoos, because the light of this wavelength can be well absorbed by the black ink. Since the ink color most commonly used by tattoo artists is black, the wavelength of 1064 nm is the most commonly used laser wavelength for tattoo removal.

  The wavelength of 532 nm is the most effective wavelength for red ink and other warm colors (including purple, orange, yellow, and brown). The wavelength of Nd:YAG is 1064 nm and 532 nm, and it can handle various colors of ink. Generally speaking, Nd:YAG laser can treat 90-95% of tattoos, because red and black are the most popular tattoo ink colors. The two Nd:YAG wavelengths are safe for all skin types and allow the most effective tattoo laser removal procedure.

  Ruby Laser | 694 nm 694 nm.

  Ruby laser wavelength is very suitable for removing blue-green ink, as well as cyan, turquoise and lemon green tones that are difficult to remove with Nd:YAG laser alone.

  In addition to dealing with these rare tattoo colors, the 694 wavelength is also excellent in removing black ink.

  Industry leaders tout laser systems that combine Nd:YAG laser technology and ruby ​​laser technology because of their versatility and ability to handle almost all ink colors.

  Alexander Morphing Laser | 755 nm.

  Similar to the 694 nm wavelength of the ruby ​​laser, the 755 nm wavelength of the emerald laser is also an excellent complementary wavelength for processing green, blue and black inks.

  Like the ruby ​​laser, the emerald laser is also a special wavelength, which can be added to the Nd:YAG system, but its versatility alone is not enough to be the only laser for tattoo removal. In addition, buyers should know that since the wavelength of 755 nm is a red beam, it is impossible to perform any processing on the red ink.

  Things to note

  There are some other wavelengths that can be used to remove tattoos-namely 585 nanometers and 650 nanometers. Although these wavelengths may also be good choices for removing blue and green inks, they cannot be produced at the same power as the other wavelengths mentioned in this article.

  These wavelengths are produced by using dye-impregnated cell phone filters, which results in lower energy levels than directly produced by lasers. Installing a 585nm or 650nm dye mobile phone on the laser will make you mistakenly think that you have a useful tool for tattoo removal. If you tell them you can treat a tattoo that you really can’t treat, you will damage your reputation among patients, so be careful before you pass on the hype.

  Choose the right wavelength for your practice.

  Wavelength is one of the most important factors to consider when buying a laser machine. The ability of each wavelength is different, so it is important to have tools to treat patients’ tattoos.

  For all tattoo colors, it is important to have three full power wavelengths:-1064 nm for black ink, 532 nm for red warm ink, and 694 nm or 755 nm for blue and green ink.

  Laser treatment is more than just laser tattoo removal. Recently, Self Magazine published a wonderful article about the use of lasers by dermatologists in various cosmetic procedures. This article focuses on how to use various types of lasers (and which ones) to treat common problems that dermatologists see in practice. Dermatologists often recommend laser surgery for problems including brown spots and discoloration, redness, wrinkles, acne scars, stretch marks, and of course, tattoo removal.

  Kally Papantoniou, MD, a dermatologist at Advanced Dermatology PC, said, “Nothing can really replace the effect of laser on the skin. For young people, you can use sunscreen, which is a good skin care plan. Or make chemical skin changes everywhere.” She continued, “But you have reached the point where you want to restore the privileges you once had.” She said this is a place where lasers can be used. They can create different worlds. But if you want to make the most of it, you need to know what you are entering. Then, the article began to discuss various lasers for different treatments. Overall, this article is comprehensive and provides a useful overview of the possibilities of laser skin care.

  Laser therapy training and certification.

  One of the highlights of this article is that what we want to pay attention to is the training and certification of the personnel performing the laser project. Most states allow non-medical professionals to perform laser surgery, but it is important to fully understand the laws in your state. The most common rule is that off-site doctors must act as “medical supervisors” and delegate tasks to laser technicians and supervise them.

  However, as pointed out in the article, please make sure you go to a legitimate provider and know who is performing the treatment. The importance of this step is one of the reasons we established the New Face Laser Academy, which aims to train and certify personnel who will perform laser tattoo removal procedures. The New Face Laser Academy is the world’s first laser training program dedicated to tattoo removal. Training is provided in selected locations around the world, including the United States (providing courses) and internationally.

  After the training, each New Look Laser College training customer will receive three certifications to recognize their new background in laser training and be authorized to use q-switched lasers to perform laser tattoo removal and other cosmetic laser procedures.

  It is wise to seek certification or ask the person treating you what kind of training they have received. If you are considering a laser tattoo removal business, it is also a good idea to be certified and know how to use lasers properly before treating any patients.
