Whatever your reason for getting the tattoo, it probably falls into the category of “seemed like a good idea at the time”. We’ve all been there in some way or another, you’re not alone. You got inked and now you want it gone.
Luckily, modern advancements in laser technology have made it possible to safely and effectively remove permanent ink from the skin.
How Lasers Work to Remove Tattoos
The lasers used in the tattoo removal process breaks down these artificial skin pigments, thus removing the tattoo from the person’s skin. However, there are certain requirements that must be met to ensure that only the targeted skin area is treated with laser and must not damage surrounding tissue. The requirements are:
- Penetration of the laser should be sufficient enough to reach the tattoo pigment
- The color of the laser must correspond to the absorbability of the pigment. For example, red lasers are used to treat green skin pigments
- Duration of the laser last must be precisely timed to avoid scarring and burning of surrounding skin tissues. In tattoo removal, laser blasts should only last nanoseconds
- Sufficient energy is required for the laser to break down tattoo pigments. If energy is too high, it could damage the skin tissues. If it is too low, no pigment fragmentation will occur.
Determining Which Laser is Right for You
The gold-standard laser used for laser tattoo removal today is called a Q-switched laser. In order to target the different color pigments in a tattoo, the selection of the appropriate Q-switched laser must be determined.
Q-switched lasers work by delivering energy at such a rapid speed that it breaks or splits the ink up into tiny particles. Your bodies filtration system (or immune system) then comes in to carry off the debris.
There are various types of Q-switched lasers used to remove tattoos, depending on the color of the skin and the tattoo pigment. Multi-colored tattoos require two or more types of lasers to effectively remove them. The lasers are usually identified by the medium used to create the wavelength, which is determined by measuring its nanometers (nm).
Q-switched Lasers Deliver Energy — FAST!
Most Q-switched, both Yag and Alexandrite lasers deliver laser energy in nanoseconds, however there is new Alexandrite laser on the market that delivers energy in picoseconds. A nanosecond is equal to one billionth of a second. Wikipedia further defines a nanosecond by saying “one nanosecond is to one second as one second is to 31.7 years.” Now that’s fast!
Conversely, a picosecond is one trillionth of a second. The theory is the faster the energy is delivered it breaks the tattoo ink up into smaller particles making it easier for the body to filter it away. There is not enough clinical data available to show that a picosecond delivery versus a nanosecond delivery really makes that big of a difference. At best it could save you a couple of sessions, but this too is not clear at this point.
A medical professional will be able to determine which laser or hand pieces combination are needed to effectively remove your tattoo. They will take into account several factors including your skins natural pigment and the pigments in the ink. Dark blue and black inks respond really well to laser treatments, lighter pigments like white, reds and pinks can be harder to remove.
About the Q-switched Yag Laser
The Q-switched Yag laser has been the preferred laser of choice and really the “gold standard” in laser tattoo removal since laser tattoo removal came on the scene. It is the only laser suitable for all skin types and dark skin in particular, as the light it creates is not absorbed by the melanin (skin pigment) and therefore less likely to result in hypo or hyper-pigmentation.
Unlike other lasers, the Yag overcomes the issue of excessive melanin absorption, targeting the ink and not the melanin. It is used to effectively remove all ink colors, but particularly targets darker inks like blue, black or red pigments in all tones.The Yag laser will be used at each of your tattoo removal appointments, if you have color in your tattoo a dye hand-piece will also be used at some point during your treatments to target each specific color.
About the Q-switched Alexandrite Laser
The Q-switched Alexandrite laser is also used for tattoo removal, but less frequently. The Alexandrite or “Alex” laser can only safely treat skin types I-IV so this excludes darker skin types from being treated with this laser without serious risk of burns, hyperpigmentation and even scarring. The Alex laser creates a red light that is absorbed well by green and dark ink pigments. Similarly to the Yag, it will be necessary to use dye hand pieces to treat colors.
Q-switched Lasers Used at WIFH for Tattoo Removal
Q-switched Frequency-doubled Nd:Yag: 532 nm – this type of laser works best for red and orange tattoo pigments.
Q-switched Ruby: 694 nm – this laser emits red light, which is highly effective in removing green and dark tattoo particles. However, this laser can also cause serious changes in the skin’s natural pigmentation structure. Too much usage of this laser can cause unwanted spots and blotches on all skin types except white/lighter skin tones.
Q-switched Alexandrite: 755 nm – rated as the weakest of all types of Q-switch lasers, the Alexandrite laser only works best on green tattoo pigments. It is not effecting against, red, orange, and brown. The Alexandrite laser can also be used to remove black and blue ink particles. Since it is a weak laser, it does not cause any unwanted changes in the skin’s natural pigmentation.
Q-switched Nd:YAG: 1064 nm – best for dark skin types since it uses near-infrared light, which is not absorbed by melanin.
Laser Types Matter & Side Effects May Occur
As with any cosmetic procedure, laser treatment is not without risks and potential side effects. The potential side effects include hypo or hyper-pigmentation, darkening of the tattoo (caused by changes in the chemical composition of certain inks), blistering, allergic reactions and scarring. The likelihood of of experiencing any of these things is a variable. Blistering can be a normal part of the laser tattoo removal process and in most cases should not leave you with a scar.
However, it is imperative to seek treatment from an experienced provider that will supply you with aftercare instructions and care should you experience a complication. They should also thoroughly explain the numerous factors that influence the outcome of treatments and they will help you to set realistic goals and avoid unwanted side effects.
You needn’t have to live with a constant reminder of impaired judgement from your past. With a little help from a laser, you may be able to restore your skin to a blank canvas, or at least a minimalist painting. Schedule your free consultation today to discuss the right treatment for you.
