Due to the increasing popularity of tattoos as well as laser removal, technology has advanced quite a ways in the past five to ten years. This technology is improved to make it more efficient and less damaging on the skin. This is great news for people looking to remove tattoos, since they are now able to have a lower risk of adverse side negative effects.
The procedure that removes tattoos using lasers employs an intense burst of light energy that breaks down the pigments that are present in tattoos. Your body’s defense system slowly removes these particles in the course of. Each treatment following the initial one will break the ink particles further, until they are eventually removed by the body or are made transparent. This is the reason you’ll observe the tattoo fade faster in the 4-8 weeks following the removal procedure, because your body begins to slowly take away smaller pieces.
This may sound easy however, the technologies and processes which are involved are far more complex and require a deeper look to understand exactly the underlying mechanisms.
Skin’s three layers
When you’re tattooing or having one removed the process is directly involving the skin. It is important to know about the skin’s layers in order to comprehend what goes into tattooing as well as removal of tattoos.
The skin is comprised from three distinct layers: epidermis and dermis as well as the hypodermis.
What is the process for getting a tattoo? perform?
Before you take off the tattoo, you must to obtain a tattoo removal kit first.
Today the most popular method is the use of a tattoo machine, which inserts ink onto the skin using needles or several needles. It is punctured numerous times between 80 and 150 times per second.
The ink is first placed in the epidermis (top layer of skin) as well as the dermis (middle layer of the skin). After healing the epidermis that has been damaged regenerates eliminating any pigment. But, the ink remains in the dermis and epidermis boundary and makes the tattoo permanent.
Professional tattoos usually incorporate ink on the dermis while amateur tattoos are typically closer to the skin’s surface.
What are the most effective lasers used for tattoo removal?
For laser tattoo removal it is obvious that you will require a laser which is a device that produces the light in a focused beam.
For tattoo removal there are two major kinds of lasers employed.
QS laser is a Quality-Switched (QS) laser
Picosecond laser
QS lasers were among the first lasers to appear on the market and were was commercially used in the early 1990s.
They work by delivering an enormous amount of energy to a specific location, within a brief period in time (we’re talking nanoseconds, which is one-millionth of one second).
The Picosecond laser is the most recent advancement, having launched PicoSure being released in 2012 and PicoSure in 2012, and the more sophisticated PicoWay coming in 2015.
The term “picosecond” refers to the amount of time that the laser produces its energy. Picoseconds are one trillionth of seconds. This is 1,000 times more powerful than a nanosecond, the duration of the QS lasers.
The importance of wavelength and Fluence, as well as Repetition Speed and Spot Size Laser Tattoo Removal
1. Wavelength
Light is composed of various wavelengths.
The ideal wavelength that is used by the laser to eliminate the tattoo will be determined by the color of the ink used in the tattoo and the colour of the skin of the patient.
2. Fluency
Fluence is a measure of energy density. i.e. how much energy is available contained in the laser’s area.
More fluency could result in greater tattoo removal Derby. However it also runs the risk of damaging your skin. Therefore, it is essential to maintain fluence at a minimal level that allows you to attain the aim of eliminating the tattoo without causing any damage to the skin.
As the treatment progresses an increase in fluence is usually required since the density of ink reduces and tattoos get lighter.
3. Repetition rate
Repetition rate (RR) refers to the amount at which laser’s laser pulses flash in a single second, as determined by Hertz (Hz). 1 Hz equals 1 laser pulse every second.
Different tattoos require different repetition rates.
If the area being treated is smooth and wide, a large RR may be utilized which will reduce the amount of duration of treatment the skin.
In the case of an unorganized and detailed area an RR lower than necessary.
4. Size of the Spot
The size of the spot is determined by the size of laser light.
The larger the size of the spot the more deeply the laser’s penetration into the skin. But, it also demands more power (fluence) and therefore, the size of the spot utilized by a doctor is determined by several factors, including the size, location and color of the mark.
Picosecond laser vs QS laser
A picosecond laser is more effective in removing tattoos that QS lasers and lowers the chance of damage for the skin.
The shorter duration of the pulse produces a different impact upon the destruction pigment. It triggers an effect called a photoacoustic, in contrast to the photothermal employed for QS lasers. QS laser.
This breaks down the ink into smaller pieces to be absorbed to the immune system. the less heat results in less damage to tissues around it.
The speed increase also means that they are able to operate with less fluency (as stated earlier) to provide a more effective treatment.
The procedure of removal of laser tattoos
The first step to get the treatment you want with lasers is to conduct an examination of the patch. This involves the treatment of a small portion of your tattoo. You will then look for end points that are clinical like frosting. When the tests are successful, then you’ll be able proceed with the removal of your tattoo.
The practitioner begins by cleansing the area before using a cold machine to start numbing the skin. This helps to reduce the amount discomfort that can be felt throughout the process.
The laser is then placed against the skin, and emits intense light pulses. The laser’s light directly strikes the ink’s pigments that causes the ink to break in pieces, breaking them to smaller bits.
As we mentioned previously, when you use the QS laser, a photothermal process is created which causes the pigment and causes it to degrade. If you are using the picosecond laser, it employs a photoacoustic effects that is, it uses pressure to break the pigments.
It means the Picosecond Laser is much less in intensity than the QS and, since it doesn’t make use of heat, it’s less sensitive and less likely to cause damage to the skin.
The function that the immune system plays in the removal of laser tattoos
After the pigment has been broken down, it’s left to the immune system and body to finish the job.
The human body is equipped with specialized macrophages, cells that detect the presence of, ingest and eliminate the harmful bacteria or other bodies.
The cells will adhere towards the fragments of pigment, and begin the process to eliminate them using an process called the phagocytosis.
The process of lasering usually has to be repeated many times. This is because each procedure will only break down the ink enough and has to be absorbed through the body’s immune system prior to the time the laser is able to be used again.
If there is not enough time given between treatments The laser treatment will not have much impact. The usual interval of eight months between sessions was established through numerous clinical studies conducted by Candela Medical, the manufacturer of the PicoWay laser.
The laser utilized in tattoo removal is actually aiding the body to do its job.
It is likely that older tattoos generally have diminished as time passes. This is due to the fact that it is the bodies attempt eliminate the foreign pigment that was in the tattoo. This is why older tattoos may require less sessions than fresh tattoos.
The effect of the colour of your skin on removal of tattoos
Human skin contains melanin which affects its color. The higher the amount of melanin, more dark the complexion. This can also affect the color of the eyes and hair.
The quantity of melanin found in different skin types can affect the treatment of removal of tattoos.
An numerical scale has been developed that is known as The Fitzpatrick scale. It can be used to determine the right method of treatment for the person.
The greater the scale the greater the intensity of treatment is required that is why a higher amount of sessions is required. Its wavelength influences the severity of the treatment. Less intense wavelengths are more threatening than those with longer wavelengths.
For instance Types 1-3 of skin can be extremely aggressive. Skin type 4 is more aggressive and skin type 5-6 should be extremely low.
This is due to melanin’s an exceptional energy absorption rate. For example when you wear an outfit with a darker color during a hot day you’d feel warmer than if you were wearing light-colored clothing. This is because darker colors absorb more energy.
Thus, the more melanin one has the more energy gets taken up by the laser. You might think this would this would lessen the number of sessions but it actually causes skin discoloration.
So a more gentle method is required to prevent this outcome.
The effect of the colour of the ink on removal of tattoos
As we have discussed previously The wavelength of the laser can affect different colors. This is due to the fact that different colours draw different wavelengths, causing ink to break.
It’s crucial to ensure that the location you choose to go for tattoo removal uses a laser that emits the correct wavelength to match the hue of the tattoo.
Conclusion
Tattoos are an extremely popular means of self-expression But what happens when you’re ready to remove them? The process of removing tattoos is often lengthy, based on the color and the type of ink employed.
We’ve explored the impact that skin color and the colour of ink can have on the amount of sessions required to remove tattoos.
