Due to the increasing popularity of tattoos as well as laser removal, the technology has advanced an impressive amount over the past five to ten years. It has also been improved to make it more efficient and less damaging to skin. This is great news for people looking to remove tattoos, because they can have a lower risk of negative side adverse effects.
The procedure that removes tattoos using lasers employs an intense burst of light energy that breaks down the particles of ink that are found in tattoos. Your body’s defense system gradually eliminates the ink particles in the course of. Each treatment following the initial one will break down the particles of ink a little further, until they are eventually eliminated by your body or turn transparent. This is why you’ll observe the tattoo fade faster in the 4-8 weeks following the removal procedure, because your body begins to slowly take off the smaller pieces.
This may sound easy however, the processes and technology that take place are much more complicated and require a deeper investigation to comprehend what’s happening.
Three layers make up the skin
If you’re planning to get a tattoo or having one removed the process is directly involving the skin. It is important to know about the skin’s layers to understand what goes into tattooing as well as removal of tattoos.
The skin is comprised 3 layers including epidermis and dermis as well as the hypodermis.
What is the process for getting a tattoo? do the job?
Before you can remove the tattoo, you must to obtain a tattoo removal kit first.
Today the most popular technique is to use the use of a tattoo machine, which inserts ink onto the skin using needles or several needles. Skin is punched several times between 80 and 150 times in a second.
The ink is first placed in the epidermis (top layer of skin) as well as the dermis (middle layer of the skin). When healing occurs the damaged epidermis begins to regenerate and rids itself of any pigment. However, the ink is in the dermis and epidermis boundary and makes the tattoo permanent.
Professional tattoos usually incorporate ink in 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 require a laser an instrument that emits the light in a focused beam.
For tattoo removal Derby there are two major kinds of lasers employed.
Lasers that are quality-switched (QS) laser
Picosecond laser
QS lasers are the first lasers to appear on the scene , and were was commercially used in the early 1990s.
They work by delivering an enormous amount of energy to an isolated area, in a relatively short amount duration (we’re talking nanoseconds, which is one-millionth of one second).
The Picosecond laser is the most recent advancement, having launched it being introduced in the year 2012, followed by PicoSure in 2012, and the more sophisticated PicoWay due to be released in the year 2015.
The term “picosecond” refers to the amount of time that the laser produces its energy. Picoseconds are one trillionth of one second. It’s 1000 times faster than a nanosecond. the duration of a QS laser’s pulse. lasers.
The importance of wavelength The importance of Wavelength, Fluence, Repetition Speed and Spot Size Laser Tattoo Removal
1. Wavelength
Light is composed of various wavelengths.
The wavelength at which the laser for removing the tattoo will be determined by the color of the ink used in the tattoo and the skin colour of 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. However it also runs the risk of damaging your skin. It is therefore essential to maintain fluence at a sufficient level to reach the objective of getting rid of the tattoo without causing any damage to the skin.
Through the course of treatment an increase in fluence is typically required as the density of ink decreases , and tattoos are lighter.
3. Repetition rate
Repetition rate (RR) refers to the amount that 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 that is being treated is flat and broad, a high RR could be employed to reduce the duration of treatment the skin.
In the case of an area that is detailed and uneven an RR lower than necessary.
4. Size of the Spot
The size of the spot is the size of laser light.
The larger the size of the spot the more deeply the laser can penetrate the skin. However, it needs more energy (fluence) and therefore, the size of the spot used by a professional is based on various factors, such as the size, location and the colour that the tattoo is.
Picosecond laser vs QS laser
A picosecond laser is more effective in removing tattoos that QS lasers, and minimizes the risk of injury on the skin.
The longer duration of the pulse produces a different impact in the degrading of pigment. It triggers the photoacoustic effect in contrast to the photothermal employed for this QS laser.
The ink is broken up into smaller pieces to be absorbed to the immune system. the lower heat levels cause less harm to the tissues around it.
The speed increase allows them to work with less fluency (as stated earlier) to provide a more effective treatment.
The procedure of removal of laser tattoos
The first step towards getting the treatment you want with lasers is to conduct an examination of the patch. It involves the treatment of a small portion of your tattoo. You will then look for areas of end-points that can be considered clinical, like frosting. When the tests are successful, then you’ll be able to proceed with the removal of your tattoo.
The doctor will begin cleaning the area, and employing a cold air device to begin numbing skin. This will reduce the amount of discomfort that can be felt during the procedure.
The laser is held against the skin and releases intense light pulses. The laser’s light directly strikes the ink’s pigments that causes the ink to break and break to smaller bits.
As previously mentioned, when you use the QS laser, a photothermal process is created that heats the pigment and causes it to degrade. When you use 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 powerful than the QS, and since it doesn’t make use of heat, it’s less sensitive and less prone to harm the skin.
The importance of immune systems in the removal of laser tattoos
After the pigment has been removed, it’s left to the immune system and body to complete the rest of the job.
Human bodies have specialized macrophages that can detect and ingest the harmful bacteria or other bodies.
The cells will adhere with pigmented fragments and start the process of eliminating themthrough the process known as the phagocytosis.
The process of lasering usually has to be repeated several times. This is due to the fact that each treatment will only break down the ink enough and has to be removed through the body’s immune system prior to the time the laser can be used again.
If there is not enough time given between treatments The laser treatment is unlikely to have any 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 used in tattoo removal is actually helping the body perform its job.
You’ll notice that older tattoos generally have diminished with time. The reason for this is that your body’s attempt to eliminate the foreign pigment that was in the tattoo. This is why older tattoos may require less sessions than fresh tattoos.
The effect of skin colour on removal of tattoos
Human skin contains melanin that affects the colour of skin. The higher the amount of melanin, it’s darker skin. It also affects the color of the eyes and hair.
The quantity of melanin found in different skin types affects the process of removal of tattoos.
An numerical scale has been designed that is known as The Fitzpatrick scale. It can be used to determine the best method of treatment for the patient.
The greater the scale is the less aggressive the treatment will be which means a greater number 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 less aggressive and skin type 5-6 is very gentle.
It is due to melanin having an extremely high rate of energy absorption. In other words when you wear an outfit with a darker color during a hot day it will feel warmer than when you wear light-colored clothing. This is because darker colors take in more energy.
Thus, the more melanin one has the greater amount of energy absorption by the laser. It is possible to think this means that this will lessen the number of sessions, however it actually causes skin discoloration.
A more gentle method is required to prevent this kind of effect.
The effect of the colour of the ink on removal of tattoos
As we have discussed previously In the previous paragraph, the wavelength of the laser affects different colors. The reason for this is that different colours draw different wavelengths, which causes the ink to break.
It’s crucial to ensure that the location you are going to get tattoo removal uses a laser that has exactly the right wavelength for the color of the tattoo.
Conclusion
Tattoos are an extremely popular means of self-expression However, what happens if you’re looking to get them removed? The process of removing tattoos is often lengthy, based on the color and the type of ink employed.
This article has explored the effect that skin colour and ink color affect the amount of sessions required for removal of tattoos.
