How Laser Tattoo Removal Works

Due to the increasing popularity of tattoos as well as laser removal, the technology has advanced an impressive amount in the past five to ten years. It has also been improved to make it more efficient and causes less harm on the skin. This is great news for people looking to have tattoos removed since they are now able to have a lower risk of adverse side negative effects.

The procedure that removes tattoos using lasers employs the power of a concentrated beam of light energy that breaks down the particles of ink that are found in tattoos. It is the body’s system of defense that gradually eliminates the ink particles as time passes. Every subsequent one will break down the ink particles more, until they’re eventually eliminated by your body or turn transparent. This is why you’ll notice the tattoo becoming less visible in the four to eight weeks following an elimination session, since 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 investigation to comprehend what’s happening.

Skin’s three layers

When you’re tattooing or having one removed The process involves 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? perform?

Before you can remove an ink mark, you have to first get one.

Today the most commonly used technique is to use tattoo machines that inject ink onto the skin using the use of needles or multiple needles. Skin is punched numerous times with a frequency of between 80-150 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 and rids itself of any pigment. But, the ink remains hidden below the dermis and epidermis boundaries and makes the tattoo permanent.

Professional tattoos generally inject ink on the dermis while more amateur tattoos typically closer to the skin’s surface.

What are the most effective lasers used for tattoo removal Derby?

For laser tattoo removal is a given, you require a laser which is a device that produces the light in a focused beam.

When it comes to removal of tattoos there are two major kinds of lasers utilized.

Lasers that are quality-switched (QS) laser
Picosecond laser

QS lasers were among the first to hit the market and were was commercially used in the late 1990s.

They work by delivering huge amounts of energy to an isolated 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 due to be released in the year 2015.

The word “picosecond” is used to describe the time during which the laser produces its energy. Picoseconds are one trillionth of seconds. It’s 1000 times more powerful than a nanosecond, the duration of a QS laser’s pulse. 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 for removing the tattoo will be determined by the color of the ink used in the tattoo and the colour of the skin of the person receiving treatment.

2. Fluency

The term “fluence” refers to energy density. i.e. what is the energy level contained in the laser’s area.

A higher level of fluency can lead to greater tattoo removal. 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 objective of getting rid of the tattoo without causing damage to the skin.

As the treatment progresses the fluency will increase. usually required since the density of ink decreases , and tattoos are lighter.

3. Repetition rate

A 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 skin being treated is smooth and wide, a large RR may be utilized which will reduce the amount of duration of treatment the skin.

If it’s an unorganized and detailed area in which there is a lot of detail, a lower RR will be needed.

4. Size of the Spot

The size of the spot is determined by the radius that the beam laser emits.

The larger the size of the spot is, the more the laser can penetrate the skin. However, it needs more energy (fluence) and therefore, the size of the spot used by a doctor is determined by various factors, such as the size, location and color that the tattoo is.

Picosecond laser vs QS laser

A picosecond laser performs better in removing tattoos that QS lasers, and minimizes the risk of injury on the skin.

The shorter duration of the pulse is a different influence upon the destruction pigment. It creates an effect called a photoacoustic, in contrast to the photothermal employed in QS lasers. QS laser.

The ink is broken up into smaller particles that can be absorbed through the immune system. the less heat results in less damage to tissues around it.

The higher speed allows them to work with less fluency (as previously mentioned) to ensure a successful treatment.

The procedure of removal of laser tattoos

The first step to get an application of lasers to your tattoo is conduct an examination of the patch. This involves the treatment of a small portion of your tattoo, and then looking for areas of end-points that can be considered clinical, like frosting. In the event that the procedure is successful you’ll be able proceed with the removal of your tattoo.

The doctor will begin by cleansing the area before using a cold machine to begin numbing skin. This helps to reduce the amount discomfort that may be felt during the procedure.

The laser is held against the skin and releases flashes of light that are rapid. The laser’s beam directly hits the pigments in ink that causes the ink to break and break to smaller bits.

As we mentioned previously, when you use the QS laser, a photothermal process occurs that heats the pigment, causing it to breakdown. If you are using the picosecond laser, it makes use of a photoacoustic effect which means it makes use of pressure to break up the pigments.

The picosecond laser is much less powerful than the QS, and since it doesn’t make use of heat, it is less sensitive and less prone to harm the skin.

The function of immune systems in the removal of laser tattoos

After the pigment has been removed, it’s left to the body and the immune system to complete the rest of the job.

The human body is equipped with specialized macrophages that can detect the presence of, ingest and eliminate the harmful bacteria or other bodies.

The cells will adhere with pigmented fragments, and begin the process of eliminating themthrough an process called Phocytosis.

The lasering process is usually required to be repeated many times. This is because each procedure just breaks down the ink enough and has to be removed from the system of the immune system, before it can be used again.

If there is not enough time allowed between treatments the treatment with laser is unlikely to have any impact. The usual interval of interval of 8 weeks of time between treatment 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.

You’ll notice that older tattoos generally have lost their color with time. The reason for this is that it is the bodies attempt eliminate the pigmentation that is foreign to the tattoo. This is why older tattoos may require less time than new tattoos.

The effect of skin colour on removal of tattoos

Human skin contains melanin that affects the colour of skin. The more melaninthere is, more dark the complexion. This can also affect the color of the eyes and hair.

The amount of melanin present in different skin types can affect the treatment of removal of tattoos.

An numerical scale has been designed that is known as”the Fitzpatrick scale. This scale can be used to determine the best procedure for an patient.

The greater the scale the greater the intensity of treatment is required which means a greater number of sessions is required. Laser wavelength influences the intensity of the treatment. The shorter wavelengths are more aggressive than those with longer wavelengths.

For instance the skin types 1-3 could be extremely aggressive. Skin type 4 is more aggressive and skin type 5-6 is very gentle.

It is due to melanin having an extremely high rate of energy absorption. For example in the event that you were wearing an outfit with a darker color during a hot day you’d feel warmer than when you wear an edgier shirt. This is because darker colors take in more energy.

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 outcome.

The effect of the colour of the ink on removal of tattoos

As mentioned earlier 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 are going to get tattoo removal is equipped with the correct laser that has the correct wavelength to match the hue of the tattoo.


Tattoos are a very popular method of self-expression However, what happens if you’re ready to remove them? The process of removing tattoos may take a long time, based on the color and the type of ink employed.

We’ve explored the effect that skin colour and ink color can have on the amount of sessions required to remove tattoos.
