Many people still have quite a few questions about tattoo removal, and today kaka will answer them one by one.
What is the principle of laser tattoo removal?
Whether it is tattoo removal, freckle removal, red blood removal, etc., all use the principle of photothermal selectivity. In short, lasers of different wavelengths are absorbed by different target chromophores. In the matter of tattoo removal, lasers of different wavelengths are aimed at pigment particles of different colors. When a specific pigment particle absorbs the energy of a specific laser, it will be blasted.
Under the microscope, the tattoo pigment is a large piece of ink of different colors, because the laser can blast the pigment particles of the tattoo pigment to a size that can be swallowed by human cells, and then these small scraps will follow. The normal metabolism of the human body is excreted by us.
I believe that when you see this, you may have a question, since we metabolize every day, why are tattoos not naturally metabolized?
First, the metabolism of dead skin only occurs in the epidermis, while the pigment of the tattoo is sealed in the dermis, and the dermis will not be renewed every day like the stratum corneum; cannot be swallowed.
Will laser tattoo removal work once?
Generally speaking, whether it is a Q-switched laser or a picosecond laser, it is difficult to have obvious effects at one time. Many people think that there is no change after doing once. This is not because it is useless (don't think that it is useful to have blisters) , After the pigment is dispersed, it cannot be seen by the naked eye at the moment. After a period of metabolism, you will find that the color becomes lighter.
Even a tattoo on Lun Lun's wrist with a single color, not deep layers, and a simple pattern could not be removed at one time.
Some professional tattoo ink particles will be relatively large, and a laser cannot completely smash them. From large particles to small particles, there are requirements for a single operation time and number of times.
Laser breaks up pigment
Phagocytic phagocytosis of pigment
How many times can laser tattoo removal be cleaned?
Generally, 4-6 times will have a more obvious effect. Most people need 6-12 times to wash it off, and it may be more.
It depends on the color, layer, time, skill level of the tattoo artist and the metabolic level of the tattoo artist. Generally speaking, the more colors, the deeper the layers, and the shorter the time, the more skilled the tattoo artist, and the more times needed. The better the metabolic level of the tattooed person, and the color is mainly black and blue, the fewer times the tattoo needs to be applied.
What kind of tattoos are easy to remove?
In terms of color, black, cyan, blue, and green are easier to remove, and red can also be removed with a dye laser, but yellow and orange are more difficult to remove, and the most difficult is white!
From a hierarchical point of view, the deeper the tattoo is or the more difficult it is to remove, the shallower is relatively easy.
In terms of tattoo time, the longer the tattoo is, the easier it is to remove it.
From the perspective of the technical level of a tattoo artist, the more skilled a tattoo artist is, the more difficult it is to wash a tattoo. The easiest thing to wash is the crooked pattern that a child who is ignorant uses a pen to poke himself on his arm in order to play cool.
Does laser tattoo removal hurt?
The epidermal numbing cream will be applied before the tattoo, so when it comes to the tattoo, normal people can tolerate it, but it will feel a little tingly. The degree of pain will vary depending on the part, and the more sensitive parts will feel more intense. In addition, if the tattoo layer is deeper, it will also hurt a little, but it is basically tolerable.
Is there a recovery period for laser tattoo removal?
In most cases, there is no recovery period, and no change can be seen just after the treatment. The color of the tattoo will become lighter as the body metabolizes, but it may also scab. At this time, just follow the normal laser postoperative care process with a recovery period. .
