Why Tattoos Are Difficult to Remove
There are several techniques which are claimed to be able to remove tattoos on the skin, but in fact tattoos can not just disappear without leaving a trace. Why can tattoo last tens of years and are very difficult to remove?
According to eHow, a permanent tattoo are very difficult to remove from skin. One cause is because they have to inject tattoo ink into the inner skin layer called the dermis, the skin layer beneath the epidermis.
If it is still at the epidermal layer, the tattoo can be removed, butt fact is that tattoo is injected into the deepest layers of skin.
If viewed from the lining, the top layer of skin is called the epidermis. This layer consists of five layers, namely the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum and stratum corneum.
The two layers above, namely the stratum lucidum and stratum corneum, are flat and dry skin cells, resistant to water and functions to protect the skin. Skin cells will change and begin to peel in the stratum basale to the surface of the skin in a month.
Well, because it aims to create lasting images, finally drawing a tattoo must be injected to penetrate deeper layers of the epidermis.
Not just that, there is another effect if the inner skin layer are torn.
Tattoo ink injection in the skin layer will trigger the reaction of the body immune system, which would make the tattoo last on the skin longer.
The cells in the skin that attack foreign substances called phagocytes (eating cells) will swallow and consume the ink particles.
Then, fibroblasts (cells that produce collagen) will lock the phagocytes with tissue under the skin, just below the epidermis that fills the dermis, approximately 1 millimeter from the surface of the skin. This allows ink to stay on the skin layer for years.
According to Medic8, there are some reason that makes it difficult to remove tattoos, which are the tattoos color used and the human skin color.
Certain tattoo colors like black, green and brown would be more easily removed than red, orange and white. And one color tattoos like black or blue is much easier to remove.
For skin color, people with darker skin color will experience more difficulty in removing tattoo than people with lighter skin color.
In people with dark skin there is a risk of skin scarring or loss of natural skin pigment, although it does done by using the laser tattoo removal techniques.
