There are several techniques that claimed to remove tattoos in the skin, but in fact the tattoo could not just disappear without leaving a trace. Why can tattoo lasting decades and difficult to be eliminated?
Reporting from eHow, Wednesday (18/08/2010), a permanent tattoo is so difficult to remove from skin. For one thing, the manufacture of tattoo ink should be injected into the skin layer called the dermis, the skin layer below the epidermis.
When still in the epidermal layer of the tattoo can be removed, but tattooing is injected into the deepest skin layers.
When viewed from the lining, the top layer of skin called the epidermis. In this layer consists of five layers, namely the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum and stratum corneum.
Two layers above, namely the stratum lucidum and stratum corneum, is flat and dry skin cells, resistant to water and serve to protect the skin. Skin cells will change and begin to peel in the stratum basale to the skin surface in a single month.
Well, because it aims to create lasting images, eventually drawing the tattoo must be injected more deeply penetrating the epidermal layer.
Not finished only there, there are other effects if the skin layer in 'torn apart'.
Tattoo ink injection in the skin layer will trigger the reaction of the immune system (immune) body, which ironically would make the tattoo stuck on the skin longer.
The cells in the skin that attack foreign substances called phagocytes or phagocytes (eating cells). This eater cells to engulf and consume the ink particles.
Then, fibroblasts (cells that produce collagen) will lock the phagocytes with the tissue under the skin, just below the epidermis that meet the dermis, approximately 1 millimeter from the surface of the skin.
This allows ink to stay on the skin layer over the years.
Reporting from Medic8, there are some more reasons that make the tattoo is hard to remove the tattoos that used color and skin color of the tattoo.
Tattoo colors such as black, green and brown would be more easily removed than the red, orange and white. And a tattoo of one color like black or blue is much easier to remove.
For skin color, people with dark skin will be more difficult to remove tattoos than those with lighter skin color.
In people with darker skin there is the risk of scarring or loss of natural skin pigment, although done using laser techniques.
