Even often overlooked, skin is your body’s largest and fastest growing organ. It is only recent that we started taking care of our skins. Just half a century ago, bathrooms and showers were not in all houses and conditions of living did not put skin moisturizer and facial treatments as a priority. However, skin needs many layers that to achieve its sensitivity and do the job of a protecting frontier; keeping everything from the outside, outside and everything from the inside, inside. The three main layers are; epidermis, which is the top layer that you see, dermis which is thicker and subcutaneous fat which is the bottom layer.
Some allergies are mostly respiratory such as dust, but in the majority of cases, allergies will also reflect on your skin. Jewelry can cause many allergies also called metal hypersensitivity. If you do not buy silver or gold, you may have experienced another type of metal. If your new earrings make your earlobes feel itchy or if bracelets leave a rash on your wrist, you might be allergic to nickel. It is extremely common especially since nickel is a part of so many everyday life objects such as jewelry but also coins, keys, tableware, zippers and cell phones. Because of various properties such as strength and an awesome heat resistance, that metal is used in many ways. The first symptoms usually appear a few hours after being in contact with nickel.
Skin is a living organ that reacts to what can harm you. In cases of not too severe food allergies, skin is usually the first organ to react, creating rashes and redness.
Tattoos are very fashionable and whether it is a large piece or a tiny butterfly on the wrist, ink and needles are always required to pierce through the skin and stick the ink in your flesh. But do you know why tattoos fade? As mentioned above, skin is a living organ and a tattoo on your skin will never be as a drawing on paper. Skin evolves and moves and the designs follow the evolution of its support. Tattoo ink contains metal that is identified by your body as a foreign object. It is therefore the same process than it is for a virus or any bacteria. Of course, the work of white blood cells is not as intense as if it was a proper disease trying to spread but they will slowly attack the ink, breaking it into different molecules, easier for your body to digest, literally. The immune system identifies the ink that has been punched through the epidermis as an enemy and by breaking the composition of the ink, sends the broken molecules to your kidneys and liver that will eventually evacuate it through the natural ways, while going to the bathroom.
This phenomenon is why you have to get your tattoos touched up after a few years and why the lines are not remaining as sharp as on a piece of paper.
