The dermis, the target for your tattoo ink, is located between 1 mm and 2 mm beneath the skin's surface. 1 mm is equivalent to 0.03 inch. The precise depth varies from person to person, but 1 mm is the lowest and 2 mm is the highest. All of your work must take place within this time frame. If you go any deeper with your tattooing or cover up some old tattoos, you risk seeing them reappear later in more vivid color.
The thicker your subject, the deeper it will go. A human head can be tatted up to three-quarters of an inch deep.
Ink colors come in various degrees of darkness. Black is considered the darkest color, while gray is next in line and white is the lightest. However, all colors can be made by mixing different amounts of black with other colors. For example, red can be made by mixing equal parts black and white; orange is half black and half white; yellow contains a high amount of white; green has more black than white; blue uses almost exclusively white; violet is nearly all black.
So, one could say that tattooing is a form of painting, except that black paint is mixed to create every color. Tattooing also involves staining the skin through the use of chemicals which change the color of tissue just like pigment would on canvas. Finally, tattooing is done by making incisions into the skin and filling them with ink.
As a result, the dermis layer is about 1/16th of an inch deep in the skin. With this information, the tattoo needle's tip is modified to only pierce the skin at a specific depth, not a millimeter shallower or deeper. This implies that the tattoo needle should not protrude more than 2 mm or less than 1 mm from the tattoo machine.
The ideal tattoo needle has a sharp point for making small, controlled strokes when drawing up ink droplets and a wide base to hold the ink cartridge open. The length of the needle should be such that it can be used with confidence by any artist working in a standard size studio. Tattoo needles are available in different sizes from fine to broad. The most commonly used sizes are 0, 01, 02, 04, and 06. The smaller the number, the finer the point and the more flexible the needle will be. The larger the number, the coarser the point and the more rigid the needle will be.
Tattoo needles are usually made of stainless steel or titanium. They can be single- or double-pointed. Double-pointed needles allow you to work with greater precision because you can separate each drop of ink with greater ease. They are generally more expensive than single-pointed needles. Stainless steel needles are popular because they are durable and easy to clean. Titanium needles are lighter than stainless steel ones and their price tends to be higher as well. They are also more difficult to clean because they tend to tarnish when exposed to air.
If you go too deep, you will be inflicting additional discomfort to your client and risking infection. The dermis layer of skin is 1 to 2 mm thick. As a result, while adjusting the tattoo machine, you must also modify within this parameter. A good rule of thumb is that you should not go deeper than this thickness into the skin.
The other factor that affects needle depth is concentration. If you are not concentrating enough on what you are doing, you risk pushing the needle through to the other side of the skin layer rather than just into the fat tissue below. This would cause pain for your client and might even expose the bone underneath the skin layer.
In general, you should try to keep the needle's depth no greater than 3-4 mm. Any more than this and you are in danger of injuring the muscle or bone beneath the skin layer.
Also worth mentioning is that different people have fat tissues at different depths. So if you are new to tattooing, it is best to start with shallow tattoos and work your way up as you gain experience.
Tattooing penetrates 1/16th of an inch into your skin, passing through five layers of the epidermis. The dermal layer is the dermis's topmost layer. It provides strength and elasticity to the skin. The subcutaneous layer lies next to it. This is where blood vessels and nerves run along with muscle fibers and tendons. Beneath this is the hypodermis, which is the deepest layer of the skin. This is where fat cells are located.
The average person has about 100 million fat cells. They store energy when you are not using it and release it when you need it. This is why you can't eat too much food - it will be stored as fat if there is room in your fat cells. Men have more fat cells than women because they need more energy. Children have many more fat cells than adults do because their bodies are growing all the time so they need more energy stores to fuel that growth.
Fat cells don't just grow up overnight. Scientists still don't know exactly how some people gain weight faster than others - it may be due to various genetic factors or maybe it has something to do with eating different types of foods. Whatever the case may be, once you start storing fat cell it becomes easier for you to add more fat cells later in life.
