Allergic reactions to tattoo inks are very uncommon but usually an allergic reaction would show up with a shade of red ink. Red ink is the only color that no current tattoo ink manufacturer has developed to be hypo-allergenic. Ink makers have the either most of or the rest of their colors hypo-allergenic, so you only need to worry about red if you have allergies to certain pigments.
People who are allergic or sensitive to certain metals may react to inks in the skin by becoming swollen and/or itchy, oozing of clear sebum is also common. People with allergies should think carefully about getting a tattoo because of the risk of anaphylactic shock which can be life threatening.
Unfortunately when a person gets a tattoo there is always the potential to develop an allergic reaction to the tattoo ink. While allergic reactions are rare, they do happen. This is a result of the different types of materials that make up the composition of the tattoo ink.
The usual signs of an allergic reaction can range from localized redness to a generalized eczema-like rash. Steroids are usually used for treatment but keep in mind that just because a tattoo is red and irritated it does not mean that you are having an allergic reaction to the tattoo ink.
Tattoo allergies can also cause the formation of hives, which can usually be treated with medication at home. very rarely tattoo ink allergies can develop complications that are more serious. when this happens it is possible to experience difficulty breathing, wheezing, and swelling in the throat area and more.
It is always a good idea to keep an eye out for any signs of an allergic reaction to the tattoo ink anytime that you get a tattoo. Basically always follow the overall directions too about keeping your tattoo clean and keeping it away from exposure to sunlight and moisturize the area at least once a day.
There are many metals that are put into tattoo inks, including nickel, which is said to be the most common metal allergy. most normal earrings are made from nickel, so if you can wear those, some tattoo inks may not be able to be used. if you have allergies to metals then speak to your tattoo artist prior to actually getting the tattoo so you can discuss options.
Tattoo ink is made of two basic components; pigments and carriers. Pigments are pretty much anything that can be finely ground down to provide color. Minerals, vegetable dyes, plastics, and metallic salts are all substances that have been used to create tattoo inks. Tattoo inks can result in some really great body art, but you need to do what you can to protect yourself.
Manufacturers of tattoo ink do not have to divulge what is in it, so you, and likely your tattoo artist, may never know exactly what chemical compounds have been used. if you have allergic reactions then you should be extra precautions when getting a tattoo to ensure that you do not have an allergic reaction to the tattoo ink.
