Not getting a tattoo and body piercing infection is the first lesson you should learn.
Body piercing involves invading the epidermis and dermis layers of our skin, therefore is has a higher risk of getting an infection. Because of this, more care is required to avoid an infection. A well maintained washed area and the use of the cream should be included by your professional piercer or tattoo artist.
Body piercings tend to get infected if they are botched. So make sure you go to a reputable piercer who can provide you with sterile needles and materials. This is the number one preventative step you can take.
On the other hand, tattooing is less like to get infected because of the way tattoos are done. The tattoo ink is only introduced in to the dermis layer of the skin. It is normal that bleeding will occur, but tattooing is done using shallow needles and thus has a low risk of getting an infection.
Be sure that your tattoo artist has a very good reputation and uses sanitized equipment. A number of experienced artists possess an autoclave to sterilize their equipment. The major risk of infection with tattooing is hepatitis C caused by using a dirty needle.
A few of the signs of infection are inflammation, cloudy seepage, greenish scabbing, redness and tenderness. There might be signs of an allergic reaction like swelling, redness and itching on the infected area. You must tell your piercer or tattoo artist to any allergies to any products even sensitivity to inks.
Even if most piercing and tattoos are painful, the pain usually subsides after a few couple of days to a week. If your tattoo does not show any sign of healing, you should inform your piercer or tattooist and have them looked at it. In most cases like this they know what you tell you, need to do to cure the minor infection.
Lastly, if you get an infection that is not a normal skin irritation you must get help of a physician. You may need to take antibiotics to get rid your body of the infection. Many times this can be cured without losing the piercing and without damaging your tattoo.
