It is possible for skin to reject ink but it is very uncommon. You should always use a legitimate artist in an established business. This will make you feel more at ease and be safer for you body in general.
If you feel that you are having an allergic reaction to the ink contact the artist who did your body work and your doctor immediately.
The artist should be able to supply you with the name of the ink they used and/or a list of ingredients in the ink used that will help you and your doctor figure out why your body is reacting the way it is.
If your tattoo artist went below or above your dermis the ink will not hold correctly or will fade easily. The more you bleed the lower in your dermis the tattoo was imprinted. The fatty cells there do not hold the ink as well and will cause a faded look.
Most fade outs on tattoos are a result of the healing process.
Most people notice the fading with red or white ink, although any color may fade. The healing process (scabbing) can push the ink up out of the skin and cause a splotchy look.
Remember that new tattoos need to be kept cleaned and moisturized. Never pick the scabs of your tattoo.
Caring for Your Tattoo
The better you take care of your new tattoo today the better it will look tomorrow and in the future.
Initially, the skin around your tattoo will be a bit swollen. Monitor your skin for pain, redness that spreads outward from the tattooed area, excessive swelling, or pus. Contact your physician if any of these occur.
Your tattoo is really is a series of puncture wounds that have been filled with ink. Treat it as you would any other wound. You should keep a bandage on the tattooed area at least a day.
Make sure you wash the area with antimicrobial soap such as Dial. You don't want to use alcohol as a cleaning agent. Alcohol will dry out your skin, can cause cracking, and both of those conditions can result in additional scabbing and loss of ink.
After washing pat the skin dry with a soft tissue.
Do not rub.
You can gently smooth over an antibacterial or antibiotic cream onto the tattoo. Most Artist will recommend any drug store counter ointment. There have been ointments made especially for tattoo care such as Tattoo Goo and Nu Tattoo Aftercare Products. Give your skin time to heal and don't expose it to pool water, or even hot bath water. Sunscreen is never a bad idea for your skin and body art.
Most artist provide free touch ups on their art. Others will touch up their work for a small fee. Get your tattoo touched up after you've completely healed. The skin will be scarred tissue from the initial tattoo and will hold the ink better.
If you've experienced this on more than one tattoo this will be indicative of your healing process. I highly recommend using an artist who will provide free touch ups on his work and performs his art in a licensed tattoo studio.
