Removing tattoos is painful and expensive. What's more, tattoos don't always come off. Attempts to remove them may result in scarring, skin thickening, discoloration, or other problems. Be sure you're not allergic to any tattoo inks or dyes. If you are, your body could react adversely to them.
Many states prohibit the tattooing of minors.
There are no standard guidelines governing tattoo-parlor safety and sanitation. You cannot donate blood for a year after getting a tattoo. Know what you're getting into. Talk to others. What you put on your body now may not be the message you want to send to a loved one five years from now or to your future child.
