We know that tattoos are quite fashionable and more and more people are deciding to get their skin adorned with them. But the world of tattoos still raises many questions — most of them being myths. There are many people out there wondering if just anyone can get tattoed or if they fade over time. Some people even think that there are colors that hurt more when getting inked than others.

Enlighten decided to carry out some research online to know more about these common tattoo myths and we found out that most of the time, they’re just that — myths. So we debunked a few of them and found out the reasoning behind the ones that turned out to be true!

1. You can’t donate blood if you have a tattoo.

You’ve probably heard multiple times that people who have tattoos can’t donate blood at all. Of course, that’s nothing but a myth, or at least, it’s not entirely true. They can donate blood if they meet all the requirements to become a donor.

Since tattoos are made using a needle that goes all the way to the dermis (a deep layer of skin), if it’s not done properly, it can lead to blood infections. However, once a period of time to rule out a blood infection has passed (which could last at least 6 months after the tattoo was first done, but it all depends on the country and the medical institution in question), the person can then donate blood.

2. You shouldn’t get a tattoo if you’re pregnant.

There’s very little evidence, so far, proving that pregnant women put their health or their baby’s health at risk by getting a tattoo. At least, there’s no additional risk associated with getting a tattoo while pregnant. Just like non-pregnant women, future moms have to deal with the risk of blood infections due to a lack of hygiene at certain tattoo shops or poor skills.

If you decide to go and get a tattoo while pregnant, keep in mind that some doctors recommend not getting a tattoo on your back, because they think it could interfere with a potential epidural shot. Often, the needle is inserted outside of the tattooed area to avoid mixing it with the pigment.

3. People with diabetes can’t get a tattoo.

This one’s a total misunderstanding. Let’s debunk this myth! Having diabetes is no reason not to get a tattoo. The only thing that’s currently suggested by doctors is to avoid getting tattoos on the areas of the body where less blood circulates and where you usually inject insulin. That’s simply because you could hurt your skin.

But take note of the following information. The above recommendations are directed to patients who take good care of themselves. For those who have ignored their doctor’s advice or whose diabetes is completely out of hand, then yes, they could be at risk. Their skin could’ve lost some of its healing capacity or they might have a weaker immune response to infection.

4. Getting a tattoo hurts more or less depending on the place you get it.

It’s true, the pain you can feel from a tattoo depends not only on how well you can stand pain in general but also on the location of your tattoo. Usually, tattoos that hurt the most are those located in a place with very little fat. That includes, of course, any skin near a bone, or in places on your body where there are more nerve endings. If you’re concerned about this, be sure to avoid getting tattoos on your armpits, ribs, ankles, breasts, elbows, hips, neck, or face, among others.

5. People with tattoos can’t get MRIs.

The belief that a person with a tattoo can have problems getting an MRI spread because of the metallic components found in tattoo ink. But this is definitely a myth: according to a study carried out by the Max Planck Institute in Germany, the possibility of side effects are so small, it’s close to negligible. In fact, the study mentions this merely as a small number of isolated cases rather than a general rule for tattooed people.

6. White tattoos are more painful to get than others.

This idea is completely false. Normally, when you get a tattoo, the tattoo artist saves white for the end, just to make everything a bit brighter and adjust some minor details. But by this time, your skin is most likely already pretty sore from getting ink injected into your dermis for several hours. It’s hardly surprising that you’d feel more pain at that point. But this has nothing to do with the color of the ink — it just happens because your skin is already very sensitive.

7. Black ink turns blue or green with time.
