Here's Why Tattoos Get Blown Out
Daniel Cobb
And contrary to what you might think, a blowout isn't always the artist's fault. Blame can also be attributed to the client, especially if they've moved around during the session either through nerves, fidgeting, or twitching (via Demi Love).
Blowouts can also be a result of incorrect placement, as the skin isn't the same thickness all over the body and everyone's skin is different. Blowouts tend to occur more frequently on parts of the body with thinner skin, including wrists, hands, ankles, and the inner parts of your elbow and knees. And if an artist needs to stretch and tighten the skin more in these areas, skin pulled too tightly can lead to a blowout due to the angle of the needle (via Authority Tattoo).
Unfortunately, there's not much you can do with a major blowout. However, if it's viable you can get it covered up with another tattoo (via Healthline), or even remove the blown out portions with laser removal. In a worst-case scenario, you can have the entire tattoo surgically removed, but this can cause major scarring as a surgeon will have to cut the tattoo from the dermis and stitch the remaining skin back together.
