ModBlog News of the Week: April 29th, 2011
By Rob • Apr 29th, 2011 • Category: ModBlogWith all the attention in the news this week focused on the royal wedding, there weren’t a lot of stories for this week’s news. This meant I actually had to dig up a couple of celebrity stories just so the week wasn’t completely devoid of content.
To kick things off this week we’re going to start with a little science. A researcher in London has developed a formula that will predict the rate at which a tattoo will fade over time.
Tattoo inks are a suspension of water-insoluble particles, such as mercury, lead, cadmium and iron, which are injected under the skin using a needle. Over time, these inks become dispersed as the cells which contain them die, divide or leave the body.
Although modern tattooing inks are less likely to fade, their gradual deterioration is inevitable. Dr Eames said: ‘Skin type, age, size, exposure to the sunlight and the type of ink which is used all influence how a tattoo disperses with time. ‘Broadly speaking, the small details in a tattoo are lost first, with thicker lines being less affected. ‘Although finely detailed tattoos might look good when they are first done, they tend to lose their definition after 15 years.’ He added that his model will help increasing numbers of young people who have gone under the tattooist’s needle. ‘Tattoos are incredibly popular worldwide with more than a third of 18 to 25-year-olds in the U.S. sporting at least one design,’ he said. The research is published in the Mathematics Today journal.
I wonder if his model takes into account sun exposure, as well as the fact that not everyone’s skin is the same. I guess only time will tell. What I don’t get is how this will assist people when it comes to getting a tattoo. It’s not like it isn’t common knowledge that tattoos can fade over time.
