The energy density (fluence), expressed as joules/cm2, is determined prior to each treatment as well as the spot size and repetition rate (hertz). To mitigate pain the preferred method is simply to cool the area before and during treatment with a medical-grade chiller/cooler and to use a topical anesthetic. During the treatment process, the laser beam passes through the skin, targeting the ink resting in a liquid state within. While it is possible to see immediate results, in most cases the fading occurs gradually over the 7–8 week healing period between treatments.
A simple, new technique (published in March 2014) which helps to reduce the pain sensation felt by patients has been described by MJ Murphy He used a standard microscope glass slide pressed against the tattooed skin and fired the laser through the glass. Results on 31 volunteers showed a significant reduction of up to 50% in pain alongside a reduction in blistering and punctate bleeding. This technique represents the simplest and most effective method to reduce the pain sensation using a non-invasive procedure.
The usual design is comparable to a full-sleeved garment sold by many clothing companies. Why is it so? Well, it is simply because it covers the entire arm parts of the person most of the time. The tattoo design can possibly be a single design that extends from the shoulder up to the wrist part, or a group of smaller gorgeous designs that connect to one another until they reach the wrist part. This has caused the existence of half sleeve design, which only covers half of the person’s arms. These tattoos usually start from the shoulder up to the elbow. However, there are cases that the tattoo starts from the elbow up to the wrist part.
Not everyone is an ideal candidate for laser removal. “Removal is always going to be more difficult in patients who have a darker skin tone based on laser physics and the way the laser works,” says Susan Bard, M.D., a board-certified dermatologist and a fellow of the American College of Mohs Surgery. “The laser targets pigment that’s in the dye, but at the same time, it can also target melanin in your skin. So, the darker your skin, the more complicated it will be to utilize a laser to remove the tattoo.” Laser removal can cause burns and hyperpigmentation in darker skin tones.
A poll conducted in January 2012 by Harris Interactive reported that 1 in 7 (14%) of the 21% of American adults who have a tattoo regret getting one. The poll didn't report the reasons for these regrets, but a poll that was done 4 years prior reported that the most common reasons were "too young when I got the tattoo" (20%), "it's permanent" and "I'm marked for life" (19%), and "I just don't like it" (18%). An earlier poll showed that 19% of Britons with tattoos suffered regret, as did 11% of Italians with tattoos.
Another common smaller tattoo for people to get is a simple letter. The letter P may symbolise the persons first name, someone’s name that’s important to them or even the periodic symbol for Phosphorus. There are thousands of fonts to choose from and luckily with letters it’s easy to test them out on your computer before you pick which one will look best.
