Alec Falkenham doesn’t regret any of his tattoos. But, if he did, he’d know how to remove them, or at least fade them, without going through the torture of laser or spending a fortune. This Canadian student has patented a cream that takes advantage of the immune response to pigments in inks to remove records of failed love or reminiscences of youth from the skin.
When ink is injected into the skin the body reacts by sending cells called macrophages to the area to absorb the pigments into the lymphatic system and so clean up the area. However, some of the cells that have "eaten" the pigment remain in a deeper layer of the skin, which explains why tattoos are visible. Read More
Getting a henna tattoo is an engaging experience for adults and children in the summer. After all, it is just for a few days. But you may end up regretting it. Tattoos made with black henna, whose decorative motifs may even include glitter, can trigger severe allergic skin reactions and permanent sensitization.
Henna is traditionally used in North Africa and other parts of Asia as a hair dye and in religious and ritual tattoos. This natural henna is dark green to brown in colour and lasts three or four days at most. But black henna can draw on the skin in a way more like the ink used in permanent tattoos because, as the name suggests, it is darker in colour. Its success on beaches, especially among children, is explained by the fact that it lasts longer and is easier to apply. To achieve this effect, various colours are added to the natural henna – which is where the problem lies, as they include paraphenylenediamine (PPD). Read More
Part of the fascination of tattoos is that they leave an indelible mark on the skin. Beyond any artistic or literary value, there is something profound about the fact that they are "forever". But the reality is that a third of people eventually come to regret their tattoos.
This is the main conclusion of a study conducted in England and presented at the last meeting of the American Academy of Dermatology. The study also reported that twice as many men as women regret their tattoos – three times as many if they were tattooed as boys (before the age of 16). Interestingly, almost half the respondents (men and women both) had more than two tattoos and 31% had more than five. It all seems logical: in recent decades the fashion for tattooing has seen spectacular growth, with a mushrooming of tattoo parlours in the first world. Many people get a tattoo simply because it is fashionable – and do not dwell too much on the long-term implications. And that they are long-term goes without saying ... Read More
A few years ago laser was the stuff of science fiction. Nowadays it is present in our lives ... and in our skins. Dozens of laser devices are available for aesthetic applications, such as permanent hair removal. But these techniques are not without risk, most especially when non-experts use these devices.
Manufacturers worldwide have sold thousands of lasers for dermatological applications, whether aesthetic or surgical. But many aspects regarding their use remain unregulated. For example, it has not been clarified whether or not laser hair removal is a medical treatment. If it were medical, only specialist doctors could perform this task. A report has come to light in the USA warning of the growing number of lawsuits regarding damage caused by lasers operated by non-qualified persons, especially outside traditional medical settings.
