<p>Henna is a dye that is commonly used to stain the skin orange. Originating from the middle-east these tattoos are becoming increasingly popular. To make the tattoos look more like 'real' tattoo's a chemical called Para-phenylenediamine (PPD) is used to create 'black henna'. No needle is used with this kind of tattooing however the PPD has been known to cause skin reactions in some people.  This image shows such a reaction on an arm tattoo, classic signs of blistering can be seen, this can be at the site of the tattoo as shown here or elsewhere on the skin and it may resolve without clinical intervention. The blisters may leave scarring or sometimes affect skin pigmentation. Photograph 06/10/2014</p>
