Temporary tattoos may not be as harmless as people think, new study finds.
Non-permanent body art has become popular amongst young people who want to decorate parts of their bodies with no lasting effect but now a study has found that ‘black henna’ tattoos may have bad side effects.
Permanent tattoos are injected into the skin but temporary tattoos marketed as "henna" are applied to the skin's surface.
According to a report on fda.gov, some of the temporary tattoos, which normally last from three days to several weeks, contain hair dye including p-phenylenediamine, or PPD; a product that can cause allergic reactions in some people.
Some of the side effects include redness, blisters, oozing lesions, increased sensitivity to sunlight and permanent scarring.
"Just because a tattoo is temporary it doesn't mean that it is risk free," Linda Katz, M.D., M.P.H., director of FDA's Office of Cosmetics and Colours was quoted saying.
Difference between traditional henna and black henna
Traditional henna (Mehndi) which is usually reddish brown in colour is made from a dried henna plant which is ground into a paste to make a dye.
Black henna is a mixture of henna along with other ingredients or may really be hair dye alone, according to the FDA.
