The British Skin Foundation is issuing a warning this summer over so-called “black henna” temporary tattoos (BHTTs) after research among dermatologists reveals they are seeing an increase in reactions at their clinics.
Parents hoping to treat their children to a temporary tattoo on holiday or at the funfair, along with party-goers at festivals may not realise the dangers of BHTT.
The majority of BHTT are not based on henna at all, but a substance called para-phenylenediamine (PPD) which is found in hair dyes. PPD is allowed for use in hair dye, but its use for skin contact products such as temporary tattoos is illegal in the European Union.
When PPD is used on the skin in this way it can cause blistering, painful skin burns and may even lead to scarring. It can also leave the person with a lifelong sensitivity to PPD, which increases the risk of a severe allergic reaction when using hair dye in the future.
Our survey found:
•Four out of 10 dermatologists asked had seen patients with skin reactions to BHTTs.
•One in 20 dermatologists approached said that over 80% of the BHTT reactions they had seen were in children aged under 16.
•Dermatologists asked confirmed that around half of the patients got a BHTT outside of the EU, where the legal status of PPD is not always clear; however the other half got a BHTT within the EU, with 27% of these in the UK.
•About two-thirds of dermatologists approached have seen an increase in patients with reactions to hair dyes, many of whom have previously had a BHTT.
Dr Anjali Mahto, consultant dermatologist andBritish Skin Foundation spoksman, said: “Black henna is well known to cause skin reactions and should be treated with caution, particularly in children.”
The decision to issue this warning is backed by the Cosmetic, Toiletry & Perfumery Association (CTPA).
“The message is clear: having a ‘black henna’ temporary tattoo presents a significant risk of a very nasty adverse reaction to the tattoo itself.
“It also increases the risk of either not being able to use most hair dyes in the future or having a bad reaction to them if the warnings are ignored. This summer, parents will want to keep their children safe, by steering clear of so-called ‘black henna’ temporary tattoos.”
The British Skin Foundation survey was undertaken at the British Association of Dermatologists’ Annual Meeting between this July in Manchester.
Only dermatologists were invited to take part and were identified by their delegate badge.
In total 244 completed the survey, of which 56 were male and 188 female.
The survey included questions from the British Skin Foundation, other companies as well as the CTPA.
It was blind, unbranded (due to it being run on the British Skin Foundation stand) and respondents received no financial reward.
