Adverts from six companies selling liquid Brazilian butt lifts (BBLs) have been banned in the UK for trivialising the risks and exploiting women's insecurities around body image.
All of them appeared on Facebook or Instagram and used time-limited deals to "irresponsibly pressurise" customers into booking, says the Advertising Standards Authority (ASA).
One ad, for example, tried to entice customers with an "exclusive opportunity" to get a "perfect peachy look".
Liquid BBLs involve injecting filler into the buttocks to lift them and make them look bigger or rounded.
