The Advertising Standards Authority has banned recent 'Proactive' skincare commercials featuring a number of stars, most notably Katy Perry and Justin Bieber.
The US singers have also been removed from Proactive's website, with only Made in Chelsea 'Star' Gabriella Ellis remaining to advertise the acne cream.
The Advertising Standards Authority made the move to ban the advert after there were complaints that it was misleading as the American celebrities were advertising a product containing different ingredients to the one available in the UK.
Katy Perry seems to have been involved in a few bans recently. Click here to find out why she was banned from wearing spinning bras... And scroll down to watch one of the Katy Perry Proactive adverts.
