Charity Pulmonary Hypertension Association UK (PHA-UK) aims to encourage over 40,000 people to provide a blue lipstick print of their lips to set a new Guinness World Record.
Research shows that lack of awareness of PH can delay a correct diagnosis by up to three years.
The campaign, called 'Pucker Up 4 PH', urges anyone who lives with unexplained breathlessness to visit their family doctor. It is estimated that there are over two million people living with undiagnosed COPD.
PHA-UK’s Paul Pennington said: ‘Blue lips or cyanosis, as it’s medically termed, can indicate the presence of a number of conditions including PH.’
Participants donating lipstick prints so far include the cast and crew of the West End shows Wicked and The Lion King.
