From plunging your face into bowls of ice water to rolling frozen tools across your cheeks, social media is full of quick fixes promising to depuff your face in minutes.

While these techniques look convincing on screen, dermatologists say many of them are misunderstood, overhyped and at best, temporary.

Consultant dermatologist Dr Aiza Jamil says facial puffiness is usually caused by fluid retention and common triggers include high salt and alcohol intake, allergies and lack of sleep.

Dr Tina Tian, also a consultant dermatologist explains most viral hacks fall into three categories - cold exposure, massage and temporary tightening effects.

They can "genuinely reduce visible swelling and provide relief but the key word is temporary - they won't permanently change facial structure".
