Carbon dioxide is being touted as the next big thing for facial treatments, and it involves the odourless gas (which makes up the air we breathe as well as being blamed for heating up the planet, hmmm) being injected into the skin as a rejuvenating treatment.

The "fizzy facelift", as it is being dubbed, is supposed to tighten and brighten the skin, although skin specialists are in two minds about the new procedure.

Daniel Sister, a cosmetic doctor in Notting Hill, London, says, "Carboxytherapy works. It won't get rid of deep wrinkles, but it does create brighter, good-quality skin."

Dermatologist Jeanette Graf however, has a warning for potential fizzy-faced fans. "Injecting CO2 - particularly around the eyes, where it can potentially release gas bubbles into blood vessels in the eyes – can cause blindness," she said. "It is not clinically tested."

At around $200 a pop (you will need at least six for noticeable results), the fizzy facelift really is like a glass of champers. It will give you a lift and make you feel bubbly for a while, but the hangover effects will certainly be felt in your purse.
