Doctors have long been aware of the regenerative abilities of fat. Packed with stem cells, fat holds the potential to stimulate collagen, improve elasticity and even help slow signs of skin ageing.

But its greatest asset is that it is entirely natural. These days, we’re all paying a lot more attention to what we put into our bodies, and when it comes to an ‘organic’ form of rejuvenation, fat seems to tick all the boxes.

Touted as the next generation of nano-fat, Uvence is the brainchild of Dr Olivier Amar, a consultant plastic surgeon based at London’s Cadogan Clinic, whose father was one of the pioneers of fat transfer. ‘It’s emulsified fat,’ Dr Amar says of the end product, which can be injected with a cannula, similar to a dermal filler. ‘We have calibrated the fat cells, so there is no capacity for volumisation.’ (A relief for those worried about looking puffy or over-filled.) ‘Instead, these adipose-derived mesenchymal stem cells regenerate the skin. Think of it as an alternative to Profhilo [a hyaluronic acid-based skin booster], but more natural.’
