I must say, Karren Brady is looking sensational - far younger than her 56 years. She's changed her hairstyle, lost a lot of weight, tightened up her jawline...
But what we're all really fixated by are her arms - slim, toned, youthful - which she credits to sessions of a special skin toning and reconditioning treatment at the Dr Rita Rakus clinic in London.
As an expert, who has had hundreds of tweakments, I know all about the treatment Karren had - and the others she could've chosen.
So, if you're disenchanted with your bingo wings and determined to tighten them up by Christmas, read on for my top five arm tweakments - and the instant way you can fake toned triceps for free...

Tone up arm muscles
Exion, which is what Karren had, is a decent treatment for helping skin quality and firmness, but I'd suggest working on your arm muscles first.
Get going with press-ups, bicep curls and tricep dips, and you can supercharge your muscle-toning in clinics with treatments such as EmSculpt Neo which uses high-intensity electro-magnetic frequencies to tone and build muscles while radiofrequency zaps fat beneath the skin.
I've only tried one session on my triceps but they were popping afterwards! (Find a practitioner in your area via btlaesthetics.com/uk/find-a-physician, from £300 per session depending on location).
Mild microneedling
'Arms are probably my most requested concern,' says body-contouring specialist Dr Galyna Selezneva, 'both the so-called bingo wing but also skin quality and texture.'
First, she'll tone your arm muscles with Deleo Cristal Fit (£300 per session) which works just like EmSculpt Neo, then to give skin texture a makeover she moves to radio-frequency microneedling with Sylfirm X (from £1,200, drgalyna.com).
'With Sylfirm X I can "cover" the arm, armpit, inner and outer elbow area, forearm and hands in one treatment. There is little downtime and virtually no pain.'
This is the preferred approach of her patients in London's Knightsbridge, says Dr Selezneva.
Jabs for crepey skin
One arm tweak I've tried with success is Profhilo Body (£1,500 for two sessions, drpreema.com). This means injections of the same hydrating, skin-reconditioning product that's popular for face treatments. A month after my second round of treatment, the crepey bits on my inner arms were magically tauter and smoother.
Some practitioners mix Profhilo with other skin-conditioning injectables like polynucleotides and PRP.
Dr Sach Mohan injects it into just-lasered skin, to banish crepey skin. Expensive, sure, but his celebrity patients are queuing up for it (from £1,400, revereclinics.com).
Laser tightening

Not for the faint-hearted but hugely effective. 'Laser coring' with the Ultraclear laser involves drilling out thousands of tiny 'cores' of skin - which then shrinks as it heals. 'We make holes large enough that when the edges close up they tighten the skin, but not so large that they leave a mark,' says Dr Raj Thethi, a leading aesthetic practitioner in Leeds who uses Ultraclear on saggy body skin as well as the face.
'We can shrink the skin area by five or six per cent, permanently, in a single session.' The treated area will take a week or two to heal, but then you'll be flaunting sleeveless tops (from £3,000 for both arms, yorkshireskincentre.co.uk).
Non-surgical fat melt
Endolift (around £3,000, drpriyaverma.com) uses a tiny laser, slipped beneath the skin and into the fat on a super-fine optic fibre, to sculpt and melt fat. The more invasive BodyTite (around £3,500, widely available) uses radiofrequency energy on a probe under the skin to melt fat, which is sucked out while the heat from the radiofrequency boosts collagen production in the skin.
Thin arms in photos
Learn to stretch your little fingers. Try this in front of a mirror so you can see the difference.
Hold your arm out to the side and relax your muscles. Reach your fingers out away from you. Now concentrate on pointing the little finger and see the way this instantly tenses up the 'swing' of the bingo wing.
OK, so it only works while you’re holding your arms out to the sides, but it’s a good one to have up your sleeve. As it were.
