BTL Unison™

Cellulite Reduction: BTL Unison™


A device-led cellulite treatment, Unison simultaneously treats the five causes of cellulite in a safe and effective way.

Areas treated:

  •  Buttocks
  • Front of thighs
  • Back of thighs
  • Abdomen
  • Flanks

How does BTL UNISON™ work?

UNISON employs the clinically-proven technologies of radio frequency (RF) and targeted pressure energy in a hand-held, clinic device. Both these technologies are proven to increase the production of collagen, which increases the skin’s elasticity. With a controlled temperature application, the amount of fatty deposits in any affected area are reduced. The pressure on the connective strands means that the fibrous structures relax and reduce the underlying tension in the skin, which create that dimpled effect.

How do I know I am suitable for BTL UNISON™?

If you have visible areas of cellulite and are fit and healthy, then the chances are that you will be able to undergo a treatment of BTL UNISON™. However, prior to any treatment here at Dr Preema London, we will invite you to attend a no obligation consultation, so we can ascertain your individual concerns and advise on the most appropriate treatment plan for you.

How long does a BTL UNISON™ treatment last?

The heat and shock waves need to be applied to the cellulite-affected area for around 10 minutes each area, therefore, depending on the number of areas to be treated, the process can last between 10 and 60 minutes.

Does a treatment with BTL UNISON™ hurt?

BTL UNSION™ is a completely painless, safe and effective treatment, feeling rather like a hot stone massage with vibrations. As it is a non-surgical procedure there is no need for anaesthetic or an overnight stay in hospital. You can return to your daily activities immediately after your treatment, with very little side-effects apart from some tenderness and slight swelling, which will subside in a day or so.

When will I see results?

In some cases, results can be seen after one session and will continue to improve over the coming weeks, following your treatment course. On average, around 6 sessions will be required to produce long-term results. Your practitioner will discuss with you how to maintain your results with a good diet and healthy exercise regime.

Will BTL UNISON™ work on men?

Although women are more likely to develop cellulite, men are definitely not immune to the condition and we have seen some superb results on our male patients. The treatment will work in exactly the same way for both men and women and for any skin type.
