Our London Thermage FLX treatments offer a quick, single-session solution for tighter, more youthful skin with minimal downtime. Combine it seamlessly with injectables for instant enhancements.
Thermage FLX with Ultherapy are the leading non-invasive face/body lift treatments globally, working together to tighten sagging skin and enhance volume for natural, long-lasting results. FDA and EU CE approved for skin tightening.
Thermage skin tightening treatment is a system which targets the deeper layers of skin without touching the top layers resulting in a totally non-invasive treatment with the top layers being constantly cooled by cryogen blasts.
The result is that whilst new collagen and elastin are produced over a period of up to 6 months, there is no initial downtime, just a slightly flushed face and a little patience needed until the often remarkable effects can be seen.
It truly is a great treatment, and a favourites of many celebrities.
I decided to do something about my post-partum stomach, but I didn’t want (or perhaps need) any invasive treatment so was delighted when I found out that Thermage could help! Highly recommended, and it provided great results for the summer.

Thermage FLX treatment is the world’s leading non-surgical skin tightening and sculpting treatment with over 2.5 million worldwide treatments and 18 plus years of innovation!
It works using radiofrequency technology to heat the deeper, collagen-rich layers of skin causing collagen to contract and encourage new collagen rich layers and elastin to grow. Most importantly, Thermage FLX won the best new technology award in 2017 from the Aesthetic Industry Awards.
What makes Thermage FLX treatment differ from other radiofrequency providers is how it simultaneously treats and delivers cryogen blasts both cooling and protecting the epidermis resulting in a comfortable and non-invasive experience.
Thermage is undoubtedly the industry Gold Standard for radiofrequency treatments and has been used by many famous people such as Jennifer Aniston and Gwyneth Paltrow for an overall younger looking appearance.
Thermage treatments improve over time and can last for over a year with optimal results becoming apparent after around 4 months.
Thermage FLX pricing depends on the treatment area and number of pulses required. At Retriva, treatment prices typically range from £825 for smaller areas to around £5,000 for larger body treatments. A consultation will help determine the most suitable treatment plan and cost.

Lines around the mouth, eyes, and forehead
Lack of definition of the jawline and under the chin

We focus on natural-looking results, patient safety and evidence-based treatments using the latest Thermage FLX technology.

The great benefit if Thermage FLX is that generally only one treatment a year is required to maintain optimal collagen production banking and visual benefits.
Most patients tolerate Thermage FLX well. During treatment, you will feel a brief heating sensation followed by a cooling effect designed to protect the skin and maximise comfort. Sensation levels vary between individuals and treatment areas.
Thermage FLX is one of the safest non-invasive skin tightening and sculpting treatments available and is endorsed by both the US Food and Drugs Administration (FDA) and EU CE. In addition, there have been over 50 clinical studies and over 2.5 million treatments worldwide.
One of the key benefits of Thermage FLX is that there is little to no downtime. Most patients can return to their normal daily activities immediately after treatment.
Most people are suitable for treatment but the key demographic would be those aged between 30 and 60. However, this can be flexible, especially for those with naturally good skin quality. Contraindications would include those who have a cardiac pacemaker or other active implants, certain skin conditions and who have recently had fillers.
Thermage FLX, HIFU and Ultherapy are all non-surgical skin tightening treatments, but they work in different ways. Thermage FLX uses radiofrequency energy to stimulate collagen production throughout the skin, while Ultherapy and HIFU use focused ultrasound energy to target deeper tissue layers. Thermage FLX is often chosen for overall skin tightening, skin quality improvement and collagen stimulation across the face and body. Ultherapy is commonly used for lifting and tightening specific areas of the face, neck and brow. The most suitable treatment depends on your skin concerns, treatment goals and clinical assessment. Our practitioners can advise whether Thermage FLX, Ultherapy or another treatment is the best option for you.
