What is CFU-elife?
CFU-elife is a new generation of HIFU (High Intensity Focused Ultrasound). It delivers focused ultrasound energy beneath the skin's surface, to the deeper skin layers and the supportive layer used in surgical facelifts (the SMAS). This creates tiny points of heat that stimulate your body to produce new collagen, gradually tightening and firming the skin.
How it works
The energy is delivered to a specific tissue layer at a precise depth and spacing, customised to the result you're looking for.
For the face and neck: treatment leads to gradual tightening and firming. 1 to 2 treatments are recommended in a year, depending on age and skin condition. Results develop over 3 to 6 months and last up to one year.
For underarm sweating
The focused ultrasound treats the sweat glands responsible for excessive sweating (eccrine glands) and the glands responsible for odour (apocrine glands). 2 treatments are recommended, one month apart.

Frequently asked questions
Does it hurt?+
Most people feel warm prickling, heat or a deeper aching sensation as the energy is delivered, which stops as soon as each pass ends. Libbie will check how you're feeling throughout and can adjust the treatment. The area can feel tender to the touch for a few days afterwards.
Is there any downtime?+
Downtime is minimal and most people return to normal activities straight away. The area may feel tingly or tender for a few days, and any redness usually settles within a few hours.
How many treatments will I need?+
For the face and neck, 1 to 2 treatments in a year, depending on age and skin condition. For underarm sweating, 2 treatments one month apart.
When will I see results?+
Results are natural and gradual, developing over 3 to 6 months.
How often should I repeat treatment?+
A yearly treatment is recommended to maintain results, as the skin continues to age.
Can it be combined with other treatments?+
Yes. Skin boosters can be done 1 week before CFU-elife, and collagen stimulators 1 month before.
Who is it best suited to?+
Results tend to be best for mild to moderate skin laxity; Libbie will advise whether it's right for you.
Can you guarantee improvement?+
No. As it isn't surgery, results depend on how your body responds by building new collagen, and they vary from person to person. Most people see an improvement, but some see little or no change. Libbie will talk through realistic expectations at your consultation.
Is it suitable for my skin type?+
It's suitable for most skin types; Libbie will assess yours at consultation.
