Some facials are pure relaxation, others you have to grin and bear it in pursuit of perfect skin.
And anyone who has had a CACI facial knows that for the first time it can be a little unnerving. After all, little electrical pulses are being zapped into your facial muscles to give them a good workout. Who wouldn't feel a bit tense?
But if celebrities like Jennifer Lopez, Lisa Snowdon and Gwyneth Paltrow, say it works wonders, it's got to be worth a go.
Jade James, senior beauty therapist at Cedars health and beauty centre in Gloucester's GL1 was reassuring.
"The CACI treatments are really popular, people love them. There is a bit of a pins and needles sensation but you soon get used to it."
Originally it was a treatment to treat Bells Palsy and strokes – the electrical pulse stimulates the muscles to start them working again. The rejuvenation benefits were discovered and CACI is now used widely in the beauty industry.
Known as the non-surgical facelift, the idea is to kick-start the muscles, so they're toned and lifted, leaving the skin plumped and fresh-looking.
At Cedars the original CACI treatment can be combined with various add-on extras so you get a tailormade session to suit your skin.
I tried the CACI Ultimate 85 – the micro-current boosting lift plus three other features – microdermabrasion, a wrinkle comb to treat fine lines and a hydra mask to soothe and calm the skin.
First Jade exfoliated my skin with a tool that buffed the skin. The vibration took a little getting used to, especially around the nose area where it felt like everything rattled, and my skin soon felt very warm.
Then came the bit I was most nervous about – the electrical pulses. Using what looked like two metal rods, Jade worked around the chin area first, holding and lifting each area.
She reassured me it was on a very low setting and I could feel a *****le as she moved the rods around. It wasn't uncomfortable, but I didn't feel I could relax either. The things we do for youthful skin, we joked.
After working all over my face for about half an hour, she moved on to the wrinkle comb, gently working around the mouth area on those nose to mouth lines. She smoothed gel over the area first and then moved the comb, targeting lines and wrinkles.
By this time, my face felt so warm, I must have been as red as a beetroot. So the cooling hydra mask was sheer bliss. With hyaluronic acid and collagen, it intensively moisturises and calms the skin. As Jade used rollers to massage in the moisture, this, at last, was the relaxing bit.
By now, my skin felt calmer and as we finished the treatment, my skin had a healthy glow and those nose to mouth lines were much less noticeable. My skin had definitely had a good workout.
