Skin treatments using technology are taking off, but many still prefer traditional methods by hand

There's a curious thing happening in spas nowadays. Flick through a treatment book, and terms such as "radio-frequency waves", "ultrasound waves" or "UV lights" will pop up.

Celebrities such as Jennifer Aniston and Kim Kardashian are touting the marvellous effects of such treatments, especially as they are a non-invasive and non-surgical way to brighten, soften or tone skin.

"Today's consumer wants more from their treatments. It's not just about relaxing in a dimly lit room anymore," says Noella Gabriel, director of product and treatment development for Elemis. "There is an expectation that, even in a spa environment, there should be a more noticeable and lasting difference in the skin after a facial."

Gabriel, who has spent more than two years working with experts across the globe to create bespoke, non-invasive treatment devices, believes the results combine science with traditional hands-on therapy to offer customers "the best of both worlds".

"Twenty-two years ago, electrical and other technology for skin simply wasn't sophisticated enough, but that has changed," she says.

Nowadays, beauty treatments range from traditional treatment by hand to technology-assisted services such as oxygen treatments.

Karen Aleksich, spa director at the Mandarin Oriental, Hong Kong, says technology can stimulate cells, tissue and muscles in a way that hands cannot.

"The results are incredible with the use of technologies such as ultrasound, light therapy, microcurrents and microdermabrasion," she says. "Scars can heal faster, fine lines are reduced and deep wrinkles are softened, giving the skin a more youthful appearance."
