Demand for beauty treatments is soaring. The global aesthetics market is projected to reach €22.9bn by 2028, according to analytics company Clarivate, driven by the development of more natural-looking results and the influence of social media.

"It's very hard to find statistics, because they're all private enterprises, so they don't need to release them," says Liz Dwyer (@lizdwyerbeauty), co-founder of the Future Beauty and Health Show, which returns to the RDS on March 21-22 with a line-up of Irish and international experts in aesthetics and longevity.
