Beauty salons, spas, tattoo parlours and nail bars are welcoming back their first clients for almost four months, as lockdown restrictions ease further in England.
But some treatments, such as eyebrow threading, are still banned, leaving many salons unable to reopen.
In Scotland indoor shopping centres are allowed to reopen.
In Wales, pubs, bars and restaurants can start serving customers outdoors, while hairdressers can also reopen.
Businesses will be required to follow guidelines to reduce the spread of coronavirus - and treatments which involve work directly in front of the face will not be available.
Government guidance says services including face waxing, eyebrow threading, eyelash treatments, make-up applications and facials should not be provided because of the greater risk of Covid-19 transmission.
Naresh Bhana, who runs Flamin' Eight tattoo studio in north London, said the business was only taking advance bookings, so "you can't walk off the street unannounced".
"We can accommodate two or three being tattooed but we stagger their start times," he said. "Work areas are four metres apart. Everyone's wearing masks. Clients will wear visors as well."
He has created a commemorative tattoo for his wife to mark the reopening.
