Formby Labour Councillor Nina Killen said she will monitor a tattoo studio after residents raised concerns about its location.
The studio is set to open at Harington Road shops after Sefton's planning department gave the greenlight.
Cllr Killen organised a meeting for residents to quiz the owners of the tattoo studio, Karl Atkins and Michelle Davies.
Cllr Killen said: "We had a productive meeting with the studio owners, where they were able to address directly the concerns of the residents.
"Concerns included opening hours, fears over the clientele and the fact the studio is in a residential area.
"Karl and Michelle both listened to concerns and made alterations to their plans, including open hours. They have scaled open hours back from 9am-8pm Monday to Saturday, back to 10am-6pm Tuesday to Saturday with private booking only for Mondays.
"They also explained that they will not have an ostentatious sign, and it will not even feature the word 'tattoo'. They also gave assurances that they do not give tattoos to anyone who is under the influence, or under age. And they say they always refuse to tattoo people hands, faces and necks.
"The applicants received permission for the studio through devolved powers to planning officers, so no councillors had the chance to inspect the plans before approval was given.
"But I will be monitoring the studio after they have opened to make sure residents' concerns are addressed."
Cllr Killen is arranging a follow-up meeting with residents and the studio owners for September.
Cllr Killen said: "Karl and Michelle, and the residents who attended last week's meeting, all agreed to attend a follow-up meeting in September so we can assess the impact of this business on our community.
"While lots of people are opposed to this business setting up on Harington Road, it was interesting to hear a couple of local residents accept an invitation to call into the studio for a coffee so they can see for themselves what goes on in there.
"I'd like to thank everyone who came along to the meeting and Karl and Michelle for accepting my invitation to speak to concerned residents."
