Davidson, who has around 100 tats, appears in a new Smartwater advert, in which he can be seen sitting in a chair pretending to get the ink lasered off.
"I've made a lot of questionable choices, and a couple of them need removing," the 27-year-old comedian says to the camera, as a woman works on removing ink from his left arm.
"But now I'm trying to make smarter choices, hydrating with Smartwater and stuff like that."
Speaking to PeopleTV as he launched the new ad, Davidson said that - in real life - it's actually been 'about four or five months' since his last session.
"We're shooting some stuff and it takes like a month for it to heal. But like it's pretty much off this hand," Davidson said, holding up both hands to show off the faded ink.
"I get my next treatment [in] like a month or so. They said by the time I'm 30, they should all be gone. So they got like two more years left of this."
Earlier this year, Davidson revealed that he made the tough decision to have his tattoos removed because of his passion for acting - having feared they may hinder his prospects.
Appearing on Late Night with Seth Meyers in May, he said: "I didn't think that they would put me in stuff.
"I thought after SNL it was a wrap."
Davidson continued: "I honestly never thought that I would get an opportunity to act and I love it a lot.
"It takes like three hours - you have to get there like three hours earlier - to cover all your tattoos. For some reason, people in movies, they don't have them that much."
Davidson told Meyers that 'burning off' the tattoos was worse than getting them, explaining: "Not only are they like burning off your skin, you're wearing these big goggles so you can't see anything.
"The doctor's in there with you. So before he goes to laser each tattoo, you have to hear him announce what the tattoo is, to make sure if you want to keep it or not."
He joked: "So I'll just be sitting there all high off the Pro-Nox, which I actually quite enjoy.
"It's actually pretty fun. And then, all of a sudden, I'll just hear, 'Are you keeping the Stewie Griffin smoking a blunt?'"Featured Image Credit: Universal Pictures
