Suarez is currently serving a four-month global ban from competitive football after sinking his teeth into Giorgio Chiellini's shoulder during a clash between Uruguay and Italy at this summer's World Cup in Brazil.
But the 27-year-old made his first appearance for Barcelona since his £75 million move from Liverpool on Monday, coming on as a substitute against Leon in the pre-season Joan Gamper Trophy.
And when questioned about his biting problem during a press conference to mark his unveiling as a Barcelona player on Tuesday, Suarez revealed he is taking steps to correct the issue.
"It's a personal matter which I would rather not discuss, but I have been speaking with professionals [to make sure there will be no more biting incidents]," he told reporters.
"My psychologist told me to get out and offer my apologies and I did that. I now want to move on and focus on football.
"Of course I was concerned after the Chiellini incident and not just about my transfer to Barcelona, but also about my reputation as a person. But that's in the past now."
Suarez also took the opportunity to reiterate his delight at finally completing his big-money move to Camp Nou.
"I want to thank the club and all of the directors for the confidence they have had in me, and of course the coach Luis Enrique and all of the people who have supported me," he added.
"I am looking forward to enjoying myself here and enjoying the group dynamic. I've been wanting to play for Barcelona for years and it's a dream come true to be here.
"I have been dreaming of playing for Barcelona for years. All the little boys want to achieve this. I didn't think it would ever happen, so I didn't think twice when the chance came up."
The Uruguay star then went on to voice his delight with his debut in the 6-0 win over Leon on Monday, though he claims he does not consider himself the club's star signing of the summer.
"It was very exciting to make my debut. I had never played at Camp Nou before, so it was very interesting to come out and see the fans. It was unbelievable. I never imagined something beautiful like this would happen," he continued.
"Am I the star signing? Stars are up in the sky. I am just here to do everything for the team. It motivates you to play alongsides big names such as Lionel Messi and Neymar, but it's about all of the players.
"The coach has said some nice things to me, even though we didn't have an in-depth dialogue yet. He's focused on Elche for now. We will speak in more detail when my official debut gets closer."
Suarez could make his official Barcelona debut in the Clasico against Real Madrid on October 26, the day after his suspension comes to an end, and he has made it clear that he will be ready to face the Champions League holders.
"My debut against Madrid? It's still a long time. I don't think fitness will be an issue, but there's always the matter of adapting to the team.
"But I don't think there will be a problem if I'm physically alright."
