The 56-year-old actor teamed up with Mending Kids International, which performs life-saving surgeries for children and treated a 10 and an 11-year-old girl from Honduras to the A-list lifestyle in Hollywood hotspot the Grove, reported TMZ online.
Gibson, took the two girls, who have both had extensive facial reconstruction surgeries, out for a gourmet lunch, followed by ice-cream, and a spot of window shopping.
He also took them to a high-end American Girl doll store where they were able to create their own lookalike dolls.
"It was really fun spending time with Karol and Sara. They have been through so much and are just so inspirational to everyone who meets them," Gibson said.
"At home, these girls couldn't leave their homes for fear of being tormented. Now, they are walking through one of the most popular tourist areas of Los Angeles," he added.
The star is further pledging his commitment to the organisation by participating in the Mending Kids celebrity poker tournament this weekend in West Hollywood.
Gibson is trying to improve his image after his reputation was tarnished by assault claims made by his ex-girlfriend Oksana Grigorieva.
The actor was sentenced in March 2011 to three years' probation - including a 12-month domestic violence counselling programme - over the attack on Grigorieva, who is the mother of his daughter Lucia.
