"It is what it is," Anderson tells PEOPLE. "Besides, I feel like I'm getting younger all the time."
The star, who has authored a new coffee table photo book, Raw, also reveals that she tried – and didn't like Botox.
"I am the last person to try Botox but I did," she says. "I felt like my eyes sunk into my head so far that I didn't look look like me anymore! I'm not into all that stuff."
"I think a little bit of maintenance is good. There are things we can do to perk ourselves up. Some people go to far. I'm not obsessed," she says. And she's got those coveted good genes to thank as well. Adds Anderson: "My mom looks great."
Her role models for aging gracefully? "I love Jane Fonda and Brigitte Bardot. It's like the old saying goes: 'Beauty comes from within.' It's about embracing it and feeling great about what you have. And doing the best for you."
Pamela Anderson's new book, Raw
BenBella Books, Inc.
For Anderson, that also means eating vegan, which she now showcases on her new online cooking show The Sensual Vegan, and devoting herself to environmental and animal rights activism, through her Pamela Anderson Foundation.
"Doing good things keeps you young," she says.
The star is also excited about her new book, featuring photographs by her good friend Emma Dunlavey. Raw is "a fun look back, a behind the scenes of me being silly in hotel rooms and pages of my journaling. Sometimes when I'm inspired, I write poetry – well, if you want to call it that. They were wild times. Not that I don't have fun and crazy times these days."
