Chloe Sevigny has her theories as to how she's managed to defy her age.

"I think it's not having had a baby yet," the 41-year-old actress tells W magazine when asked about her youthful glow. "Because I think the baby wear and tear and stress on your body is part of the reason why people say, 'Why do you still look so young?' I really think that that unfortunately ages women, especially when they have children in their 30’s, not in their 20’s."

In addition to crediting her lack of childbearing for her good skin, Sevigny also admits that it has a lot to do with her genes. "So I think, first and foremost, it’s that and genetics," she adds. "And then I’m really into all the things they tell you to do, like moisturizing. I go to Dr. Colbert, who is this fancy dermatologist."

There is one procedure the Big Love star has yet to try. "I haven’t really gone the Botox route yet," she admits. "But [Dr. Colbert] does lasers and very expensive facials and stuff like that."

Sevigny does confess that she is a little "scared" of the aging process. "I don’t do a lot of caffeine. But once I hit 40, I feel like things are starting to happen now that aren’t very exciting," she says. "I mean, what do you do? Do you let it happen? Or do you start the preventive measures? It’s kind of terrifying. The under-the-eye thing, there really isn’t much to do for that."

The actress says she's working on "being confident" in her 40s. "It’s a big mental thing," she explains. "I just got back from Cannes and there is so much emphasis on your looks, and fashion, and all that. I’m trying to have a healthy remove, and I’m trying not to beat myself up."
