Ever since we first saw Kristin Davis burst into the scene as the conniving Brooke Armstrong on the original Melrose Place, followed by her portrayal of the sophisticated, yet naive, Charlotte York on Sex and the City, I think we've all been mesmerized by her stunning, ageless looks. In fact, many of you agreed that the actress barely looks a day older than when she first became famous back in the mid-'90s. When it comes to beauty, there's no doubt Kristin, now 44, has got some fountain-of-youth secrets to spill. For the October issue of Self, for which she shares the cover with her Couples Retreat costars, Malin Ackerman and Kristen Bell, each of the women spill all their beauty secrets. Find out Kristin's at the link below.

Here are the highlights:

• On her mother's influence: "My mother was a great example of beauty because she was true to herself. She never wore makeup. She was wearing Birkenstocks before they were in. It was good to grow up with a woman so confident she didn’t need to put on lipstick."
• On staying smoke-free: "The best beauty gift I’ve ever given myself is not smoking. I get so upset when I see girls in their 20s smoking. When you’re young, you think you’re never going to get wrinkles or cancer. I am in my 40s, and I've seen a lot. It's not fun to watch your friends go through cancer."
• On what keeps her centered: "If you want to summon confidence, go to yoga. It’s about tuning in to yourself on the inside. If you start thinking, I’m not thin enough or whatever enough, you can tune back into that powerful place. It gives you a sense of your self."
• On tanning: "I am a big sunscreen devotee. I wear SPF 30 or 50 every day. In Couples Retreat, we were supposed to be in Bora-Bora and be tan, but I get a rash from most self-tanners. The filmmakers wanted me to lie in a tanning bed, and I said, 'No, I can’t do that. My dermatologist would kill me!' So I found this great organic self-tanner, called Chocolate Sun ($40). It’s a lovely lotion that smells like chocolate and doesn’t streak."
