It may seem like a cliché to say that Carnie Wilson, even when she was heavy, had such a pretty face – but she really did. Now that she weighs 150 pounds less, she still has a gorgeous face with unusually nice skin. When asked how she keeps her complexion so lovely, she laughs and gives credit where it's only partially due: her makeup artist. In fact, Carnie has been getting facials since she was 10 years old.

"My mom had acne and she would go for a facial once a month and take me along," Wilson says. "She taught me from a very early age to pay attention to my skin and nails and it's just a habit for me."

In addition to her facials, Wilson is practically religious about drinking 64 ounces of water a day. She says it helps with her diet efforts as well. To keep her complexion clear from the outside, she washes her face twice a day with a milk-based cleanser and uses a high-quality moisturizer. She also swears by essential oils, which she dabs on around her eyes.

"Essential oils not only moisturize but they have natural cleansing properties," Wilson says. "But the big connection is water. If anyone with skin problems drinks plenty of water, it will fix whatever is wrong."
