Forget "Making Over America"-- fashion expert Trinny Woodall has been busy making over herself.

In a revealing photo shoot and interview with the May issue of Britain's Tatler magazine, the 46-year-old former "What Not to Wear" host sports nothing but her birthday suit and bares all about her pricey pursuit to keep her skin -- much like her wardrobe -- wrinkle free.

"I will admit I am quite obsessive about the world of anti-aging," Woodall tells the magazine, according to the U.K.'s Daily Mail.

"But you know what? I love it. I can't deny that. We might not all have had the good fortune to be born with a perfect complexion, but we can make it happen, with a little help."

And Woodall has not been shy about asking for assistance. Her first step toward achieving a flawless face was having London skin-care specialist Dr. Jean-Louis Sebagh -- who counts supermodel Cindy Crawford among his clients -- zap away acne scarring from her teens with laser treatments.

That was followed by Botox treatments three times a year in her 30s, each visit costing an eyebrow-raising $609. "I judge when I need a top-up of Botox by looking in the mirror to see if I can move more than half my forehead," muses the divorced mother of one.

A fan of $213 facial peels, Woodall -- who doles out style advice on TV and in print with fellow fashionista Susannah Constantine -- has no intention of going under the knife but is happy to have other sharp objects get under her skin: Besides being pumped with $380 vitamin injections, she also had the dark circles under her eyes filled in seven years ago.

And, Woodall tells Tatler, "For the past three years I have been enjoying the painful pleasures of Fraxel, a laser that tightens and lifts the skin, especially around the jawline." The cost: $1,218. Ouch, indeed!

Ultimately, the no-nonsense Woodall's best anti-aging tip is for women to stop cutting into their skin and simply cut the B.S.

"I think it's unnecessary to go all coy and French and pretend you're just amazingly beautiful naturally," she tells Tatler. "I would advise women not to be shy about admitting they've had Botox -- it just shows you want to look your best -- and there's nothing wrong with that."
