MODEL and TV personality Lisa Selesner's beauty regime is fastidious, to put it lightly.

Monaco-born, Hong Kong- based Selesner - better known as Lisa S and who appears as a mentor in reality competition SuperModelMe - doesn't just treat her skin topically.

She and her husband, actor Daniel Wu, keep healthy by exercising three times a week. They also incorporate lots of brown rice and fish into their diet.

The effects are impressive. "Your immune system, your hair, your skin and even your sex drive, all improve," she told my paper in a recent interview.

Selesner will do pretty much anything to keep her skin clear. "I am, like, freaky deaky about this stuff," she said with a laugh, adding that, until a few years ago, she went so far as to wash her face with mineral water.

There's a reason she is so rigorous when it comes to her skin: She suffered from acne problems in her early 20s.

"Acne is just the most debilitating thing," she said.

Thankfully, popular American brand Proactiv - endorsed by the likes of Jessica Simpson and Katy Perry - changed her life. Selesner discovered it about 15 years ago when her mum called her at 3am one night after seeing an infomercial on the brand's three-step system.

Though it's "just a drugstore brand", Selesner swears by the award-winning product.

Of course, she also uses other "branded" products. "I am an absolute sucker for 'miracle' products," she said. For example, after learning that the Duchess of Cambridge, popularly known as Kate Middleton, uses Lancome's new serum, Visionnaire, she got herself a bottle.

The product is an advanced skin corrector that fixes wrinkles, large pores and uneven skin tone.

It's clear that Selesner will leave no stone unturned when it comes to beauty. She has even tried cosmetic surgery.

She revealed that she had surgery 11 years ago to remove fatty pockets under her eyes that always made her look tired.

And there are days when she wishes to be "a cup size bigger". For now, though, she has no plans for further surgery.
