Forget last minute beauty treatments, stars start to prepare for their time on the Oscar red carpet three months before the big event.

In order to get a flawless complexion for high def television, major skin prep is done well before any thoughts of hair and make up.

Celebrity skin care expert and make up artist Tracy Davis - who works with names like Beyonce, Alicia Keys and Sandra Bullock - explains how it works.

"Normally clients, what they will do typically is go three months prior to the awards shows (in prepping their skin). What seems to happen is that sometimes they go into invasive products and it's methods, and what have you Botox, Restylane, and all of that. Nothing wrong with that. However, I think it is more beneficial to have a skin care regiment that they can use throughout their life. So that there is something that they can follow so that they are always red carpet ready."

Best actress Oscar-nominee Sandra Bullock, who is 45 years old and wears minimal make up, is a perfect example of a star who likes to use more natural ranges, says Davis:

"We love Sandra, and Decleor, Sandra loves this product. Demi Moore uses the Carita product. We have Brooke Shields using the Carita product. I think more and more celebrities and women a like are becoming more aware that natural is really the way to go. And their skin looks amazing... And Meryl Streep, she is a doll. She uses also the Carita products. What they found is that by using those products, it really, it is really increasing their skins elasticity. It is giving them that youthful look. When you see them live, they have beautiful skin."

As for make-up - what looks will Hollywood stars sport to grab the Oscar spotlight on Sunday (7 March 2010)?

Too Faced Cosmetics founder, Jerrod Blandino, is a make up artist who has worked with the cream of��Hollywood and gave Katy Perry her famous pin up girl look.

Fans of the brand, which boasts a nod towards the retro styles of Hollywood past, include Madonna, Kate Hudson and Gwyneth Paltrow.

Blandino spills on what he thinks will be flattering famous faces on the big night:

"The Oscar trend this season is all about ethereal feminine beauty. It is the softer side of sexy. Maybe a more bold lip, but a twist on the traditional red lip. A softer more metallic eye. It is all about lips and lashes."

And because millions of fashion fans will be tuning in to the red carpet parade - the show is great precursor of what will be big in beauty sales for spring.

Look for bright lipstick, says Blandino:

"We are going to pop the whole look with a great lip. The traditional red glamorous lip is classic. It never goes out of style, it is always fun. But, the more modern twist is bright pink. So hot. It is all over the runways all over every celebrity. You are going to want to sport this all spring long."

Actresses will also be show-casing the latest in hair designs, inspiring global fashion trends and thousands of copy-cat looks for the year to come.

Patrick Melville tends the tresses of stars like Charlize Theron, Blake Lively, Demi Moore, Heidi Klum, Halle Berry, Tom Cruise and Mark Wahlberg.

He agrees that it's all about feminine beauty this year:

"I think the hair these days is really going in a more natural feeling. I mean it is not forced hair, it is more loose, a little more romantic. It's going to be like the up-do's, soft loose chignon's. Kind of a little messy, not structured at all. The hair is going to have big open waves, very healthy, very shinny. Very soft, very touchable hair."

The 82nd annual Academy Awards will air on ABC on Sunday, March 7th 2010.
