Look younger with Whiter teeth. GLO Science.

They say if you aren't whitening, you're yellowing.

We associate beauty with youth, and for some reason baby teeth are just naturally freakishly white. So if you're not whitening, your smile might be making you look older than you are.

Teeth whitening has come a long way these past few years. Who hasn't heard of Crest WhiteStrips? Yes, they work, but only if you're VERY patient and willing to put up with the goo and mess in trying to keep them in place every time you use them. Speaking of, you'll need to use them a lot to see real results.

And we've all heard of ZOOM, the fastest way to whiten, especially how painful it is. The sensitivity lasts a long time due to the strength of the bleaching agent that's used.

So if you're looking for a solution to whiten quickly without sensitivity, there is a new at home device on the market that you should know about called the GLO Brilliant Personal Teeth Whitening Device, $199 Available at Sephora and gloscience.com.

This system was developed by a dentist, Dr Levine, and is a new approach to whitening using heat and light with a patented gel formula. Dr Oz named it one of his top anti-aging products and beauty editors swear it's the easiest way to whiten teeth without sensitivity.

It looks like an iPod, but easier to use. Charge it up, apply the gel to your teeth - connect the mouthpiece and press power for 8 minutes to get one step closer to whiter teeth. Up to 5 shades whiter in 5 days, without sensitivity. 

The set comes with 10 G-vials of gel which is enough for 40 applications or sessions. By purchasing additional mouthpieces everyone in the family, over 12 years old, can have beautiful pearly whites. I think Americans now have the whitest teeth in the world!

Blue Light Therapy Zit Zapper - Tanda High Tech Beauty

They say that beauty comes in all colors ... and so does the light we use on our skin. Blue light therapy is often used in clinics to treat and prevent acne and now there are gadgets available so you can do it yourself at home.

One of the smallest devices using blue light therapy on the market that can really deliver is the Tanda Zap for $49. It uses the same technology as the in-clinic machines used by dermatologists and here's why it works.

A zit forms when a pore is blocked with oil according to Acne.org. Most of the time the oil will drain but if it becomes blocked bacteria are formed. One of the bacteria creating a zit is called P. acnes. It proliferates, becomes inflamed and swells. White blood cells rush in to try to fight it away, which is how you end up with a white head. 

Blue light therapy works on killing acne because it delivers oxygen inside the pore and P.acnes bacteria cannot live in an oxygen rich environment. Benzoyl peroxide, a commonly used OTC product used to treat acne works in the same way - by introducing oxygen into the pore, but it can be very drying to the skin.

No matter what your age, zits continue to pop up. I love the Tanda Zap to treat that unexpected little monster that shows up and I never travel without it!  This device is designed for spot treatment and has 1000 two minutes uses and can be used 2-3 times a day on the same area safely. There is also a larger version called the Tanda Clear if you are interested in treating a bigger surface area for $195.

Using a Green Screen - Behind the Scenes in Filming a Commercial

I wanted to share with you today a little bit of a model's life and give you an idea of what it looks like behind the scenes using a green screen when filming a commercial. The magic of the green screen is incredibly fascinating to me. For this commercial we were never in an office, the people walking by and sitting around me were never filmed in a shot together. The only props used were a table, chair, cardboard box and 2 one dollar bills. It is so incredible what production can make appear real.

Watch the Mix & Win Commercial

Behind the scenes shots

Some professional advice for those of you reading this that are in the industry: Never wear green when you are a guest on a television set interview that might have an artificial looking backdrop or if you are bringing wardrobe for a commercial job. You might be placed in front of one of these screens and in editing what they will do is block out all the green and if you are in green that may include parts of YOU! Also be aware that blue screens are gaining in popularity as well so check in to see which it might be.

Some practical advice: Not everything is as it appears to be when you see something on television. Big stars insist on softening filters to disguise aging faces, and photoshop is well, you know, the magic eraser of everything. There is even a liquifying tool. Never hold yourself to that standard or make comparisons of your individual beauty based on ideals that aren't 100% real. Don't get fooled or insecure. Confidence in and of itself is extremely attractive!!

Kardashian's Fake tans and more with new Self-Tanning Line

Just in time to get ready for your Spring Break, the Kardashian's launch a new line of self tanners called  Kardashian Sun Kissed  next month. 

According to Women's Wear Daily the line is priced between $12.99 and $19.99 and includes 4 products exfoliator, sunless lotion or spray and bronzer. 

A tan makes everyone feel like they look skinnier, but we all know how dangerous the sun is to our skin so I love that they are promoting sunless color. Promoting fake color I can get behind, but I wish they would have gone a little less Fake in their photo - so very, overly photoshopped don't you think?

I think everyone loves a bargain, but when it comes to my skin I usually never cheap out, but sometimes we don't need to spend a fortune to find a great product that works. So many times I have been disappointed by products that I've spent too much for. Sound familiar? Well you and I are not alone; here's the science behind it  

A study from Duke University published in the Journal of the American Medical Association found that people believed that a more expensive placebo pill actually worked better just because it cost more. It seems that the more expensive a product is the more convinced you are that it must be better. 

Aging happens, to all of us ... our fibroblast that produces collagen and elastin lose it's zing, but you can't start fighting the signs of aging soon enough, and there is never a better day to start than today. A couple ingredients you should look for that can help reduce the appearance of wrinkles are amino-peptides and hyaluronic acid. That's where Olay's Regenerist Micro-Sculpting Cream can help. It contains both, and is endorsed by Good Housekeeping over luxury, $250 super-creams. It's also won Allure's Reader Choice pick in 2012, 2011, 2010, 2009, and 2008.

At $25, Olay's Regenerist Micro-Sculpting Cream proves that you don't always get what you pay for, in this case you get sooooo much MORE!
