In "The Sugar Detox: Lose Weight, Feel Great, and Look Years Younger," authors Dr. Patricia Farris and Brooke Alpert tells us sugar goes straight to wrinkles in our faces. But is that really how the process works?

If you are plugged into mass media in the United States, you couldn't have missed the news surrounding recent publicity of the idea that sugar causes aging skin.

In a newly released book The Sugar Detox, a dermatologist named Patricia Farris and her co-author beauty expert Brooke Alpert tell their readers that sugar is the cause of crankiness, food addiction, "brain fog," and a variety of skin problems ranging from acne to wrinkles. But is that really how the process works?

There's good evidence that sugar can be addicting. Chomping down a sugary dessert or breakfast food leads to a quick surge of glucose in the bloodstream. The pancreas releases its stored insulin to keep all that excess sugar from literally catching fire in a process called auto-oxidation. This protects the linings and DNA of cells over almost all of the body (except the brain and the ovaries in women). 

Because the process that triggers the blood sugar-lowering hormone insulin also releases the blood-sugar raising hormone glucagon, every time your body experiences a surge of sugar in the bloodstream it both stores sugar in fat cells and releases sugar from the liver. At some point the liver can't keep up with the constant demand to release sugar (to make sure that insulin doesn't work "too well") and you don't have energy when you need it.

The solution? More sugar! In this way, eating sugar becomes as insidious a habit as smoking cigarettes or even snorting cocaine. But does this process mean that you'll suffer bad skin, too?

Probably not.

Skin ages in part due to a process called glycation. Constant exposure to high levels of sugar in the bloodstream lead to the formation of a "caramel coating" on certain proteins on the surfaces of nerves, of blood vessels, and of the connective tissue underlying the skin. Sugar attaches itself to the proteins that give skin its suppleness and "give," proteins called collagen and elastin. 

The skin loses its elastic ability to "bounce back" when it has to move with muscle motion, with the result that it forms sags, bags, and wrinkles. But is this process inevitable? And is there some way to reverse it years of being a sugarholic are beginning to show up in your face?
