If we want to look at our anti-aging practices from an informed and discerning perspective, it’s good to know what’s going on in there that causes wrinkles (and other not-so-fun manifestations of skin aging). So far, we know about three main things that happen in the skin when damage is caused. Click HERE for the 1st Villain I wrote about. Here’s the 2nd biochemical phenomenon in my series:
• The Villains: MMP’s
Matrix Metalloproteinases (MMPs) are enzymes -envision Pac-Man!- activated by inflammation. Inflammation can be caused by elements like UV exposure and infrared radiation. MMPs are not cool because they contribute to the breakdown of collagen. And as if that wasn’t bad enough… they also work to inhibit new collagen formation.
For a scholarly article type of resource, check out this white paper on The National Center for Biotechnology Information website. They say Matrix-degrading metalloproteinases are key mediators of collagen degradation that is observed in photoaged skin. Key mediators? Oh man!!
Yikes! What to do now???
Don’t freak out, its just one of the biochemical phenomena that results from CHRONIC damage and UV exposure. Let’s be proactive about this… Since we know MMPs are expressed as a result of UV and IR, we have a shot at preventing by using great SPF and using antioxidants.

Until Next Time, Stay Fabulous (and Informed!) my friends!
