Have you ever looked into the mirror and asked yourself, "How did I wake up with these wrinkles?" Well, you really haven't been paying close attention to your skin. According to dermatologist Dr. Amy Wechsler, aging doesn't happen overnight.

The collagen in our skin slowly breaks down as we grow older. However, there are three factors that can speed up this aging process: excessive sun exposure, smoking and chronic stress. Understanding and eliminating these bad habits can help you to live a more beautiful life.

"I think we should embrace our age no matter what it is -- the goal is to feel and look as healthy as possible," adds Dr. Wechsler.

Watch the video above to find at which age collagen usually starts to break down and exactly how these three factors of aging affect your skin.

Here's to looking and feeling forever young:
