What Does an Antioxidant Serum Do?

There’s no shortage of factors that can attack the health of your skin including UV rays, pollution, and your diet. All of these aging factors have one thing in common: free radicals.

If it’s been a while since your last biology course, free radicals are unstable and highly reactive molecules, and they can be found all around us. These molecules stabilize themselves by latching onto and stealing electrons from other sources, including your skin cells!

These thieving molecules weaken the skill cell and thus promote the aging process. This is where your antioxidant serum becomes the hero of the story!

Antioxidants will donate an electron to stabilize (neutralize) the free radical, saving your skin cell’s DNA from damage, and helping to repair the damage that’s already been done.

How to Select the Best Antioxidant Serum

Look for key antioxidant-packed ingredients, including Vitamin A (retinol or retinoic acid), Vitamin C (ascorbic acid), Vitamin E (tocopherol) and Vitamin B3 (niacinamide), and check the packaging. Antioxidants must be protected from the environment in an opaque, airtight container to extend your product’s shelf life.
