Why The Antioxidant CoQ10 Is So Good For Your Skin Barrier*

Antioxidants deserve all of the praise they get in the skin care department. By targeting free radicals, they protect the skin and buffer it from oxidative stress.* "Free radicals are unstable molecules that can affect your cells or DNA," says board-certified dermatologist Zenovia Gabriel, M.D., FAAD. Free radicals are called "unstable" because they are missing an electron. This is a problem because atoms don't like to have uneven electrons, and when they are unbalanced they are greedy. (One way they are greedy is they take electrons from healthy cells. Those healthy cells are then turned into, you guessed it, free radicals. The cycle continues.) Antioxidants work by donating one of their own electrons to stabilize the molecules. They are one of the most important actives you can add to your routine to promote healthy skin and longevity, full stop.* 

But antioxidants are not a monolith. See, while they all help neutralize free radicals—most have their own individual roles in the body and skin that make them unique. For example, we look to vitamin C and E to promote collagen production, as they help with synthesis and cross-linking.* We look to niacinamide for water retention.* We use astaxanthin for photoprotection.* The list goes on!

A little briefer on CoQ10: It is a fat-soluble compound that's found in all your cells. In fact, it's the only lipid-soluble antioxidant your body produces naturally. It's known as a "coenzyme" because it's needed for other enzymes to function. Additionally, it plays a vital role in mitochondrial health, meaning it critically supports cellular energy.* All in all, it's a pretty impressive nutrient-like compound. 

But back to the lipid peroxidation part—uh, what is it exactly? Research shows us that lipid peroxidation1 occurs when free radicals and oxidative stress unbalance and compromise cell membranes and lipids. You can probably understand why that's not great for your skin: Your skin cells and skin barrier need lipids to stay intact and healthy. Luckily oil-soluble vitamins can help. Enter: CoQ10.* As we noted, your body produces it naturally, but as you get older, it declines, meaning it may be beneficial to supplement with the antioxidant.* Honestly, at any age you may just be interested in a targeted dose of this skin-loving bioactive.*
