No matter where we live and work, our skin is exposed to a variety of environmental irritants that include:
- Air/water pollution;
- Airborne dust;
- Blue light from our electronic devices; and
- Ozone from machines like indoor air conditioners.
These irritants both directly damage our skin over time and lessen the effectiveness of our skin care products by disrupting various aspects of our internal cell repair and regeneration processes1.
Thankfully, scientific research has given us not just a greater understanding about how these irritants create damaging free radical molecules, they have also identified antioxidant remedies we put in most of our products (see our Science section).
Damaging Free Radicals
We may have all heard about free radicals by now, but just what are they and from where do they come?
When our skin comes into contact with oxygen, it undergoes a normal and healthy process knows as oxygenation, or the metabolization of oxygen in our cells. Think of it as our cells feeding on oxygen and helping to regenerate its replacements by creating of new molecules called Reaction Oxygen Species or ROS. If a cell is eating its oxygen and either the oxygen or the cell is damaged by an environmental irritant, it increases the odds that ROS molecules called free radicals will be created2.
These free radicals are really just malformed molecules with unpaired electrons, making them inherently unstable and damaging to our skin as they rush around trying to fix their unpaired status. Another way to look at this is imagining these "freak" molecules know they have an odd number of electrons and it's making them crazy. So crazy in fact, they will knock electrons off of otherwise healthy molecules in search of another freak with whom to mate and even everything out. All this knocking around can create a chain reaction that leads to free radical colonies in our skin.
Left untreated and unprotected against these, our skin will produce ever larger free radical colonies which leads directly to skin dullness, wrinkles, lines and premature aging. Thankfully, we have an effective way to combat these mutant molecules.
Study after study has emerged over the years demonstrating the effectiveness of various antioxidant families in eliminating free radicals from our skin3. Scientists have established the following facts:
- Antioxidants derived from vitamins, amino acids, fruits, vegetables, other plants and animals (we do not use animal products in our formulas) are effective in fighting free radicals; and
- Antioxidants work more effectively together than any single antioxidant4.
Not surprisingly, not all antioxidants are created equally nor do they work quite the same way. For example, vitamin A contains two totally separate antioxidant families - carotenoids and retinoids. We do not use most retinoids in our formulas because of emerging research questioning safety when exposed to UV sunlight5. Meanwhile, a carotenoid superstar, astaxanthin, is featured in several of our formulas.
The VU Perspective
We love antioxidants and we source them from vitamins C,E & A along with amino acids and a wide variety of plants. We liberally pepper thoughtful antioxidant blends throughout our lineup - from cleansers to moisturizers and boosts.
If you are looking for antioxidant superstars, then please consider our serums and treatments:
- Free Radical Defense Serum - our antioxidant champ - combines a whopping 18 different antioxidants including some with the highest known antioxidant concentrations according to the ORAC* scale;
Urban Defense Gel contains state-of-the-art antioxidants that target skin damage caused by blue light and other urban environmental irritants; and
Ultimate C&E Serum combines stabilized, time-released vitamin C with vitamin E which makes the vitamin E antioxidants 50 times more effective at neutralizing free radicals.
