Free Radicals: What You Need to Know

To understand the way that free radicals and antioxidants interact, you must first understand a bit about cells and molecules.  So here’s a (very) brief refresher course in Physiology/Chemistry 101:  The human body is composed of many different types of cells. Cells are composed of many different types of molecules. Molecules consist of one or more atoms of one or more elements joined by chemical bonds.

As you probably remember from your old high school days, atoms consist of a nucleus, neutrons, protons, and electrons. The number of protons (positively charged particles) in the atom’s nucleus determines the number of electrons (negatively charged particles) surrounding the atom. Electrons are involved in chemical reactions and are the substance that bonds atoms together to form molecules. Electrons surround, or “orbit” an atom in one or more shells. The innermost shell is full when it has two electrons. When the first shell is full, electrons begin to fill the second shell. When the second shell has eight electrons, it is full, and so on.

The most important structural feature of an atom for determining its chemical behavior is the number of electrons in its outer shell. A substance that has a full outer shell tends not to enter in chemical reactions (an inert substance). Atoms seek to reach a state of maximum stability, an atom will try to fill its outer shell by:

  1. Gaining or losing electrons to either fill or empty its outer shell;
  2. Sharing its electrons by bonding together with other atoms in order to complete its outer shell.freeradical1

Atoms often complete their outer shells by sharing electrons with other atoms. By sharing electrons, the atoms are bound together and satisfy the conditions of maximum stability for the molecule. Normally, bonds don’t split in a way that leaves a molecule with an odd, unpaired electron. But when weak bonds split, free radicals are formed. Free radicals are very unstable and react quickly with other compounds, trying to capture the needed electron to gain stability. Generally, these weak bonds attack the nearest stable molecule, “stealing” its electron. When the “attacked” molecule loses its electron, it becomes a free radical itself, beginning a chain reaction. Once the process is started, it can cascade, finally resulting in the disruption of a living cell.

Some of these weak bonds arise normally during metabolism. Sometimes the body’s immune systems cells purposefully create them to neutralize viruses and bacteria. However, environmental factors such as pollution, radiation, cigarette smoke, and herbicides can also spawn free radicals. So why should you care about this? Free-radicals initiate the deterioration of the skin’s structural support and decrease the elasticity, resilience, and suppleness of skin.  They are often tagged as the culprit in the case of wrinkles, loss of skin elasticity and suppleness.

The vitamins C and E, are thought to protect the body against the destructive effects of free-radicals. Antioxidants neutralize free-radicals by donating one of their own electrons, ending the electron “stealing” reaction. The antioxidant nutrients themselves don’t become free radicals by donating an electron because they are stable in either form. They act as scavengers, helping to prevent cell and tissue damage that could lead to cellular damage and disease.

Anti-Aging Antioxidants– What You Should Know

orange-juice_1When it comes to anti-aging ingredients, the research is abundantly clear– antioxidants reign supreme. Not only do antioxidants combat the free-radical damage that is responsible for the visible (and hidden) signs of aging, they also enhance the effectiveness of sunscreens in preventing sun damage. Indeed, during the day, the combination of antioxidants plus sun protection is a strong defense against many signs of aging, including wrinkles, dullness, and discoloration. At night, dosing your skin with a range of antioxidants will promote cellular repair and healing.

There are hundreds of trendy antioxidants that show up in skincare lines, but antioxidants don’t need to be exotic or have a good marketing story to work brilliantly. Despite what marketers may claim about Tibetan berries or about melons harvested at dawn in the south of France, what matters most is treating your skin to a variety of antioxidants. That’s why Dermaworks Medical Aesthetics Clinic takes a cocktail approach!

Vitamin C is a potent antioxidant that works particularly well for treating wrinkles, dullness, and brown spots. This vitamin is considered an anti-aging superstar. When applied, vitamin C increase collagen production (including dermal collagen, which is significant in the fight against wrinkles) it also reduces skin discolorations, strengthens the skin’s barrier response, enhances skin’s repair process, reduces inflammation, and helps skin better withstand exposure to sunlight, whether protected by sunscreen or not. Amazing right?

Vitamin E is another well-known antioxidant that provides significant benefits to the skin. Vitamin E works in several different ways to protect cell membranes from oxidative damage and from the early stages of ultraviolet light damage. It also works in powerful synergy with vitamin C; that is, our powerful cocktails that contain both vitamins C and E are doubly as beneficial!

Ferulic Acid is also found in our products and has been demonstrated to be an antioxidant extender. Vitamin C is very problematic in skin care due to its highly oxidative state.  There are several factors that must be controlled for topical Vitamin C to be effective.  One of those factors is stabilization once it’s exposed to air, or moisture, where Vitamin C quickly oxidizes. Ferulic Acid does just that. Combined with vitamin C it works to stabilize the vitamin, preventing the oxidation and delivering you better, longer lasting results!

When it comes to treating your skin to antioxidants, remember the old saying “Strength in numbers.” When the antioxidants described above are combined and working together, and reinforced with daily use of sunscreen, the results are remarkable! Trust us.
