Skin Care Products with Antioxidants – Store with Care! What is Oxidation?

Skin care products containing antioxidants tend to be unstable in the presence of light, air, and heat. Great ways to prevent oxidation are to open and close the lids quickly, to store your products tightly sealed in the back of the refrigerator, and to keep them wrapped in a paper towel (especially if they’re in clear packaging). Even better is if you buy products in dark or solid packaging, such as blue/brown glass or non-see through containers.

Fruits and vegetables are good sources of antioxidants.

A Few Antioxidant compounds Foods containing high levels of these antioxidants
Vitamin C (ascorbic acid) Fresh Fruits and vegetables
Vitamin E (tocopherols, tocotrienols) Vegetable oils
Polyphenolic antioxidants (resveratrol, flavonoids) Tea, coffee, soy, fruit, olive oil, chocolate, cinnamon, oregano
Carotenoids (lycopene, carotenes, lutein) Fruit, vegetables and eggs.

What is oxidation?

The loss of at least one electron when two or more substances interact. Those substances may or may not include oxygen. When it involves oxygen, the process of oxidation depends on the amount of oxygen present in the air and the nature of the material it touches. True oxidation happens on a molecular level — we only see the large-scale effects as the oxygen causes free radicals on the surface to break away. In the case of fresh fruit, the skin usually provides a barrier against oxidation. This is why most fruits and vegetables arrive in good condition at the grocery store. Once the skin has been broken, however, the individual cells come in direct contact with air and the oxygen molecules start burning them. The result is a form of rust we see as brownish spots or blemishes.

Although oxidation reactions are crucial for life, they can also be damaging.

The secret of preventing oxidation caused by oxygen is to provide a layer of protection between the exposed material and the air (an anti-oxidant in the case of skin care).
