How do Antioxidants work for you?


Antioxidant! You hear that word everywhere, but what are they and how do they work?

To understand what an antioxidant is, first you need to understand what an oxidant is. An oxidant comes by many other names including; Free Radical, reactive oxidative species (ROS). It is all the same thing.  Put simply, the oxidant is a robber with un-paired electrons.

It’s quest? To attack and steal electrons from surrounding stable molecules to satisfy their own selfish needs. As a result that original stable molecule is unable to perform its function properly instead it turns into an oxidant itself and hunts other molecules for electrons. The whole process can become one big chain reaction consistently breaking up molecules. If they begin to attack the DNA or mitochondria it could lead to cell death.

The role of the antioxidant is to satisfy the oxidant or robber by giving it an electron before it can steal one. An antioxidant stops the chain reaction and the cell demise.

Too many oxidants has found to overwhelm the antioxidant defense mechanism in the skin causing oxidative stress and photo-damage. Factors that contribute to excess oxidants are; UV-radiation, x-rays, diet, alcohol and pollutants including tobacco and car exhaust.  Aside by breaking up important proteins and molecules and prevent them from doing their job. The increased oxidant presence has been linked to activate matrix-metalloproteinase (MMPs). MMPs are a family of pro-lytic enzymes which decompose collagen, elastin and other    connective tissue proteins, consequently more   oxidants relate to more connective tissue breakdown and formation of wrinkles and photo-aging.

Topical antioxidants are in abundance and come in a variety of forms, some are directed at the cell membranes and oils of the skin (hydrophobic antioxidants) E.g. Vitamin E and Vitamin A. Some are directed to the contents within the cells (hydrophilic anti-oxidants) E.g. Vitamin C.

All David Deans Skincare products contain useful functioning antioxidants.  For example the David Deans Silk & Velvet Night Cream contains a mixture of these hydrophilic and hydrophobic antioxidants plus natural botanical blends including rosehip oil. This night cream will absorb and continuously work in the night to fight oxidants and soften ageing skin.
