People skin look old and people look old why?
James asked:
Quote free radicals are basically rogue particles that bounce around inside your cells, damaging your cells as they go. This causes your cells to deteriorate over time, which in effect is the aging process. Theoretically, eliminating some of them slows the damage rate, and the aging process as well. quote
How do these free radicals Antioxidants or call them rogue particles get in the cell and damag it or make people look old or make the skin look old.
I’m sure there are many Antioxidants that may do it.

Free radicals play an important role in a number of biological processes, some of which are necessary for life, such as the intracellular killing of bacteria by neutrophil granulocytes. Free radicals have also been implicated in certain cell signalling processes. This is dubbed redox signaling.
The two most important oxygen-centered free radicals are superoxide and hydroxyl radical. They are derived from molecular oxygen under reducing conditions. However, because of their reactivity, these same free radicals can participate in unwanted side reactions resulting in cell damage. Many forms of cancer are thought to be the result of reactions between free radicals and DNA, resulting in mutations that can adversely affect the cell cycle and potentially lead to malignancy. Some of the symptoms of aging such as atherosclerosis are also attributed to free-radical induced oxidation of many of the chemicals making up the body. In addition free radicals contribute to alcohol-induced liver damage, perhaps more than alcohol itself. Radicals in cigarette smoke have been implicated in inactivation of alpha 1-antitrypsin in the lung. This process promotes the development of emphysema.
Free radicals may also be involved in Parkinson’s disease, senile and drug-induced deafness, schizophrenia, and Alzheimer’s. The classic free-radical syndrome, the iron-storage disease hemochromatosis, is typically associated with a constellation of free-radical-related symptoms including movement disorder, psychosis, skin pigmentary melanin abnormalities, deafness, arthritis, and diabetes mellitus. The free radical theory of aging proposes that free radicals underlie the aging process itself, whereas the process of mitohomesis suggests that repeated exposure to free radicals may extend life span.
Because free radicals are necessary for life, the body has a number of mechanisms to minimize free radical induced damage and to repair damage which does occur, such as the enzymes superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase. In addition, antioxidants play a key role in these defense mechanisms. These are often the three vitamins, vitamin A, vitamin C and vitamin E and polyphenol antioxidants. Further, there is good evidence bilirubin and uric acid can act as antioxidants to help neutralize certain free radicals. Bilirubin comes from the breakdown of red blood cells’ contents, while uric acid is a breakdown product of purines. Too much bilirubin, though, can lead to jaundice, which could eventually damage the central nervous system, while too much uric acid causes gout

it is the collagen or the glue that binds the skins cells that get damaged by the free radicals along with the effects of age and exposure to radiation from the sun. it is not just a matter or insulating the skin from the free radicals but also dealing with our genetic code that makes us age. Notice that black people tend to look younger (less wrinkly) as they get older than other races on account of the extra protection from melanin
